Glute Kickback Machine
The glute kickback machine is a glute isolation exercise where you brace your torso against a pad and push a footplate or lever back with one leg until your hip is fully extended. It isolates the gluteus maximus with little help from the lower back or quads, and the fixed path makes it easy to push close to failure.
Also known as: Machine glute kickback, Glute kickback, Glute press machine, Rear kick machine

What muscles does the glute kickback machine work?
Primary movers
- Gluteus maximus
Assisting muscles
- Hamstrings
- Gluteus medius
The gluteus maximus is the body's main hip extensor. A kickback isolates that action, driving the thigh back behind the body with the torso fixed in place.
Most kickback machines have you lean forward on a chest pad with the working hip flexed at the start. That lets the glutes work from a stretched position through to full extension, a wider range than many glute exercises cover.
The hamstrings also extend the hip and always help. Keeping the knee bent at around 90 degrees reduces their contribution, which puts more of the work on the glutes.
Because the machine controls the movement path and supports your body, there is no balance or spinal loading demand. Every rep can be pushed hard without the lower back being the limiting factor.
How to do the glute kickback machine
Setup
- 1
Adjust the chest or forearm pad so you can lean forward with a flat back.
- 2
Place one foot on the platform or behind the roller pad, with the knee bent.
- 3
Plant the standing foot firmly and hold the handles.
- 4
Set your hips square to the machine and brace your abs.
Execution
- 1
Push the platform back and up by driving your heel, extending your hip.
- 2
Keep the knee angle close to fixed through the rep.
- 3
Stop when your hip is fully extended and you feel a strong glute squeeze.
- 4
Pause for a second at the top.
- 5
Lower under control until your hip is flexed and the glute is stretched.
- 6
Complete all reps on one side, then switch legs.
Common glute kickback machine mistakes
Arching the lower back
Pushing the leg too high so the lower back arches to finish the rep. The extra range comes from the spine rather than the hip.
The fix: Stop when the hip is fully extended. Keep the ribs down and the back flat against the pad.
Rotating the hips
Letting the working hip open out to the side to push more weight, which shifts the work to other muscles.
The fix: Keep both hips square to the machine for every rep.
Straightening the knee
Kicking the leg straight, which turns the exercise into a hamstring and quad movement.
The fix: Keep the knee bent at a consistent angle and drive through the heel.
Rushing the reps
Swinging the platform back and forth so momentum does the work.
The fix: Pause at the top and lower over two seconds.
How many sets and reps?
| Goal | Sets | Reps | Load | Rest |
|---|---|---|---|---|
| Glute hypertrophy | 3 | 10–15 per side | Moderate, 1–2 RIR | 60 s |
| Strength | 3 | 8–10 per side | Heavy | 90 s |
| Finisher | 2 | 15–20 per side | Light, 1 s pause | 45 s |
Use the kickback machine after compound lifts such as squats, hip thrusts or deadlifts. Two to three sets of 10 to 15 per leg is enough. Because it isolates the glutes, it is a good way to add glute volume without more lower back fatigue. Start with your weaker leg and match the reps on the stronger side.

Frequently asked questions
What muscles does the glute kickback machine work?
Mainly the gluteus maximus, with the hamstrings assisting and the gluteus medius helping to stabilise the hip. Keeping the knee bent reduces the hamstring contribution and puts more of the work on the glutes.
Is the glute kickback machine effective?
Yes. It isolates the glutes through a large range with little spinal load, which makes it easy to train hard. It works best as an accessory alongside compound lifts like hip thrusts and squats.
Glute kickback machine or cable kickbacks?
The machine is more stable and easier to load heavily. Cable kickbacks need more balance and core control, but most gyms have a cable station. Both train the glutes well.
Why do I feel kickbacks in my lower back?
You are probably pushing the leg too high and arching the back to finish the rep. Stop at full hip extension, keep the ribs down and lower the weight if needed.
How many reps should I do?
Ten to fifteen reps per leg for two to three sets works well for most people. Push close to failure, since the machine makes it safe to do so.
