How to do it

Place both hands on the flat base of a flipped Bosu ball and set up in a plank with your shoulders over your hands and body straight. Drive one knee toward your chest, then quickly switch legs in a steady running motion. Keep alternating knees to chest while your core fights the wobble of the unstable base.

  1. 1Your abs and hip flexors driving each knee toward your chest
  2. 2Your shoulders and core working to stay stable on the wobbly base
  3. 3A strong plank line from shoulders to heels throughout

Common mistakes

  • Don't let your hips sag or pike up as you switch legs
  • Avoid swinging your legs with momentum or losing your grip on the base
  • Don't hold your breath or round your shoulders; keep a tight plank
