Reverse Hyper
The reverse hyperextension is a machine exercise: you lie face down with your hips at the edge of a pad and swing your legs up behind you against a pendulum load. It works the glutes, hamstrings and spinal erectors through hip extension, with the load heaviest at the top of the swing.
Also called: Reverse Hyperextension, Reverse Hypers, Reverse Hyperextension Machine, Reverse Back Extension · Equipment: machine · Pattern: hinge
Step by step
- Lie face down on the pad with your hips at its edge so your legs hang freely, and grip the front handles to anchor your upper body.
- Hook your ankles under the roller or into the strap, with your knees nearly straight and a small, fixed bend.
- Squeeze your glutes and hamstrings to swing your legs back and up until they are about level with your torso.
- Hold the top briefly without arching your back to lift your legs any higher.
- Let your legs swing back down under control, resisting the pendulum rather than letting it drop.
- Settle at the bottom without bouncing, then start the next rep from a controlled hang.
- Squeeze the glutes to lift the legs
- Legs up to horizontal
- Knees soft and fixed
- Control the swing down
- No bounce at the bottom

What goes wrong, and the fix
Whipping the legs with momentum
Fix: Slow the tempo, use a lighter load and bring the legs only to horizontal.
Arching the back to gain height
Fix: Squeeze your glutes and finish with your legs level with your torso.
Bouncing at the bottom
Fix: Pause briefly at the bottom and start each rep from a still hang.
Knees bending through the rep
Fix: Set a small knee bend at the start and hold it for the whole set.
Hips sliding off the pad
Fix: Set your hips right at the pad edge and grip the handles firmly.
What the research says
Rehab & prehab · first choiceMuscle growthGeneral fitnessSport performanceEndurance
- Muscle activation — One EMG study found the reverse hyperextension produced higher peak glute, hamstring and back-extensor activation than a back extension, while a second found higher overall glute and hamstring activity in the back extension. The two small studies disagree.
- Stretch and squeeze — The load is heaviest with the legs near horizontal and lightest at the bottom. Research on leg training favours full-range and long-muscle-length work for growth, so many programmes pair it with a hinge such as the Romanian deadlift.
- Sets and reps — A common approach is 2–4 sets of 10–20 controlled reps as an accessory after the main lifts. There is no direct research comparing schemes for this exercise.
