So the internet is divided by people who believe in hand conditioning and with those who don't believe in hand conditioning. With styles like Wing Chun, Karate, Tiger Claw, Snake and Crane having centuries of experience behind them and actually using conditioned hands and arms to strike with, I strongly believe that hand conditioning is a real thing. That said, I really want to start conditioning my finger tips, forearms, knuckles and palms. For the past year, I've been hitting my heavy bag without my gloves and I can see the progress already; my knuckles are bigger and denser, allowing me to strike harder and last longer doing so. However, I have to wait for long periods of rest for my knuckles to heal before I can condition them. In those periods of rest, I want to focus on the aforementioned areas and start a systematic process of training while I wait for another part of my body to rest. The longest I had to wait, was a few months before I could strike my bag again.
