Attach a resistance band to a low wall mount or wrap the center of a band around a bench or furniture leg. Either put both of your feet through the handles tightly, or tie the two ends of the band together and place the band over your toes. Lie on your back facing the fixed point. Keep your back flat, abs tight, and place your hands on the floor or under your hips. Scoot away from the wall, until legs are only slightly bent when raised up off the floor.
EXHALE: keeping back flat and abs tight, bend knees in toward your shoulders. INHALE: Slowly lower to starting position to complete one rep.
Make it harder: Scoot farther away from the wall for more resistance.
Make it easier: Stay closer to the wall and decrease range of motion.
