Reversing the movement, torso pinned to the pad while the legs swing up behind you, makes this the glute-led entry in the back extension family while the spine mostly holds still. Load it lighter than instinct suggests and use higher reps; the swing builds momentum quickly at the top.
How to do the Machine Reverse Hyperextension
- Adjust the leverage machine to fit your body and secure your feet in the foot pads.
- Lie face down on the machine with your upper body hanging off the edge and your hips resting on the pad.
- Cross your arms over your chest or place them behind your head.
- Engage your glutes and hamstrings to lift your legs upward until they are parallel to the ground.
- Pause for a moment at the top, then slowly lower your legs back down to the starting position.
- Repeat for the desired number of repetitions.
Tip: Keep the neck neutral and look at the floor a few feet ahead of you, not up at the ceiling.
Muscles worked
Primary
Glutes · Legs
The glutes drive the hip extension that lifts the torso, and rounding the upper back slightly with a pelvic tuck shifts more of the work onto them.
Secondary
- Hamstrings — The hamstrings assist hip extension and get more of a stretch the straighter your legs are on the pad.
- Spine — The spinal erectors work both to hold the back in a rigid position and to bring the torso up, and you should feel a burn along both sides of the lower back.
Common mistakes
- Hyperextending at the top — the goal is a straight line from head to heels, not an arch; stop when the torso is level with the legs.
- Pad set too high — if the pad sits above the hip crease it blocks the hips from folding and forces the lower back to do all the bending; set it just below the hip bones.
- Using momentum — swinging the torso up fast turns it into a bounce; take two or three seconds on the way down and lift smoothly.
- Adding weight too early — bodyweight sets of 15 with a full pause at the top should feel easy before you hold a plate.
Where it fits in a workout
Back extensions are a good accessory after deadlifts or squats, or a stand-alone lower back builder on an upper body day. They pair well with a hamstring curl or a reverse hyperextension on adjacent equipment.
