Repeat the motion for another cable crunch. Release the crunch and return to the start position, with back slightly arched. At this point, force a few more inches into the crunch. However, back pretty much stays parallel to the floor, within the range of the arching and curling.Īt some point, you will not be able to go further because your abs will begin fatiguing. If you keep it arched, you’ll have difficulty with form.įor cable crunches, you will be arching low back (when you uncurl), and then rounding (when you curl). This is normal.Īs long as elbows are on track to meet thighs, you know you are cable crunching properly.Īs you progress into the curl, round out the back. However, elbows will probably not make it to your thighs. If elbows hit the floor, you are not cable crunching correctly. Now, without losing that 90-degree angle with your legs, curl trunk as though you want to touch elbows to thighs. Your back is parallel to floor in this start-position, though it should have a slight arch. Forearms should be parallel to each other. While holding rope, place inside of forearms tightly against ears. Maintain this angle throughout the entire cable crunch set. Set yourself up in the start-position: upper legs vertical, forming 90-degree angle with lower legs. Grab rope while standing, then get to knees.ĭetermine where knees should be on the floor (use a mat), so that if you were to bend forward at the pelvis, your head will have room to come down without grazing the weight stack. Use the rope for the hand device, and hold it just above the knobs or knots. For women, 80-100.ĭo not assume this is too light, because when you bring proper form and 20-35 reps into the picture, this much-lighter weight will be challenging. For best results with the cable crunch, your rep range should be 20-35. If the weight is heavy enough, you will not be able to curl your trunk/abs in as tightly as possible. Using too much weight will prevent you from using correct form. Many people make the mistake of pulling the weight down with their hands, yanking with forearms and shoulders, fooling themselves into thinking their abs are doing this work. This way, they integrate with your head, and become part of the weight you are pulling. To avoid getting arms involved, they must be firmly against sides of head. Thighs should form a 90-degree angle with calves. So when you do cable crunches, duplicate this position. Regular ones are often performed with legs positioned up in the air, thighs vertical, and calves horizontal: a 90-degree bend. When you perform cable crunches while sitting on your heels, this sabotages best effort at curling in the trunk and abs.Īgain, think of a regular crunch. This is a common mistake with cable crunches: The person keeps back straight while bouncing up and down from the lower back. Merely bobbing up and down from a lower-back pivotal point will not target the abs. So when you do cable crunches, this same motion should be happening: back flexion. When you do a typical crunch, your trunk folds up and your head comes towards thighs. Think of the cable crunch as an inverted crunch. ![]() ![]() ![]()
