your body does not work that way.

History has shown that the more you use your body parts, the stronger it gets.

Before this, i only use my whole body to walk around, and spend so much time sitting down. my peak was like 120kg when i was in my early 20's

Now, everyday i cycle+workout more than 2 hours everyday. On a bicycle, i can go 90-100RPM on max gear on the road no problem (which is around 35kmh on a straight road).

The body gets stronger the more you use it. this includes your brain, your legs, your arms, your mind, your heart.

So i dont see why didi should not follow the same rule.
