3. Reverse Crunches Workout

Reverse Crunches use the transverse abdominis, the deepest muscle in your abs.

While lying on a mat, with your feet off the ground, bring your knees up into your mid section, heels closer to your butt and toes pointed down.

Your hand should be behind your head with your thumbs behind ears or at your side facing down.

Keep your hamstrings flexed and knees bent and roll your hips and thighs toward your chest.

Return back to starting position.
