Otis Up Waist Max
Starting flat on your back with a weight plate held at your chest, you sit up and keep rotating until you reach a fully upright, twisted finish position. Combining a sit up and a rotation in one continuous rep works the front and side of the core rather than just the six-pack muscles.
