Hyperextension (on Bench)

The bench hyperextension, also called a back extension, raises the torso while the legs remain supported. The demonstration uses a horizontal bench; a purpose-built 45-degree back-extension station provides a different setup. A reverse hyperextension lifts the legs while the torso is supported and is a separate movement.

Go to the movement steps

Check your setup before you start

Back extensions move the torso while the legs are supported. Reverse hyperextensions move the legs while the torso is supported. Use a dedicated back-extension station when available; do not add load to an improvised setup.

• Equipment and support: a stable back-extension station or a bench with secure leg support; do not use an unsupported bench edge.
• Use stable equipment that supports your legs and lets your hips bend. Follow its setup instructions and check that the support is secure.
• Use secure leg support; a loose bench or unsupported lower body can make the setup unstable.

This summary uses the checked guidance on this page. Read the full movement steps and compare the demonstration before starting.

How to Do the Hyperextension (on Bench)

1. Use stable equipment that supports your legs and lets your hips bend. Follow its setup instructions and check that the support is secure.
2. Position your hips near the pad edge with your legs supported. Start with your arms crossed over your chest rather than pulling on your head.
3. Lower your torso slowly by bending at the hips, keeping your back in a comfortable, controlled position.
4. Raise your torso until it lines up with your legs. Stop there instead of arching farther backward.
5. Pause briefly, then repeat without bouncing. Learn the setup and range without extra weight first.

Back extension versus reverse hyperextension

Back extensions move the torso while the legs are supported. Reverse hyperextensions move the legs while the torso is supported. Use a dedicated back-extension station when available; do not add load to an improvised setup.

Technique & Form Tips

The hips bend as the torso lowers. The hip extensors help raise it while the back muscles support the torso. The equipment angle changes support and range; a flat bench and a 45-degree station require different setups.

Common Mistakes to Avoid

• Unsupported legs: Use secure leg support; a loose bench or unsupported lower body can make the setup unstable.
• Overextending at the top: Finish with the torso aligned with the legs rather than leaning farther backward.
• Bouncing at the bottom: Choose a range you can reverse smoothly under control.

How to Breathe During This Exercise

Breathe in during the controlled lowering phase and breathe out as you raise the torso.

Comfort and Control

Stop if the movement causes pain. If you have an existing condition, ask a qualified professional about an appropriate exercise and range. If discomfort persists, stop and ask a qualified professional about an appropriate exercise and range.

General guidance: Mayo Clinic on weight-training technique. Follow the specific movement steps above for this variation.

Movement focus

Check the support position and trunk movement shown in this demonstration. Similar-looking back exercises can move the trunk, hips or legs; follow this guide rather than assuming they use the same action.

FAQ

What should I check before the Hyperextension (on Bench)?

What equipment do I need for the Hyperextension (on Bench)?

You do the Hyperextension (on Bench) with a stable back-extension station or a bench with secure leg support; do not use an unsupported bench edge. Make sure your equipment is set up safely before starting. If you work out at home or have limited gear, check out our alternative exercises below.

What form mistake should I watch for on the Hyperextension (on Bench)?

One mistake to watch for is unsupported legs: Use secure leg support; a loose bench or unsupported lower body can make the setup unstable.. Use a comfortable range and a controlled return; reduce the load if you cannot maintain the demonstrated setup.

How many sets and reps should I perform on the Hyperextension (on Bench)?

To build muscle size, aim for 3 to 4 sets of 8 to 12 reps with 90 to 120 seconds of rest. To build pure strength, focus on 4 to 5 sets of 3 to 6 heavier reps with 2 to 3 minutes of rest.
