This exercise is an advanced exercise for your lower abdominal muscles and your legs, and you will need flat bench and ankle weights to perform it.
Lie on a flat bench. Put your legs straight out. Legs are off the bench end. Your hands are placed under your butt and your palms are facing down.
Bend your knees and pull your upper thighs into your midsection, and then slowly return to the starting position with your legs straight and off the bench end.
