Exercise guide

Reverse Hyper On Flat Bench

  • Intermediate
  • Compound
  • Rep-based
  • Back
  • Hips
  • Lower legs

This isolation movement targets the glutes and hamstrings while providing a gentle decompression for the lower back. It is highly effective for building posterior chain strength and hip extension power without adding vertical load to the spine.

Muscles worked

Primary

  • Glutes
  • Hamstrings

Secondary

  • Erector spinae

Equipment

  • Body weight

Setup

  1. Lie face down on a flat bench with your hips positioned at the very edge of the bench so your legs hang off freely.
  2. Firmly grasp the sides or the front of the bench to stabilize your upper body and prevent sliding.
  3. Engage your core and keep your legs together with a slight bend in the knees.

How to do it

  1. Exhale as you lift your legs toward the ceiling by squeezing your glutes until your legs are roughly in line with your torso.
  2. Hold the peak contraction for one second, focusing on driving your hips into the bench.
  3. Inhale as you slowly lower your legs back to the starting position, maintaining tension in the hamstrings.
  4. Perform the movement with a controlled tempo, avoiding the use of momentum or swinging.

Form checklist

  • Keep your neck neutral by looking down at the bench rather than forward.
  • Stop the upward movement once your legs are level with your hips to avoid excessive lower back arching.
  • Ensure your hips remain in firm contact with the bench throughout the entire range of motion.
  • Keep your core braced to stabilize the spine during the leg lift.

Pro tips

  • Focus on 'pulling' with the glutes and reaching your heels toward the back wall to maximize posterior chain engagement.
  • Imagine you are trying to lengthen your spine as you lift your legs to encourage decompression of the lumbar vertebrae.

Make it harder

  • Hold a small dumbbell securely between your feet to add resistance.
  • Place a mini-band around your ankles to increase tension and engage the glute medius.
