Team Inferno in GA!

A lot of work and a lot of fits going on at camp.

We have 4 Wobble-naught & My0-facts fitters working with the Inferno team.

The LH Thomson company, the company who makes the stems & seatpost is hosting the week long camp. Above is Jeff Hopkins learning a new way to approach the bike. Jeff is 28 and has won many races while here in the US. We hope he wins more!

The point is, you are never too old to learn how to refine your game!

24 Hours of Old Pueblo! A win for Pua!

24 Hours of Old Pueblo!

This Weekend Team Ergon (Pua, her husband Ron, Dave Weins, Jeff Kerkove & Dejay Birtch) raced the 24 Hours at the old Pueblo just outside of Tucson, AZ in the 5 person Coed division.

We set out to do more laps than any other Coed team. We were able to "win" the overall coed with 21 laps! Also we were only 36 minutes behind the overall winning Kona all male 4 man team, matching them in lap count!

Pua on the Wobble-naught fit and use of Dartfish was able to pull the fastest overall female day and night laps, pulling her fastest on her and the team's final winning lap! She also did 5 total laps, one more than all of us guys!

The world best look out for this gal!

Getting under my skin! Decision based on how a rider looks in a trainer!

The ideas that come out really get under my skin, rather your skin!

So-called custom bikes use simplified sizing methods or use a CAD program.  Many estimate the frame size from charts of a rider's height.  But the most common method is to go to some retail store that pay someone to stand on the floor for most of the week, most part-time while they are in school and read the tags of the latest and greatest that you could have done yourself?  Most just have the rider mount a bike or use a adjustable contraption while they are in a trainer/jig and stand to the side and make their decision based on how the rider looks while pedaling.  After all, god forgive, they would have to pay for a fit!!!  You even see saddles price $450 being picked up and that person won't pay for a fit?  They already know why they hurt?  After all, they are pros, they have been hurting for years!

There are drawbacks of them all, but the largest is the last method.  You can have some sizing jig and move the person while on the saddle where you think they need to be?  Even ask them how does that feel? Who's the pro?  The problem here is the appearances even with years of experience are not enough, because of a few things!

First fact, the bike is in a trainer, that means the rear wheel is locked in space! That means pressure and force is going into your body!  Most of it between your legs!!!

This is a movement sport, the bike moves, so that method throws the fit off!  The bikes either moves under the rider or the rider moves over the bike.  That is why we don't eye it!  

How many times do we hear of someone spending too much time in the trainer and then their performance level is not what it should be when the roads are open and the weather is nice. Many harm the integumentary system, tissues that provide a protective membrane that guards the deeper tissue.  Secretions from the skin are slightly acid in nature, providing it the ability to prevent bacterial invasion.

This is more of an issue for the gals than the men!  The skin contains two types of glands that produce important secretions (sebaceous and sweat glands).  Sebum helps to lubricate the surface of the skin, and sweat helps to cool the body.  Nerve fibers located under the skin act as receptors for sensations such as pain, temperature,  pressure, and touch.  Thus, the adjustment of an individual to her or his environment is dependent on the sensory messages relayed to the brain and spinal cord by the sensitive nerve ending in the skin.

There are other things that happen to this very complex system!  Skin tissues aid in maintaining the body temperature. Nerve fibers coordinate (thermoregulation) by carrying messages to the skin from heat centers in the brain that are sensitive to increases/decreases in body temperature.  Impulses from these fibers cause blood vessels to dilate to bring blood to the surface and cause sweat glands to produce the watery secretion that carries heat away!

How comes the news!  More and more saddles are becoming more flat!  That means if you miss where the sit bones hit, well the "saddle is not what will wear out".  I watch the sell of saddles everyday and can't believe the lack of understanding?  Then you have all the new saddle tools that take a outline of your sitbones?  This has nothing to do with where the saddle is in space?

Just more mass marketing ideas vs. correct bike fitting? When its more to do where the saddle is in relationship to the bottom bracket.  Your pedal style!  Can you understand that too wide of a saddle will wear out the layers of the skin.  


Not that long ago, we had ski decks for people to get on a rotating deck with a grade and work on their ski turns.  This did not work!  Yes it was cool and yes it was fun for the first few times.
But nothing is like being in the real world!

Number one, maximum efficiency can't be made because the bike is locked in the trainer.  True the frame dimensions will allow him to adopt to the position, but only within very narrow parameters.  For the most part, if the seat tube is too vertical, you might not be able to set the saddle back as far as you might need.

If the frame is too small, it's impossible to set the handlebars in space at the right distance, so you have to use a oversized stem and that will compromise the riding!

No one just goes out and buys new golf clubs and even with the perfectly fitting custom clubs on the first try and hits the ball like Tiger Woods!  But the Tiger Woods still go to someone who can help them with their strokes!  Even pros slowly modify their bikes after many years to get them right, or they get dropped!

Can we say, at least the best ones do, and don't have a problem perfecting their style and position as they gain more experience.  You can win races on a imperfect bike, but your career will be short!  You can't perform at the highest level for very long with the wrong mobility.

Even when you stand at the side and watch with a careful eye, a knee that seems to be operating in the correct mobility, wear and tear can be going on!  Think about your foot being attached to the pedal, the force on the attached pedal, the muscles firing reduces the tibia from rotation.  This has to be picked up at the femur or the hip or even your lower back.

A poor foot position will cause problem within the femur's rotation in relation to the tibia and cause problems around the joints of the whole leg!  Any abnormal tensions in any muscle is a "red flag".  This poor alignment, even with the cyclist's hip being under less stress from their body weight on the saddle can cause problems.

Many things need to be looked at as the body is constantly subjected to great stress in cycling!
Getting  fit using CAD has made a difference for many, and now we have the Dartfish to really help you outside!

Valentine's Special

To have a heart or not? That is the question?

The top picture will not do you very well without something inside!

It is Valentine's Day, so let's get to the heart of it! Without a good heart count your game over.

You don't have to know the language of medicine, the cardiovascular system nor know its anatomy or physiology to know that the pulmonary circulation that works with blood picks up oxygen (O2); and blood loses carbon dioxide (CO2). You don't have to know the systemic circulation and the aorta and its arterial branches.

You perhaps know, that there is two major phases of the heartbeat. These are called diastole (relaxation) and systole (contraction).

There you have it! Even this muscle has to contract and then relax! To move your legs, your muscles need the best range of motion and the best line of pull. The bike is a frame and it dictates the geometry and its mechanical characteristics. Basic frames need work to modify them for the different conditions you wish to ride and for the rider's build. Yes a lighter bike climbs well, but might have a shimmy on downhill. A heavier frame increases stability for improved handling at higher speeds. Light or heavy, both require you to use your muscles.
So it now sounds like a matter of feel (mushy vs. liveliness) and that for sure depends on your style. Again, you have to use your levers that are worked by your muscles. Get that wrong and don't expect performance.

So what does all of this have to do with your heart and legs?

Your legs act as your second heart! The perfect range of motion and the best line of pull, given the game you want to play, allows every muscle in your legs to contract the muscles, then relax! If they don't? Well they act like your heart! They fail! And you can't put a pacemaker in your legs! But if you use your brain, you can control the pace of them!

It seems that there is a special day each month to drive us to buy something for someone. If we need it or not. Perhaps we need a national bike fitting day and make that a traditional event! It might help people more than they know if they get the correct info for what they want to do.
How often do we see a mtb fit from traditional road needs, its not the same game!

There is a word on the first half of mountain biking "mountain" and most of the time that means climbing with hills. That means the severity of hills forces you to put more effort into it and if your machine is not right, well! Your pedal habit on say a flat might not work on a hill.
Even where you sit on the saddle makes a difference.

Bicycling is a game and that means you need to learn how to play it "outside". It is not just about training! It must be pointed out that a cyclist can only achieve optimum efficiency if their bike is perfectly adapted to their build and what they want to do! And this a huge problem that is easy to state by x,y,z ideas than to solve! You have to have the mental will to push your athletic limits. Don't expect a leisure bike set up to help you on the hills. Don't expect the traditional dimensions (saddle height, setback, handlebar distance, saddle-stem height, even cleat placement, etc...) of road to help you on your mtb.

Valentines Day is yet more traditional proposals on things that are well, traditional. The same holds true for training based on your heart! Can you say traditional stereotyped generalizations! Kind of like most of the bike fits that are traditionally stereotyped.

It also seems that much effort is placed on training by cultures as topics of physical preparation underline the sport. This is good, and will serve us well as we keep our feet on the ground or in our sport, the pedals! If your feet are on the pedals in the correct fashion.

Cycling is just like many sports that require the athlete, whether professional or amateur, to perform their task and exercise their skills using on a not seeming complex machine. In other words we are dependent on the equipment. The driving force is not just the belly of the muscles fueled by the heart, but also how the machine itself is set up!

But, understand this, a road bike fit is not mtb fit, a XC fir or a tt fit, nor is a tri fit or even the same as a track tt fit, and the list goes on! The nature of the athlete changes profoundly as they mounts the machine they wish to ride! Then you have the many style that more follow "form follows function". Some sitting upright very perched, other's bridge? It is cool to look good perched upon their streamlined machine when they pull up to get their Java. Other's are bridged Like the wings of a bird, their legs beat rhythmically to propel them forward, the legs beat alternately in a regular motion. Just like the heart, its muscle that makes you go!

On a flat terrain much of what the effort is all about is to overcome wind resistance. But yet we see the many fits that have you perched upright? Great for going at slow speeds, and on flats it works as very little energy is used to move forward. Everything changes when the cyclist decides to go uphill or faster. You need to pump out the watts!

This is where the wide range of possibilities of fitting comes down to earth! As we said, putting your feet back on the ground or pedal! You can dream all you want e.g. to be a god like Mercury who had winds on his sandals and haul it. Effort is the key and setting a powerful pace according to your age, your motivation, and your physical abilities. Remember this, that the watt, a unit of power, represents the work accomplished when a given mass goes to work.
Even a untrained cyclist can easily make about 200-250 watts. We attempt to make use of the strongest muscles of the human body. Many don't understand that cycling works the entire body. It is not a natural thing! That opens up a huge can worms!

A few facts about the heart, it is a muscular, cone-shaped organ, about the size of a clenched fist, that pumps blood throughout the body and beats normally about 70 times per minute by coordinated nerve impulses and muscular contractions.

The weight of the heart in men averages between 280 and 340 g and in women, between 230 and 280 g. You mean there can be a difference in the size of one's pump to meet the metabolic requirements of body tissues?

Every year thousands of heart's are given to sweetheart's for Valentine's Day!
It seems the heart means more about your soul vs a pump?

Tradition has it for many, the heart is a way to train? Kind of the same thing as the "heart is your soul" on Valentine's day.

Why don't we give a lung or a liver or a "brain" for Valentine's Day? They are important also.
Is the brain more of the soul over the heart or is that heartless? If we gave a brain to people, perhaps more would know that the heart is just a pump.

Think of the pumping sounds of water within a pump that pumps water from the river to the fields as you hear the sound of the valves (a dull, prolonged "lub" with the closure of the valves at the onset, then the second sound, a short, sharp "dup," occurs. There is yet another sound, a weak, low-pitched, dull 3rd sound. It is sometimes heard and is thought to be caused by vibrations of the walls of the ventricles when they are suddenly distended by blood from the atria. It is called "diastolic gallop". There is also a "presystolic gallop".

Sounds? Pumping sounds, gallop sounds? Sounds like what we do when we use sEMG to listen to the muscles firing or not.

There is even a instrument, a stehoscope, used in mediate auscultation, consisting of two earpieces connected by means of flexible tubing to a diaphragm, which is placed against the skin of the patient's chest or back to hear heart and lung sounds. In the hands of someone who knows what the sounds mean can be used for auscultation sounds interpertations.

Then we have a electrocardiogram (EKG, ECG) not (EDG, EEG or EHD) that a technologist might use say during a operation. The (EKG, ECG) is a device used for recording the electric activity of the myocardium to detect transmission of the cardiac impulse through the conductive tissues of the muscles. It shows a model of the waveform or a graphic record that can be read!

That is what sEMG is about! The "Analogy -using bird songs or the sound of a thunder strom that produces a roll of thunder that moves in all directions, producing lighting sending the sounds to the recording electrodes (microphones). The biological energy reaches the reference electrode, and only the energy that is unique to each recording electrode is passed on for further signal conditioning and display.

The analogy helps to clarify a concept. Monitoring the amplitude of bird songs in the field allows you to recorde the bird songs (Geese) as the birds fly toward the two microphones, each microphone receives a slightly different sound, since the birds are closer to one microphone than the other. The differential amplifier simply subtracts the level of song on one microphone from that of the other, presenting the difference as the index of loudness. The louder the birds sing, the larger the difference and the higher the loudness meter. We can see and hear if a muscle is on or off and even its % of use within each pedal stroke!

Back to the sounds of a heart. Additional heart sounds include clicks, murmurs, rubs, and snaps!

Yes the "stroke volume - the amount of blood ejected by the ventricle during a ventricle contraction of the heart" is important, as it needs to move the blood at a rate that we get the most volume moved! Much more important that how fast the pump runs! You only get 4-O2's to one Red Blood Cell (RBC).

Other factors affecting the hearbeat are emotion, exercise, hormones, temperature, pain, and stress.

Bottom line, if the plants (muscles) don't get the water (blood), they don't make it! They fail!

Most of us have "Sweet Hearts" in our lives! Maybe that is why we are here? So have a (heart/soul) and push them towards a healthly lifestyle.

When it comes to heart disease, everyone seems to know that lifestyle is important! A good diet, lots of physical activity, not smoking, maintaining a trim waistline and being able to control stress go a long way toward preventing a heart attack or failure of the water pump to work.

Much depends on your lifestyle! So play the odds and do the things everyone knows are part of a healthy lifestyle! Work on a healthy pump for your plants!

Then if you really want to learn how to make more horsepower, use a little horse-sense, cut the "Sweet Talk" and get your "Valentine's Special" a correct fit and suggest they use a power meter to record more truths! Not to say the old pump is not important, but the power meter along with the best fit is better science of riding faster!

The quest for a technical edge never stops, just be sure you don't get the "Sweet Talk" only. Different cyclists have different needs, and each cyclist's individual characteristics (whole heartly) should be taken into account when equipment is selected or adjusted. That is why we use our CAD over mass marketing or eyeing things.
Its best to be open to every aspect of technology and techniques! We can help you gain new insights on how to optimize the dynamics between your machine and maximize the performance.

Techniques are outside, not in a trainer and that is why we use Dartfish!
True, it is only a tool, so you need to know what to look for and we do!
It might just change their day!

Happy Valentine's!

What's it like in Idaho to ride this time of year?

Many wonder what's it like to ride in Idaho this time of the year!

As you can see, its very white! Best have some sunglasses!

Good thing the snow melted a little to find the way home!

The sign shows how far Boise, ID is from this point!

This might be the best way to get there! Cars get stuck or get hit by snow slides! Road bikes "well"?

As you can see, the locals have a hard time.

Just up the road was the remains of a kill, made by a mt. lion!

So where is one to train?

Note that Jenn is really focused and works as hard as anyone! She is using Dartfish to refine her game. Here she is working on how to address the bike indoors! She is also using Dartfish outside!

While outside, using the Dartfish to review the real world needs of cycling can provide some very real facts about one's game!

We are working with people on the road, outside, as man must learn a different posture and discover that it's not just the feet but the saddle and the handlebars that support the effort.
Even while using Dartfish, one might seem to be immobile, but the trunk, spine, and arms make a dynamic system. The muscles regulate the tension according to the changing situations.

At this time, we must point out that the Dartfish is a very powerful tool, we can follow and capture the moves of all. We had a rider that we were working with, using the Dartfish on a local ride. We then captured local star by chance and followed her until she reached the others.
With that, some don't wish to have their angles reviewed by the world (rightly so!) and want their moves treated as strictly confidential.

We respect that wish! We will not analyze a position to be placed on our blog or without their written agreement to do so! Again, we understand how powerful this tool is and how it could divulge, disclose information that is proprietary to their performance.

In modern cycling there is an increased need to monitor and measure performances. This is certainly the case with Dartfish. These tools will provide feedback that can be used for later analysis. This holds true when we are out using the Dartfish on the cyclists when others ride into view.

If someone jumps into the view of the Dartfish, they then become subject to the power of Dartfish. This happen this past weekend! So we would like to report the facts!

1) We always take 100% responsibility for any activity we are involved in.

With that, we are learning how to use Dartfish outside and how to respect others! It is also our focus to never gossip and never get in the middle of communications between other people.

2) We also go to the source of anything that makes us uncomfortable.

3) Anyone can go out and flim racers, races, training rides, etc... But they might not have the Dartfish and know what they are looking at!

It seems that the blog with good intentions to show people riding in Idaho this time of year using the Dartfish was sent to Kristin by someone who can gossip "email" style? We wonder if they are even in her camp, as she is there to race, not have someone reviewing our blog, sending her (their concerns) about her being on the blog?

With all respect to Kristin Armstrong, we removed her Dartfish pics from the blog. The last thing we intented to do is to divulge, disclose the confidentiality in any manner, either directly or indirectly her pedal stroke without her consent!

The point of all this is in the our world of high-performance cycling we have some very powerful tools and those tools need confidentiality! The Dartfish is so revealing it can be utilized to one's methods and methodologies. That can adversely affect the livelihood of a World Champion!

Kristin is our friend and has been from the days of being on web cast on the Daily Peloton, where gossip and under minded people impacted her also. She has our highest respect!

(sEMG) Surface Electromyography to refine your stroke??

Many practitioners, using traditional methods debate the use of sEMG techniques?

Many don't understand how we use it!

Through the wonders of contemporay science and technology, a whole series of devices and techniques are becoming available to researchers.

The reasons why people are unable to continue muscular work and why they experience fatigue depend on several general factors, including the nature of the activity, the training and physiological status of the individual, and environmental conditions. Because physiologicaol systems are often matched in their capacities, during exercise stress it is somtimes difficult to identify a single factor that failed in an attempt to maintain exercise intensity.

During athletic contraction, muscular fatigue usually appears to be a peripheral phenomenon and due to fatigue of the muscles. The CNS and associated motor neurons and neuromuscular junctions appear to be "far superior" to skeletal muscle in maintaining function. It has been learned that the heart is not thought to fatigue and cause reduced ecercise power output. In other words, it much like a car, the more gas you give it, the faster the motor will move you down the road, at a cost! But if you don't have any horsepower, well don't get in a race, because the motor that uses more muscle mass will win!

Much research is going on about V02max (maximal O2 consumption) in setting the upper limit for aerobic metabolism and endurance. Two possibilities are considered! One is that V02max is limited by 02 transport from the lungs to contracting muscles. The other possibility is that V02max is limited by the respiratory capacity of contracting muscles. Some believe that endurance is directly related to V02max (i.e., the greater the V02mac, the greater the endurance). Other support the posibility that endurance is determined by peripheral factors like mitochondria to sustain high rates of respiration.

At present, we must conclude that V02max is a parameter set by maximal oxygen transport, but that endurance is determined also by muscle respiratory (mitochondrial) capacity. We also need to understand that it is better to use more muscle mass if one wants to make speed!

Muscle mass of contracting can influence V02 during exercise, once a critical mass of muscle is utilized, V02 is independent of muscle mass! The influence of muscle mass is revealed in the observations that V02max during bicycling with one leg is less than that when cycling with two legs. Running will be greater than bicycling do to gravity and the use of more muscle mass.

V0zmax apparently increases as active muscle mass increases to a point beyound which O2 delivered through the circulation is inadequate to supply the active muscle mass.

The ability of nerve and muscle cells to respond to chemical (neurotransmitter) stimuli ultimately "governs" all human motor behavior.

Electromyography (EMG) is a measurement tool that is used to identify the recruitment of motor units in skeletal muscle. An investigator can measure muscle electrical activity. Both the frequency and amplitude of the electrical activity can be measured, and this provides insight into actual recruitment patterns and the type and number of motor units being used during physical activity. In addition to measuring EMG, measurements of muscle force can be made, thus allowing an analysis of the relationship between force and EMG.

By studying muscle preparations, we have learned that the force of the overall muscle is controlled by two mechanisms during "voluntary contractions." One mechanism is to alter the frequency by which a given motor unit is recruited, a concept that is called "rate-coding."
First it is true that a intact muscle, a single muscle fiber, a single motor unit, the frequency of stimulation increases, so does the force output! The second mechanism to increase overall force output during voluntary contractions is to recruit "more motor units."

Complicated movements involve some part of the brain!

Most learned movement patterns, especially those movements that require sensory input (like hitting a baseball), require the participation of one or several areas of the brain. The motor cortex is in direct control fo the learned movement patterns. The learning of intricate motor tasks involves the programing of the motor cortex. The initiation of motor tasks involves the playing back of stored programs in which motor units in active and supporting muscles are recruited in a precise pattern of time, space, frequency, and amplitude.

Man kind has some essential movement patterns built into the CNS through the process of evolution. These primitive movements involve locomotion (e.g. walking, running, cycling, swimming) and appear to be located in the spinal cord. Even at the youngest age, you can watch a little kid pedal at the basic form! True, these primitive spinal cord movement patterns are activated under the control of higher cortical centers. Even Tiger woods had a golf club in his hands at a early age, but had to learn more!

Far too many rider's ride their bikes at the primitive level, very basic locomotion. Even the pro baseball player spends much time learning how to picth!!! Why not cycling? You will see people pedal in all sorts of ways?

Human movement during sports, like movement during other human endeavors, is under the ultimate control of the brain and the central nervous system. Therefore, understanding the neural controle of movement, using Myo-facts sEMG/Dartfish is of primary importance.

First, we don't use surface electromyography for assessing pain related problems. We don't use needle EMG or watch nerve conduction velocity suitable for bone and nerve related problems, they are insensitive to muscle, tendon, ligament and articular dysfunctions. We should also point out that traditional methods for assessing soft tissue pain related problems, such as palpation, are ultimately subjective!

We are not in the pain industry, we leave that to the physical medicine practitioner. We do use surface EMG technology to specifically monitor muscle action poentials (MAPs), and this is known to be sensitive to soft tissue injuries. Again, we don't use sEMG for ill care!

We do look for dysfunction homologous muscle pairs (or between agonist and its antagonist or synergist) during the pedal stroke. We can point out to your very eyes an imbalance in relative stiffness in the muscles that participate in a specific movement. These imbalances are thought to faulty CNS motor control problems, along with peripheral factors such as inefficient length-tension relationships and passive myofascial compliance with a poor saddle/cleat setup and bad motor skills. The relationship between muscle impairment and psychologic factors becomes clearer.

Do we not think about the correct golf swing or in our case the correct pedal stoke? Even Tiger Woods uses Butch Harrman, as does Phil Mickelson to refine their golf swing? So what's up with us refining your pedal stroke?

Observed functional limitations can be seen with a poor fitting bike. Surface EMG techniques and associated feedback displays can make the user more efficient. Fore example, sEMG can help identify inappropriate muscel substitution patterns and thus refine the pedal or the exercise. Motor copy templates can be used to assist in learning new recruitment patterns for a more powerful pedal stroke.

In health care, today, it is very common to teach a patient a set of exercises (stretching & strengthening exercises) and give them a handout to remind them of what they are to do until the next visit. We use sEMG to monitor the actual ability to activate the desired muscle. In real time, we can help them refine the pedal stroke to make it more effective.

No question, sEMG monitoring provides objective documentation trail of the impact on muscle function, thus allowing us to demonstrate gains. We see the sum of the effort in watts, and the watts increase with a improved, refined, pedal stroke.

If a posture is bad, movement may be compromised or muscle substitutions may appear.
We can show elevations in muscle activity. One could argue that that its weight placing an undue strain on the peri-articular structures or by the build up of lactic acid associated with muscular efforts required by the posture or movement.

We can teach a better postural alignment, and it is much better to show how the muscles can relax with the new correction. Many have caught onto their needed correction, based upon what the sEMG has taught them.

It has been shown in sports, for many who are professionals that muscle work better if the muscle relaxes during the stretch. When one reads the sEMG, a problem can be seen with assessing! The muscle stretch receptor gets stimulated causing the muscle to become active.
Now think about the speed of the pedal stroke and the speed of the muscle firing?

We can point out to you where you are stretching your muscles too much! Correct that on the fly, all while you pedal. Then we use the Dartfish, to break it down to you, one stroke at a time.
Real motor templates can be used to assist in learning a refined pedal stroke.

The sum of the work then provides you with the recordings of wattage!

It has been pointed out that many in the physical medicine field claim that we don't provide the best feedback, given the use of the muscles e.g. gas exchange of O2 & C02 "ADP to ATP ect....

That is true, we don't use sEMG to to test your blood, we just use it for seeing if a muscle is on/off, for a better model of a better pedal stroke. The results of people learning, taking that biofeedback to their game, putting more focus to their stroke has made a difference!

A poor pedal stroke, used 5,000 times per hour is not good, even if the V02max is at what ever value! Hitting a tennis ball in the sweetspot is always better than to the outside of that sweetspot.

Results are the end results! Every stroke counts no matter what time of year! Its hard work!
