The Smith reverse hyperextension is a hip-focused posterior-chain exercise performed face-down on a bench with the hips at the edge and the feet hanging free. Using the Smith machine bar for stability, you raise both legs upward behind you to extend the hips, making it an effective movement for building strength and endurance through the hips and lower back.
How to do the Smith Reverse Hyperextension
- 1Set the Smith machine bar to roughly hip height and position a flat bench lengthwise underneath it.
- 2Lie face-down on the bench so your hips sit at the very edge and your legs hang straight down toward the floor.
- 3Reach forward and grip the Smith bar or the sides of the bench firmly to anchor your upper body.
- 4Let your legs hang fully relaxed with your feet just above the floor — this is your starting position.
- 5Keeping your legs together and relatively straight, exhale and raise both legs upward behind you until your body forms a straight line or your hips reach comfortable full extension.
- 6Squeeze at the top of the movement, pausing briefly to maximize the contraction through the hips.
- 7Inhale and lower your legs back down slowly and under control until they return to the hanging start position.
- 8Repeat for the desired number of reps without letting momentum take over between repetitions.
Form tips
- Keep your core lightly braced and your pelvis stable on the bench throughout each rep to avoid excessive lumbar hyperextension.
- Move slowly on the way down — the controlled descent (eccentric phase) provides as much benefit as the lift itself.
- Grip the bench or bar firmly so your upper body stays anchored, directing all effort into the hip extension.
- Start with a smaller range of motion if you feel any discomfort in the lower back, and gradually increase as your mobility and strength improve.
Common mistakes
- Using momentum to swing the legs up instead of lifting with controlled hip extension, which reduces muscular tension and increases injury risk.
- Raising the legs far above parallel and overarching the lower back, placing unnecessary stress on the lumbar spine.
- Letting the legs drop quickly on the way down rather than lowering under control, which skips the most beneficial part of the movement.
- Positioning the hips too far onto the bench so they cannot move freely, limiting the range of motion and effectiveness of the exercise.
Frequently asked questions
What does the Smith reverse hyperextension target?
It targets the hips and posterior chain. The movement focuses on hip extension, making it useful for strengthening the back of the hips and the surrounding lower-back region.
Why use a Smith machine for reverse hyperextensions?
The fixed bar gives you a stable anchor point for your hands, letting you concentrate fully on the hip extension without worrying about balance or bar path.
How high should the Smith bar be set?
Position the bar at roughly hip height so you can lie comfortably face-down on the bench with your hips at the edge and your legs hanging freely toward the floor.
Can I do this exercise without a dedicated reverse hyperextension machine?
Yes — using a Smith machine with a flat bench is a practical alternative. The setup closely mimics the feel of a dedicated machine and works well in most commercial gyms.
How many reps and sets should I do?
For general hip strength, 3–4 sets of 12–20 controlled reps works well. Prioritize a full range of motion and slow tempo over adding load or chasing high rep counts.
