How to Do a Hamstring Curl with Swiss Ball?

  1. Lie down on your back, places your heel on the center of the the ball, with your hands to your side to stabilize your upper body.
  2. Exhale and roll the stability ball toward you  by curling.
  3. Lift your hips up so that you maintain  a straight line between your knees and your shoulders. Don’t let your hips sag.
  4. Inhale and return the ball to starting position.
  5. Repeat

Keep your feet together and don’t let them externally rotate as you curl. External rotation of your feet, over-engages your glutes and creates harmful tensions on your knees.
