I hear you have to flex ur abs when doing the crunches. so is it flexing outward, inward, or downward, what? i can flex many differrent ways.
. how about doin ab workouts where, when im down, my shoulders arent touching the floor. so they are flexed. and how far do i go up?
ab workouts are headaching. there are so many ways!!
