This list is too funny! Glad I read it, because now I don't feel so badly when I do things like:
-fall backwards on the stability ball during "STS Stab.Ball Abs", head first... even got a rug burn on my arm!
-barely nudge my butt upwards during levitation holds.
-punch myself in the face during kickbox (yeah, me too!)
And a whole long list of other stuff. But I just keep trying..
