Four-Part Reverse Curls
Tone your abs and back with our twist on the classic crunch.
Lie on your back with knees bent, feet on the floor, and hands lightly touching the sides of your head, elbows out to the sides. Push your lower back into the floor, then curl your legs up until thighs are about perpendicular to the floor. Next, raise your torso off the ground. Pause, then lower your torso only. Lower legs to finish the move. Repeat 12 times.
