No, because you mainly want to keep fit.

In fitness, the hands only play a role in grasping, supporting, pressing, holding and other actions, that is to say, assisting, and the impact on assisting is not very serious.

If you practice grappling, red sand palm, black sand palm, etc., your hands will definitely be deformed!

But in fitness, the effect of hands is very weak, and the real effect is on the muscle groups, such as abdominal muscles, chest muscles, dorsal sphincter muscles, deltoid muscles...

The deformability of the hand is affected by the frequency of direct use, not heavy brute force, and generally changes very little!
