Erase hand numbing, backache, knee pain and pain for saddle !! XD

[박정빈]

why DOVAL can erase hand numbing, backache, knee pain and pain for saddle???

All of that are completed from one condition, that is the resistance of 4 o'clock direction to 6 o'clock direction.

Now we should treat that hand numbing, backache, and pain for saddle are same phenomenon.

Easy to say,

 

the lumbar is leaned  to front too much,  so the weight of upper body attack arm.

so hand numbing can be occurred.

also, there are collapses of body balance so pain for saddle can be occurred by square weight.

and then, what is the condition of making good body balance??

you can think it easily.

if there were no saddle at bike, much ineffective energy exists  when you ride.

also if there were no handle, same thing does too. 

many people don't consider the stability of feet's position.

above three are inevitable to make your body comfortable for riding.

 The completion of three points (handle, saddle, feet).

main problem is feet's stability.

human body's maximum output section is about 4 o'clock direction on crank.

but most cranks in the world are designed to relieve resistance after  4 o'clock direction.

because of this situation, body balance is broken and rider can get illness.

  

Many of you may agree this fact.

before DOVAL coming, people may not know about this fact.

you should think what is the best thing that helps exercising. 

and you can ask your self after looking around your situation.

if you agree my opinion, i recommend DOVAL to exercising.
