2 years I have been doing bodybuilding but my body skin has not become harden! Some say that a sunburn under the sun will make your skin harden but I don’t want to turn my white skin on black! Are there any recommendations on how to make your skin harden? Thank you in advance!
In general, your skin will only harden if it is used in that way (e.g.: you need to walk barefoot in order to have more resistant skin on your feet). Thus, the general answer to the general question is twofold:
- if your skin didn't harden after two years, it probably doesn't need to
- if you want your skin to harden regardless, you will need to use your body accordingly.
That being said: hardening your skin in general seems both impossible and a bad idea: the skin is designed to be flexible. But if you're specifically talking about, say, the hands or the knuckles, I can recommend doing specific exercises to slowly make your skin used to requirement of hardening. (E.g. for the latter: knuckle push-ups with decreasing layers of cloth between your hands and the floor.)
