I have an athlete, who for months had BEAUTIFUL tap swings. I'm not sure what's happened- poor kid peels every. darn. time. For obvious reasons, she's scared and honestly so am I. What are common reasons for peeling? We've tried less chalk, more chalk, grips, no grips. She's hollow in the backswing and generally pretty tight (I'm quick to correct if not). We only have a set of unevens and a set of p-bars, so swinging in straps, on pit bar, or even just high bar isn't possible. She does fine with regrip swings w/bent knees on parallel bars. What could be going on!?
