Reverse Crunches

Place ab mat on the ground and sit on mat with your back off the mat and knees together. Begin with feet 3 inches off the floor and legs bent to 90 degrees. Place your palms face down on the floor for support. Tighten your abs to extend your legs forward, then contract your knees inward to your chest. Pause at the top of the movement, then return to starting position. Repeat for all reps. Stand up and recover.

Keep your head up and your hips & chest in proper alignment. Breathe out on the way forward. Breathe in on the way back.
