Crunches

Sit on a flat bench with your back to the cable. Grasp the rope with both hands so that the palms are facing each other and are above your shoulders as shown in the figure. Tip: Let the weight stretch your lower back a little. This will be your starting position. As you exhale, without moving your hips, begin to twist, bringing your elbows closer to your hips. On an inhale, slowly return to the starting position. Complete the required number of repetitions. Variations: You can use an expander to perform this exercise.
