Reverse Cable Crunch
Cable Ab Exercises Hits: 2002
Lie down on the floor in front of a low pulley and loop the ankle straps around your ankles. Keeping your knees bent about 90 degrees, use your abs to roll your hips back towards your chest. At the top of the movement your thighs should be close to your chest with your tailbone off the ground. Pause there for a second, lower, and repeat.
