How to Do a towel crunch abs exercise
The towel crunch is similar to the traditional abdominal crunch. The purpose of the towel is to stabilize the head and provide comfort. It also takes away the tendency to want to pull the chin forward into the chest, which compromises the cervical spine.
Lie down on your back with your knees bent and feet flat on the floor. Place a towel behind your head. Hands should be spaced at least 20 inches apart. Tighten your abdomen and roll your torso forward. Your shoulders, head, and neck should elevate slightly, but should not come too high off the ground. As you crunch, be sure to exhale. Perform this exercise slowly and hold the crunch position for 2 or 3 seconds before returning to the starting position.
Try to keep your head and neck in line with your spine. Do not crank your neck with the towel.
