Favorite Ab workouts?

esmaythemermaid

Trying to get my abs back. I used to be a dancer/gymnist so I just naturally had abs from all that natural body workout. That was years ago.

Wondering what your favorite ab workouts are? Weather they be specific calisthenic moves or routines or a workout video that you're more keen to using.

Thanks in advanced
