Exercise guide

Bent Leg Kickback Kneeling

  • Beginner
  • Compound
  • Rep-based
  • Hips
  • Lower legs
  • Waist

This exercise isolates the gluteus maximus by using a shortened lever, effectively building glute strength and shape while minimizing hamstring dominance. It is an excellent bodyweight movement for improving hip extension mechanics and mind-muscle connection.

Equipment

  • Body weight

Setup

  1. Start 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.
  3. Distribute your weight evenly between your hands and the stationary knee.

How to do it

  1. Keeping your knee bent at a 90-degree angle, exhale and lift your heel toward the ceiling until your thigh is parallel to the floor.
  2. Squeeze your glute hard at the top of the movement for a one-second pause.
  3. Inhale as you slowly lower your knee back toward the floor, stopping just before it touches to maintain tension.
  4. Perform all reps on one side before switching to the other leg.

Form checklist

  • Keep your hips square to the floor; do not let the working hip rotate upward.
  • Maintain a neutral spine and avoid arching your lower back as the leg rises.
  • Keep your neck aligned with your spine by looking at the floor between your hands.
  • Ensure the 90-degree bend in the knee stays constant throughout the entire set.

Pro tips

  • Focus on driving the movement through your heel rather than your toes to better engage the glutes.
  • Imagine you are balancing a glass of water on your lower back to ensure your torso remains perfectly still.

Make it harder

  • Add three small pulses at the top of each repetition to increase time under tension.
  • Slow the eccentric (lowering) phase to 4 seconds to challenge stability and muscle control.
