I do mma and I always find ways to improve. One way I like to do that is to take some techniques and some other aspects from other martial arts styles and try to add them to my move set. As Bruce Lee once said “absorb what is useful, discard what is useless, add essentially what is your own.” (Forgive me if I got that quote wrong) I don’t have enough money to go to another place and learn other martial art styles though. My grandparents got me a LOT of martial arts books. The books they got me are aikido, wing chun, qin na, shuai jiao, judo, japanese jiu jitsu and jeet kune do. I’ve taken to reading some of them like the wing chun one. And since my grappling sucks I’ve also started reading the qin na books and shuai jiao books and my grappling has somewhat improved. Overall ever since reading those books I see some improvement. For example I’m getting better at trapping because of the wing chun book. But what are your guys opinions? Are books a good source to go off of? What do you guys think? And should I keep doing it?
