Jack Knife Abs – in and out

  • Start in a seated position on the bench with both hands grabbing onto the edge. Lean your upper body back as far as you can as you extend your feet out. Keep your chin up and back straight. Keep your knees slightly bent. You should be on your glutes. Engaging your core, bring your upper body forward and your legs in towards your abs. Return to the start position and repeat. Sanitize the equipment when finished.
