How to do it

Set the TRX straps to mid-calf length and place your feet in the foot cradles. Assume a plank position with your hands under your shoulders and body straight. Drive one knee toward your chest while keeping the other leg extended, then quickly switch legs, mimicking a running motion. Continue alternating knees to chest at a steady pace, keeping your hips level and core engaged.

  1. 1Assume a plank with your feet in the TRX straps and drive one knee toward your chest, feeling your abs and hip flexors engage
  2. 2Keep your shoulders over your wrists and maintain tension in the straps as you alternate legs
  3. 3You should feel your core working hard to stabilise your hips and spine

Common mistakes

  • Don't allow your hips to sag or pike; maintain a straight line from shoulders to heels
  • Avoid swinging your legs with momentum or letting the straps slacken
  • Don't hold your breath or round your shoulders; keep a strong plank position
