Hip abduction machine
The seated hip abduction machine targets the gluteus medius well in EMG studies, but evidence that it builds muscle is thin: in the one trial, 10 weeks of cable hip abduction grew the gluteus medius and minimus by about 4% and mostly the upper gluteus maximus. It is a reasonable add-on for the side glutes; hip extension and squatting exercises build more overall glute.
What the science says
- Grows the side glutes a little Limited evidence
Attarieh et al. (2026) had 17 adults train one leg with cable hip abduction and the other with cable hip extension (about 10 sets a week, 8–12RM, 10 weeks). Abduction grew the gluteus medius plus minimus by about 4%; this was cable-based abduction, not the seated machine, and a single small trial.
- Hip extension builds more overall glute Limited evidence
In the same trial hip extension grew the gluteus maximus by 9% versus 5% for abduction; abduction growth was concentrated in the upper gluteus maximus (+10% proximally).
- Targets the gluteus medius with less TFL Moderate evidence
de Almeida Paz et al. (2022) found in 11 men that gluteus medius activation was similar on the machine, in side-lying abduction and in the clamshell, but the machine had the best gluteus medius to tensor fasciae latae ratio. This is activation, not measured growth.
How to do it
Muscles trained: gluteus medius, gluteus minimus, glutes
- Sit with the back against the pad and the pads on the outside of the knees.
- Push the legs apart to your widest comfortable range and pause 1 second.
- Return slowly without letting the stack touch down between reps.
- Keep the torso still; don't rock to move the weight.
How to apply it
Use it as an optional add-on after compound leg work, with moderate-to-high reps taken close to failure.
Who should be careful
Low-risk for healthy adults. Anyone with hip pain or a hip condition should have a physician or physical therapist set their training.
Frequently asked questions
Does the hip abduction machine grow the glutes?
A little: in the one trial, cable hip abduction grew the gluteus medius and minimus by about 4% and mostly the upper gluteus maximus over 10 weeks.
Is it better than hip extension exercises?
No for overall glute size: hip extension grew the gluteus maximus by 9% versus 5% with abduction in the same trial.
Why use the machine instead of side-lying raises?
In an EMG study it activated the gluteus medius as much as side-lying abduction with less tensor fasciae latae involvement.

More exercises
- Back squat Strong evidence
The barbell back squat reliably builds the quadriceps, glutes and adductors and is one of the best-studied lower-body exercises in training research.
- Front squat Moderate evidence
The front squat holds the bar on the front of the shoulders, which keeps the torso more upright and loads the knees less than the back squat while recruiting the thigh muscles about as much.
- Leg press Strong evidence
The leg press builds the quadriceps about as well as free-weight squats and also grows the glutes and adductor magnus, with no balance or spinal-loading limit.
- Hack squat (machine) Moderate evidence
The machine hack squat lets you squat deep on a fixed track with your back supported, which makes it easy to push the quads close to failure.
- Romanian deadlift Moderate evidence
The Romanian deadlift is a hip hinge that loads the hamstrings and glutes at long muscle lengths, and trials of stiff-leg deadlifts and similar hip-extension exercises show real hamstring growth, mainly in the semimembranosus and biceps femoris long head.
- Conventional deadlift Moderate evidence
The conventional deadlift trains the whole posterior chain and grip and is a core strength lift, but research on its growth effects is thin: trials either use other deadlift variants or measure strength rather than muscle size.
