Prone Side Leg Lifts
Lying on your side, you raise the top leg toward the ceiling and lower it with control, isolating the gluteus medius on the outside of the hip. This small muscle steers your knee alignment in squats, lunges, and running, which makes this quiet floor drill more consequential than it looks. Coached by Maddy (NASM-CPT) — these are the exact form cues he gives on every client's first week.
Muscles worked
Sets & reps by goal
| Goal | Sets × Reps | Rest |
|---|---|---|
| Strength | 4 sets x 4-6 reps per side with a 3-sec top hold | 90 sec |
| Muscle | 3 sets x 9-12 reps per side | 60-90 sec |
| Endurance | 2-3 sets x 18-27 reps per side | 30-45 sec |
Level — Beginner
Beginner — deceptively simple; the honest version with stacked hips and slow tempo burns within ten reps.
Proper form — 5 cues
- Lie on your side in one straight line — shoulder, hip, knee, and ankle stacked.
- Rest your head on the lower arm and place the top hand on the floor in front for balance.
- Point the top kneecap straight ahead, then raise the leg to about 45 degrees.
- Lead the lift with the heel, keeping the leg long and slightly behind your body line.
- Lower over two seconds without letting the top leg rest on the bottom one between reps.
Breathing: Exhale as the leg lifts, inhale as it lowers, keeping the torso quiet throughout.
The 3 mistakes Maddy corrects most
Common questions
Why do side leg lifts matter if the movement looks so small?
Because the gluteus medius is a stabiliser, not a show muscle. It holds your pelvis level every time you stand on one leg — which is every step you walk or run — and it stops the knee collapsing inward under squats and lunges. Weakness there shows up as knee cave and hip drop, and this simple lift is one of the most direct ways to address it.
Should I feel this in the side of my hip or the front of my thigh?
The side of the hip, roughly where a trouser pocket sits. Feeling it mostly at the front of the thigh means the hip has rolled backward and the hip flexors have taken over. Re-stack the hips, point the toes slightly downward, drop the leg height, and slow down — the burn should migrate to the outer hip within a few reps.
How often can I train side leg lifts?
The load is light, so three to four sessions a week is reasonable, and many people use a short set as part of every warm-up before leg training or running. For strengthening, two or three harder sets per side, two or three times weekly, with the top-position hold, gives the muscle enough stimulus while leaving room to recover.
