Smith Reverse Hyperextension
- Intermediate
- Compound
- Rep-based
- Lower legs
- Waist
The Smith Reverse Hyperextension is a powerful posterior chain exercise that isolates the glutes and hamstrings by moving the legs against resistance while the spine remains unloaded. This variation provides a fixed path of motion, allowing for intense peak contractions and controlled eccentric phases.

Setup
- Position a flat bench or hyperextension pad perpendicular to the Smith machine bar.
- Set the bar height so it rests against your lower calves/achilles when your legs are hanging straight down.
- Lie face down on the bench with your hip crease at the very edge, allowing your legs to hang freely.
- Grip the front or sides of the bench firmly to anchor your upper body.
How to do it
- Inhale and brace your core, then exhale as you drive your heels upward against the bar by contracting your glutes.
- Lift your legs until they are roughly parallel to the floor or in line with your torso, avoiding spinal hyperextension.
- Squeeze your glutes and hamstrings at the top for a 1-second peak contraction.
- Inhale as you slowly lower the bar back to the starting position using a controlled 3-second eccentric tempo.
Form checklist
- Keep your neck neutral by looking slightly down or forward, not up.
- Ensure the movement occurs at the hip joint, not by arching the lower back.
- Keep your legs straight or with a very slight, fixed knee bend throughout the set.
- Maintain constant tension by not letting the bar rest at the bottom of the rep.
Pro tips
- Think about 'reaching' your heels toward the back wall rather than just lifting them up to maximize hip extension.
- To emphasize the glutes over the hamstrings, slightly rotate your toes outward (external rotation) as you lift.
Make it harder
- Add a 3-second isometric hold at the top of each rep to increase time under tension.
- Perform the movement with a '1-and-1/4' rep style, adding a small pulse at the top of the range.
Frequently asked
- What muscles does the smith reverse hyperextension work?
- The smith reverse hyperextension primarily targets the glutes and hamstrings, and also works the erector spinae and obliques as secondary muscles.
- What equipment do you need for the smith reverse hyperextension?
- The smith reverse hyperextension uses smith machine.
- Is the smith reverse hyperextension good for beginners?
- The smith reverse hyperextension is rated intermediate. Build a base with simpler variations first, then progress to it with light load and strict form.
