I can do situps fine (with feet held down), decline situps, ab straps, crunches, and whatever.
However, I def am not able to do a situp with knees up, and def not a v-up. I consider myself to be in decent shape, but can't for the life of me do this. Perhaps it's a weak back, or fat (i'm estimating myself around 15% bodyfat)?
