Yo, I'm a beginner I bought some foam chucks to start learning.... after a week I stopped using them. I love my wood chucks! so far I have smashed my ankle, my head twice, crunched my rib cage, I came close to getting a blak eye. I've started practicing doubles and smashed my hands a couple of times. I made fire chucks and burnt my arm first burn! O well its been about three months since I started, I dont smash myself bad any more, I am trying harder tricks I just keep dropping them now

wood is definitely the way to go!
