Why I do it: This is one of my favourite ab moves because it's so hard! Sometimes I do this holding a dumbbell or medicine ball, but doing it as a bodyweight move is intense enough.
- Begin on your back, with your legs straight and arms raised toward the ceiling.
- Roll up to sitting, focusing on the abs rounding the back. Roll back down to the mat slowly, one vertebra at a time.
- This completes one rep.
