The vertical leg crunch is similar to the traditional abdominal crunch. The difference is in the positioning of the arms and legs, as well as the range of motion (the upper back comes higher off the ground). Listed below are instructions for performing the vertical leg crunch:
Lie down on your back with your legs extended in the air. Straighten both arms and point your hands toward your toes. Slowly contract your abdomen by reaching for your toes. As you crunch the abs, be sure to exhale.
Lie down on your back. Extend legs in air. Extend arms.
Reach for toes. Exhale.
Return to starting point. Repeat exercise as needed.
