How to do back extension(hyperextension)
Master the setup, range of motion, and tempo for safer, more effective reps.
Overview
This movement targets the glutes, hamstrings, and the muscles supporting your spine. By hinging at the hips rather than rounding your back, you build a resilient posterior chain. It is an effective way to isolate the backside without the heavy spinal loading of a deadlift, making it excellent for both building muscle and improving posture.
Why Use It
- Strengthens the spinal erectors to help you stand taller.
- Isolates the glutes and hamstrings with minimal joint stress.
- Improves hinge mechanics that carry over to deadlifts and swings.
When to Use It
Use this as an accessory move after your main lifts. It works well as a high-rep finisher or as a warm-up to wake up your glutes.
Stats
Instructions for Proper Form
Setup
- The Pad Height: Set the pad just below your hip bones so you can bend freely at the hip.
- The Feet: Press your heels hard into the back plate to turn on your hamstrings.
Execution
- The Hinge: Lower your upper body by bending only at the hips. Keep your spine long.
Pro Tip: Push your hips hard into the pad as you descend to keep the tension in your glutes.
- The Rise: Squeeze your glutes hard to pull your torso back up to a straight line.
Coaching Cues
- Push the pad away with your hips
- Peel your chest up
- Stop at a straight line
Common Mistakes
- The Banana Back: Arching your back way past straight at the top, which pinches the spine.
- The Nod: Moving your head up and down instead of your whole torso.
- Pad Too High: Having the pad at your stomach, which prevents your hips from hinging.
How to Fix It
- The Banana Back: Imagine there is a wall behind your head; stop as soon as your body forms a straight line.
- The Nod: Pick a spot on the floor 3 feet in front of you and keep your eyes locked on it.
- Pad Too High: Move the pad down until it sits right at the crease where your legs meet your torso.

- Cross your arms over your chest.
Form Checklist
- Is your back staying flat?
- Are you initiating the move by pushing your hips into the pad?
- Are you stopping when your body is in a straight line?
- Is your neck neutral?
Range of Motion
Lower your torso until you feel a stretch in your hamstrings. Rise until your body forms a straight line.
Breathing Pattern
Inhale as you lower; exhale as you squeeze your glutes to return to the top.
Tempo Guidance
3-1-1: Three seconds down, a one-second squeeze at the top, and one second to lower.
Caution Notes
- Do not swing your body. If you feel a sharp twinge in your lower back, stop and check your pad height.
Programming
Treat these guidelines as practical programming defaults, then scale load, volume, and frequency to match the rest of the training week.

FAQ
Common Questions
Should I go all the way down?
Go as low as you can while keeping your back flat. If your back starts to round, you've gone too far.
