- Intermediate
- Compound
- Rep-based
- Back
- Hips
- Upper legs
The reverse hyperextension on a box targets the glutes, hamstrings, and erector spinae while providing a unique decompression effect for the lower back. It is an excellent movement for strengthening the posterior chain and improving hip extension power without heavy axial loading.

Setup
- Lie face down on a high box or flat bench so your hips are positioned right at the edge, allowing your legs to hang freely.
- Grip the front or sides of the box firmly to stabilize your upper body and keep your chest pinned down.
- Position your legs together with a slight bend in the knees and toes pointed down toward the floor.
How to do it
- Exhale and lift your legs upward by squeezing your glutes until your legs are roughly parallel to the floor and in line with your torso.
- Pause for one second at the peak of the movement, focusing on a maximum contraction in the glutes and lower back.
- Inhale and slowly lower your legs back to the starting position using a controlled 2-3 second tempo.
- Avoid swinging the legs or using momentum; keep the movement strictly driven by the posterior chain.
Form checklist
- Keep your core braced throughout the movement to protect the lumbar spine.
- Ensure the hinge occurs at the hips rather than excessively arching the mid-back.
- Maintain a neutral neck by looking slightly down at the box or straight ahead.
- Keep your upper body completely still by maintaining a death-grip on the box.
Pro tips
- Think about 'reaching' your heels toward the back wall as you lift to maximize hamstring and glute tension.
- Focus on the mind-muscle connection by initiating the lift with a glute squeeze before the legs even begin to move.
Make it harder
- Hold a small dumbbell or medicine ball between your feet to add external resistance.
- Slow down the eccentric phase to 5 seconds or add a 3-second isometric hold at the top of each rep.
