Side-Lying Leg Raise
Lead with the heel, hips stacked. The side-lying leg raise isolates the glute medius more directly than anything else in the library, and that muscle is behind a lot of knees that collapse inward. Keep the toe pointing forward and the hips stacked. Rolling the hips back hands the work to the hip flexor, which is why most people feel nothing.
Setup
- Lie on your side, body in a straight line, hips stacked vertically.
- Bottom arm supporting the head.
How To Do It
- Raise the top leg, leading with the heel and keeping the toe pointing forward.
- Stop when the hips start to roll back.
- Lower slowly.
Breathing
Exhale as the leg rises.
Common Mistakes
- Rolling the hips back, which hands the work to the hip flexor.
- Kicking up fast and dropping down.
Programming It
Two to three sets of 12-20 per side.
Why This Exercise Works
Nothing loads the glute medius as directly as this, and almost nothing else isolates it at all. It is unglamorous and it works, particularly for anyone whose knee drifts inward under load.
Where You Should Feel It
A specific burn on the outside of the top hip. It should feel small and local. Feeling it in the lower back or hip flexor means the leg has drifted forward.
Where It Fits in a Program
Unglamorous, and it fixes more knee complaints than most knee exercises. It belongs after the heavy work, when precision matters more than load.
Progressing and Regressing It
To progress the side-lying leg raise: add an ankle weight or a band, or hold the top for two seconds. To regress it: reduce the range, and keep the hips stacked.
Who It's For
Anyone with knees that collapse inward, and anyone who runs. Nothing else isolates the glute medius this directly.
Equipment and Substitutions
Nothing to buy and nowhere to be, which is the point. If it is too easy, the harder variations below are the progression, not added weight.

Common Questions
What muscles does the side-lying leg raise work?
The side-lying leg raise primarily trains the glute medius, hips.
How many sets and reps should I do?
Two to three sets of 12-20 per side.
What are the most common side-lying leg raise mistakes?
Most often: rolling the hips back, which hands the work to the hip flexor; kicking up fast and dropping down.
Can I do this without any equipment?
Yes. This version needs no equipment at all. It trains the glute medius, hips using bodyweight alone, which is why it travels well and works as a warm-up, a substitute, or a full session on its own.
Is this safe if I have an existing injury?
The side-lying leg raise puts the shoulder and elbow under load through a range many people have lost, so a cranky shoulder usually objects here before anything else does. Pain that pinches at a specific point is worth assessing; ordinary training discomfort is not. Not medical advice.
