Side Lying Leg Circle

How to do the Side Lying Leg Circle

1. 1Lie on your side on a flat surface with your body in a straight line, hips stacked directly on top of each other.
2. 2Rest your head on your bottom arm or prop it up with your hand, and place your top hand on the floor in front of your chest for light balance support.
3. 3Flex your bottom foot and press the inner edge lightly into the floor to keep your lower body stable.
4. 4Lift your top leg to roughly hip height, keeping the leg straight and the foot softly pointed.
5. 5Begin the circle by sweeping the leg forward (toward the front of your body), then upward, then back behind the hip, and finally down to return to the start — tracing a smooth, controlled circle.
6. 6Keep your hips stacked and your core braced throughout so that only the leg moves; do not let your pelvis rock or rotate.
7. 7Complete the prescribed number of circles in one direction, then reverse, sweeping the leg backward first.
8. 8Lower the leg fully, then roll to the other side and repeat the set with the opposite leg.

Form tips

• Move at a slow, deliberate pace — the muscles work hardest when you resist momentum and own every degree of the arc.
• Keep your hips stacked by actively pressing your waist away from the floor; letting the pelvis tilt shortens the range of motion and reduces the demand on the adductors and glutes.
• Think of drawing a circle on the wall in front of you rather than the floor beneath you — this mental cue keeps the leg moving in the true frontal and sagittal planes.
• Maintain a neutral foot position or a soft point; avoid aggressively dorsiflexing or plantarflexing, as ankle tension can shift focus away from the hip.
• For a greater challenge, widen the diameter of the circle gradually as your hip control improves rather than rushing to increase reps.

Common mistakes

• Letting the pelvis rock with each circle — this transfers load away from the target hip muscles to the lower back and reduces the effectiveness of the exercise.
• Using momentum to swing the leg through the arc instead of controlling each phase, which shortens the time under tension and limits muscle activation.
• Bending the knee during the movement, which reduces the lever arm and makes the exercise significantly easier than intended.
• Making the circles too small out of habit or tension — overly small arcs underuse the adductors in the downward phase and the glutes in the upward phase.
• Holding the breath during the exercise, which increases pelvic instability; breathe steadily throughout each circle.
