What is the proper form and technique for performing the kneeling cable crunch exercise?

To perform the kneeling cable crunch exercise properly, start by attaching a rope handle to a high pulley. Kneel down facing away from the pulley, grab the rope behind your head, and bring your elbows to your knees by contracting your abs. Keep your back straight and avoid using momentum. Slowly return to the starting position and repeat for desired reps.
