trying to do a hanging sit up. help me /fit/, before i kill myself. or suggest a better alternative. i have a boso ball and a pilates ball... anything?
bosu ball bike crunches, like doing a normal bike crunch only on the ball, works like a son of a bitch.

>>264273yes, its hard but it gets results
*runs to basement to use bosu ball*
