Pair this workout with my Tone the Legs, or do it as a stand-alone if stronger abs are a goal. Working all the muscles of your core, you'll perform a series of exercises that will alternate between a traditional abdominal exercise and a functional core exercise.

This workout is all levels, and osteoporosis-friendly ab exercises are suggested throughout.
