Seated Hip Abduction Machine
A seated machine that isolates the glute medius, the side-hip muscle that keeps knees tracking and stops pelvic drop on every stride.

What is the seated hip abduction machine?
The hip abduction machine resists outward leg movement against pads pressed by your knees. The primary mover is the glute medius, with help from the upper fibers of the glute max and the tensor fasciae latae. A strong glute medius prevents knee valgus on squats, lunges and running, and is critical for runners and field-sport athletes. It's also one of the few exercises that targets this muscle with proper progressive load.
How to do the seated hip abduction machine
Common mistakes
- Bouncing off the pads. Using momentum cuts the stimulus and pinches the lower back. Slow, controlled reps.
- Arching the lower back. Excess lumbar arch shifts the work off the glutes. Keep the lower back in contact with the seat.
- Half range. Tiny opens skip the stretch. Start narrow, push to fully open.
- Lifting hips off the seat. If hips rise, the load is too heavy and your form just broke. Drop a plate.
Variations & progressions
Banded side step
Loop a mini-band above the knees and side-step in a half squat. Activates the glute medius without machine load.
1.5 reps with pause
Full open, halfway in, back to full open with a 2-second hold, then return. Brutal time under tension.
Side-lying leg raise
Lie on your side, lift the top leg slowly through full range, with or without an ankle weight. Same muscle, no machine.
How to program it
Three protocols by goal. Pick one per cycle and aim for progression on load or distance.
| Goal | Sets × Distance | Load | Rest |
|---|---|---|---|
| Glute medius hypertrophy | 4 × 15 | Moderate, RPE 8 | 60-75 s |
| Strength | 4 × 8-10 | 75-85% 1RM | 90 s |
| Knee-stability finisher | 3 × 20 with 2 s hold | Light, 40-50% 1RM | 45 s |
