How to do it
With the thigh on the pad, extend the hip driving the foot back and up squeezing the glute; avoid arching the lower back to cheat. Controlled range with a pause at the top.
Muscles worked
Main muscle: glutes. When it plans weekly volume, every set of this exercise counts in full for glutes: the generator does not split it with other muscles.
Machine glute kickback: hip extension with the thigh supported and easy loading
If you are coming from the hip abduction machine, you will notice that the effort here goes back, not out. This is the machine for extending the hip, with the gluteus maximus doing the job, while abduction centers on the gluteus medius. The advantage over the cable kickback is that the machine holds your thigh or hip and guides the path: there is no body to balance, so you can push with more load and concentrate on one thing. The drawback is that the path is set by the machine, and the adjustment has to fit your height.
It fits after hip thrusts as one-sided work, to get near failure without tiring the lower back. It is also a good pick if your gym has no free cable or if the ankle strap throws you off. Add load slowly: on an isolation exercise, gaining a rep or holding a better pause at the top is real progress.
Before you start, line the hip joint up with the machine's pivot and adjust the support so the thigh is held firmly. As you push, think about sending the heel back rather than lifting the knee, and finish each rep without arching your lower back.

These are the values the generator uses to decide where the exercise goes within the session.
Recommended sets and reps
As an isolation exercise, it works best in 3–4 sets of 10–15 reps with 0–2 RIR. Use it at the end of the session to add volume without systemic fatigue.
Common mistakes to avoid
- Arching your lower back as the leg goes back: the range ends when the hip is fully extended.
- Not adjusting the seat and pads to your body: your joint should line up with the machine's pivot.
- Using too much weight at the cost of technique and full range of motion.
What the research says
As an isolation move, it is mostly a way to add volume to one muscle. Gentil and colleagues (2013) found that, in beginners, adding it to a multi-joint exercise gave no extra arm growth; it pays off later on, or for muscles the compounds barely reach.
You do not need to reach failure on every set: according to the meta-analysis by Refalo and colleagues (2023), stopping one or two reps short gives very similar growth. The generator prescribes it with RIR for that reason.

How Machine glute kickback compares with other glutes exercises
Of the 15 glutes exercises in the catalogue, ranked from least to most fatiguing by the values the generator uses, Machine glute kickback is number 1.
That makes it a good candidate for adding glutes sets at the end of a session or in heavy weeks, when you want volume without extra fatigue.
With different equipment, the same movement pattern offers 4 alternatives, such as Frog pump, Cable glute kickback and X-band walk.
| Exercise | Equipment | Fatigue | Technique |
|---|---|---|---|
| Machine glute kickback | machine | Low (0.3 out of 2.2) | Basic |
| Hip abduction machine | machine | Low (0.4 out of 2.2) | Basic |
| Seated hip abduction | machine | Low (0.4 out of 2.2) | Basic |
| Frog pump | bodyweight | Low (0.4 out of 2.2) | Basic |
| Cable glute kickback | cable | Low (0.4 out of 2.2) | Basic |
| X-band walk | resistance band | Low (0.4 out of 2.2) | Basic |
| Cable hip extension | cable | Low (0.5 out of 2.2) | Basic |
On a machine. In the meta-analysis by Haugen et al. (2023), with thirteen studies and 1,016 participants, there were no significant differences in muscle growth between training on machines and with free weights.
An isolation exercise. In the trial by Gentil et al. (2015), with untrained young men over ten weeks, the biceps curl and the lat pulldown were equally effective for gaining strength and size in the elbow flexors: isolation is not filler.

Frequently asked questions
What muscles does Machine glute kickback work?
Machine glute kickback mainly works the glutes muscle group, plus synergist and stabilizer muscles depending on the variation.
How many sets of Machine glute kickback should I do?
Between 3 and 5 sets per session, adjusting the total weekly volume for glutes to your level (about 10–20 sets per muscle per week).
Is the glute kickback machine better than the cable version?
Neither is better across the board. The machine is more stable and easier to load, so it suits heavier sets and beginners. The cable asks more of your balance and lets you adjust the angle freely. Use whichever lets you feel the glute most while keeping your lower back still.
