Hanging Knee Raise

The Hanging Knee Raise is a strength exercise on a pull-up bar for your hip flexors. Share of the load in the Zulta muscle model: lower abs 35%, hip flexors 21% and upper abs 19%.

Also known as: hanging knee

Level: BeginnerEquipment: Pull-up barMulti-joint (compound)

How to do it

  1. Hang from a pull-up bar with an overhand grip, hands shoulder-width.
  2. Pull your shoulders down slightly and let your legs hang still.
  3. Bend your knees and pull them up toward your chest, curling the pelvis up at the top.
  4. Pause when your thighs pass hip height.
  5. Lower the legs slowly until they hang straight, without swinging.

Tips

  • Think of tipping the pelvis toward your chest, not just lifting the knees.
  • Wait for the body to stop moving before the next rep.

Common mistakes

  • Swinging the body to kick the knees up.
  • Stopping at hip height without curling the pelvis.
  • Hanging on loose, shrugged shoulders.

Muscles worked by the Hanging Knee Raise

  • Lower abs Primary35%
  • Hip flexors Secondary21%
  • Upper abs Secondary19%
  • Obliques Secondary14%
  • Quads (rectus femoris) Minor5%
  • Forearm flexors Stabilizer3%
  • Lats (upper) Stabilizer3%

Share per muscle in the Zulta muscle model. The model spreads the load of one rep over 40 muscles, based on EMG and biomechanics research.

Bent knees shorten the lever. Lifting straight legs is hip flexion, so iliopsoas leads together with the lower abs, which tilt the pelvis back and hold it; hanging adds grip and lats.
