How to perform the Kneeling Hip-Flexor Stretch

  1. Kneel on one knee with the other foot planted flat in front, both knees bent to roughly ninety degrees. Cushion the down knee on a mat.
  2. Brace the core and tuck the tailbone under so the lower back flattens; this is what puts the stretch on the hip flexor.
  3. Shift your weight forward over the front foot until you feel a stretch across the front of the hip and top of the thigh of the kneeling leg.
  4. Keep the torso upright and hold for time, then swap which leg is forward.

Suggested working range: 20–45 seconds. Default progression: manual.

Common mistakes

  • •Leaving the lower back arched instead of tucking the tailbone, so the stretch never reaches the hip flexor.
  • •Letting the front knee travel far past the toes, loading the knee instead of opening the back hip.
  • •Leaning the torso forward rather than staying upright as the hips shift forward.

Variations & alternatives

Swap in one of these when the equipment is taken or the main lift has stalled.
