I saw people at the gym yesterday doing an abdominal exercise that I had not thought about, and I told them that I'd "steal" it for my blog.
Lie down in front of the cable machine. Your face and belly are up. You can make the exercise harder by putting mats beneath your buttocks o you have a bigger distance when you do your sit-up. use a weight that will give you a workout but will not have you feel big pain. Use the thick black rope as the attachment. Pull the rope so that either hand grasping it is next to each ear. Keep your chin up, and neck and shoulders relaxed as with an abdominal crunch. now do a sit-up, coming straight up to your knees. Repeat for four sets of ten repetitions.
