Lying Alternate Hip Extension

  • Beginner
  • Compound
  • Rep-based

This isolation exercise targets the glutes and hamstrings by extending the hip while lying prone, helping to improve posterior chain strength and hip stability. Its alternating nature allows for focused muscle activation and helps correct bilateral imbalances.

Setup

  1. Lie face down (prone) on a flat bench with your hips positioned at the very edge of the bench.
  2. Grip the sides of the bench firmly to stabilize your upper body.
  3. Let your legs hang naturally toward the floor with your toes lightly touching the ground.
  4. Engage your core and tuck your chin slightly to maintain a neutral spine.

How to do it

  1. Exhale and lift one leg toward the ceiling by squeezing your glute, keeping the leg straight or with a very slight bend in the knee.
  2. Lift until your thigh is roughly parallel with your torso, ensuring your hips stay pressed against the bench.
  3. Inhale as you slowly lower the leg back to the starting position with a controlled 2-second tempo.
  4. Immediately repeat the movement with the opposite leg, alternating sides for each repetition.

Form checklist

  • Keep your pelvis glued to the bench to prevent the lower back from arching.
  • Ensure the movement occurs at the hip joint, not by swinging the leg.
  • Keep your neck neutral by looking straight down at the bench.
  • Avoid rotating your hips as you lift the leg.

Pro tips

  • Focus on 'driving your heel to the ceiling' rather than just lifting your foot to maximize glute engagement.
  • Pause for one second at the top of the movement to emphasize the peak contraction of the gluteus maximus.
  • Keep your core braced as if you are about to be punched to protect your lumbar spine.

Make it harder

  • Wear ankle weights to provide additional resistance to the hip extensors.
  • Perform the movement with a 3-4 second eccentric (lowering) phase to increase time under tension.
