Exercise guide

Kneeling External Rotation

  • Intermediate
  • Compound
  • Rep-based
  • Lower legs
  • Shoulders
  • Upper legs
  • Waist

This exercise isolates the gluteus medius and hip rotators while challenging the core to maintain pelvic stability. It is essential for improving hip mobility and strengthening the lateral chain to support the lower back and knees.

  • Quadriceps

Equipment

  • Body weight

Setup

  1. Begin on all fours in a quadruped position with your hands directly under your shoulders and knees under your hips.
  2. Engage your core to create a flat, neutral spine from head to tailbone, avoiding any sagging in the lower back.
  3. Distribute your weight evenly across your palms and keep your gaze fixed on the floor between your hands.

How to do it

  1. Keeping your knee bent at a 90-degree angle, lift one leg out to the side away from your body as high as possible without tilting your pelvis.
  2. Exhale during the lift and pause for a moment at the peak of the contraction, squeezing the glute and obliques.
  3. Inhale as you slowly lower the leg back to the starting position under control.
  4. Alternate sides by repeating the movement with the opposite leg, maintaining a steady tempo.

Form checklist

  • Keep your elbows locked and arms straight to prevent the torso from dipping.
  • Ensure your hips stay parallel to the floor; do not let your pelvis rotate or lean toward the supporting side.
  • Maintain a consistent 90-degree bend in the moving knee throughout the rep.
  • Keep your neck neutral by not looking up or tucking your chin too deeply.

Pro tips

  • Focus on 'pushing' the floor away with your hands to keep your shoulder blades stable and your core fully engaged.
  • Imagine a glass of water resting on your lower back; perform the rotation without letting the water spill to ensure pure hip isolation and anti-rotational core work.

Make it harder

  • Perform the rotation with a straight leg to increase the resistance through a longer lever arm.
  • Add a 3-second isometric hold at the top of each repetition to maximize time under tension.
