Exercise of the Week: Jack Knife

ExcelCord Jack Knife

You will need a mid-level anchoring point for this exercise. Start lying on your back with your arms and legs fully extended. Keeping your legs and arms as straight as possible, fold at the waist and simultaneously raise your arms and legs so they are perpendicular to the ground. As you reach the highest point, attempt to touch your toes before slowly returning to your starting position. This is one rep. Perform 3 sets of 10 reps.
