Ok so I've been doing backwalkers on beam for about 2 weeks. I have it down on the low beam. But once I get to the high beam I completely freak out. My friends and I stack up 3 8 inchers on the lowest high beam. I can do it with all three of them on but once we start taking them off I get all nervous and I freak out and don't end up doing it. I had a coach stand there for me but I froze. Please give some tips on how to get over this fear!!
