The lever single leg hip thrust is a unilateral strength exercise that isolates the gluteus maximus while engaging the hamstrings and quadriceps as synergists. Performed on a leverage machine with one leg raised, it challenges each side independently to correct imbalances and build targeted hip extension strength.

How to do the Lever Single Leg Hip Thrust

  1. 1Set the leverage machine pad to a height that rests across your hips when seated on the floor in front of it.
  2. 2Sit on the floor with your upper back against the edge of the bench or pad of the machine, feet flat on the ground hip-width apart.
  3. 3Extend one leg straight out in front of you, keeping it elevated and parallel to the floor throughout the movement.
  4. 4Place the machine pad firmly across your hip crease on the working side.
  5. 5Brace your core and drive through the heel of your planted foot to thrust your hips upward.
  6. 6Extend until your hips are fully locked out and your torso forms a straight line from shoulders to planted knee.
  7. 7Hold the top position for a brief pause, squeezing the gluteus maximus of the working side.
  8. 8Lower your hips under control back toward the floor without fully resting, then begin the next rep.
  9. 9Complete all reps on one side before switching to the other leg.

Form tips

  • Keep your chin tucked slightly so your gaze follows your torso angle rather than craning your neck toward the ceiling.
  • Push through the full foot of the planted leg rather than just the heel to maintain knee stability throughout the range of motion.
  • Position the machine pad just below your hip bone — too high shifts load to your lower back, too low reduces glute activation.
  • Control the descent; letting your hips drop quickly reduces time under tension and limits gluteus maximus development.

Common mistakes

  • Hyperextending the lower back at the top of the rep, which shifts load away from the gluteus maximus and compresses the lumbar spine.
  • Letting the raised leg drop during the set, which breaks the unilateral challenge and reduces hip stability demands.
  • Planting the foot too far from the body, causing the knee to extend past the optimal angle and reducing glute activation in favor of the quadriceps.
  • Rushing through reps without pausing at lockout, which eliminates peak contraction and reduces the training stimulus on the gluteus maximus.
  • Allowing the hips to rotate toward the working side, creating asymmetrical loading and increasing the risk of lower back strain.

Frequently asked questions

What muscles does the lever single leg hip thrust work?

The primary muscle is the gluteus maximus. The hamstrings and quadriceps act as synergists to support hip extension and knee stability throughout the movement.

How is the single leg hip thrust different from the two-leg version?

Working one leg at a time roughly doubles the load on the gluteus maximus of the working side. It also exposes and addresses strength imbalances between legs that bilateral variations can mask.

Where should the machine pad be positioned on my hips?

Place the pad just below the anterior superior iliac spine — roughly at the hip crease. Positioning it too high stresses the lower back; too low reduces range of motion and glute activation.

How many reps should I do on each leg?

Complete all programmed reps on one leg before switching to the other. Match the rep count on both sides to avoid reinforcing any existing imbalance.

Can the lever single leg hip thrust help with lower back pain?

Strengthening the gluteus maximus can reduce compensatory demand on the lower back during hip extension. However, avoid hyperextending at the top of each rep, and consult a health professional before training with existing lower back pain.
