Single-Leg Circles
Single-leg circles are a Pilates-based movement done lying on your back, where you draw slow circles in the air with one leg. They strengthen the hip flexors and inner and outer thighs while improving how freely your hip joint moves. Because you're on the floor, there's no balance challenge — just focused, controlled motion. It's a gentle but effective way to keep your hips mobile and your legs strong.

Form cues
- 01
Lie flat on your back with both legs straight and arms resting at your sides, palms down.
- 02
Press your lower back gently into the floor so there's no arch — keep it there throughout.
- 03
Lift one leg toward the ceiling until it's as straight as comfortable, foot relaxed.
- 04
Begin drawing a circle with your whole leg, starting by crossing it slightly over your body's midline.
- 05
Keep the circle smooth and controlled — about the size of a dinner plate to start.
- 06
Hold your hips still; if one hip lifts or rocks, make the circle smaller.
- 07
Breathe steadily — inhale as the leg crosses the body, exhale as it sweeps back around.
- 08
Complete all circles in one direction, then reverse without lowering the leg.
- 09
Lower the leg slowly when done, then switch sides.

Common mistakes
Hips rocking side to side — if you feel your pelvis tilting with each circle, shrink the circle until your hips stay flat.
Bending the moving knee — the leg should stay as straight as comfortable; a soft bend is fine, but watch that it doesn't collapse.
Holding your breath — if you notice tension in your neck or jaw, you've stopped breathing; consciously exhale on each downswing.
Making the circle too large too soon — bigger isn't better here; a small, controlled circle does more work than a sloppy large one.
Letting the lower back arch off the floor — slide one hand under your back to check; if there's space, tighten your stomach and press the back down.
Scale it
Easier and harder variations
Easier
Bend the non-working leg and plant that foot flat on the floor for extra stability and lower-back support.
Use this if your lower back lifts off the floor or feels strained with both legs extended.
Harder
Extend both arms straight overhead on the floor to remove the grounding effect of your hands, increasing the core demand.
Try this once you can complete 10 circles each direction with hips completely still.
Note
Bend the working leg to a 90-degree angle and draw small circles with your knee instead of a straight leg, reducing hip-flexor load.
Use this if you have hip replacement, hip impingement, or hip flexor pain with a straight leg.
