How can i make my hands tough?
I do a lot of parkour on bars but it really hurts my hand how can i make my skin less sensitive?
Use chalk before you go and use moisturizer after you have done. after time your skin will thicken and you will no longer feel it.
Gymnasts use a white powder very much like chalk, it keeps the hands dry, and slippery.Not really a matter of how tough, but how to prepare.
There are different methods you may use to make your hands touch like weight lifting, swinging and chopping wood. You should also carry heavy loads in your hands and practice catching a ball with your hands.
