We just started working on back walkovers for next year's beam. I am hooking my thumbs together throughout the skill (they start hooked together and then they actually are placed on the beam with my thumbs hooked together). I started doing this to make sure that my hands stayed together and thought that I could unhook my thumbs as I got better. However, I tried to do some with my thumbs not hooked and my hands were very wide and the felt weird. Also, because my thumbs are hooked together it is causing one hand to turn and my hands sometimes land on the beam facing almost sideways. Is it dangerous to hook my thumbs together during my back walkovers? Will I get a deduction for not gripping the beam properly? Any tips? Thank you!
