Rope Crunch

Instructions

1. 
   Use a rope attachment on a cable machine and position yourself beneath it, on your knees and facing the machine. Reach up and grab the rope, then pull it down so it's level with your head.
2. 
   Do essentially an inverted crunch, lowering your elbows to your mid-thighs, keep your abs contracted while doing this. Then slowly return to starting position.
