Stability Ball Leg Curls

These are a huge favorite of celeb trainer Gunnar Peterson; he uses them with Kim Kardashian and even Queen Bey does these, along with hubby Jay Z.

 

  1. Lie on the floor with your arms palm down on the ground.
  2. Rest your feet on the stability ball.
  3. Inhale & bend your knees; your calves will roll the ball toward you.
  4. Exhale, and roll the ball back out.
  5. Keep your back and hips straight throughout the exercise.
