Hip abduction machine

Log this in the tracker

Also known as: Abductor machine

A seated machine for the glute medius, the side-hip muscle that stabilises every step.

What it is

The mirror of the adduction machine: knees start together and press outward against pads. It targets the glute medius and minimus directly.

Muscles worked

Primary: Glutes. Secondary: Gluteus medius.

How to perform it

  1. Sit tall with the pads against the outside of your knees and your back on the rest.
  2. Press the knees apart smoothly to the end of the machine's range.
  3. Pause briefly at the widest point without leaning back.
  4. Return under control, stopping just before the weights touch down.

Common form faults

  • Rocking backwards to gain leverage. Keep the back flat on the pad. Sitting upright biases the upper glute; leaning forward shifts it, but rocking is neither.
  • Slamming the stack on the way back. The return is half the set. Control it for two seconds.

Programming

15 to 25 reps suits this muscle. A good warm-up before squats and a cheap way to shore up single-leg stability.

Variations & substitutions

Frequently asked questions

Upright or leaning forward?
Leaning forward slightly lengthens the upper glute and many people feel it more there. Try both and keep whichever you feel working.
Will this fix knee pain?
Weak side-hip muscles contribute to knees falling inward, and strengthening them often helps, but pain has many causes. Treat it as one input, not a cure.
