Seated Single Leg Half Circle
Seated Single Leg Half Circle Exercise Description
The Seated Single Leg Half Circle is a controlled, bodyweight hip drill performed while sitting upright. You actively lift and sweep one straight leg in a smooth semicircle without moving the torso, emphasizing pelvic stability and precise open‑chain hip motion. Primary contributors include the hip flexors (iliopsoas, rectus femoris), abductors (gluteus medius/minimus, tensor fasciae latae), and the adductor group, while the hip rotators help guide the femoral head and maintain alignment. The goal is clean, pain‑free arcs with a neutral spine and level pelvis, avoiding compensations such as leaning, slouching, or knee flexion. This teaches control and coordination through your available hip range using only body weight.

How To Do The Seated Single Leg Half Circle Exercise
‘- Sit tall on your sit bones with legs straight in front (floor or firm bench). Place hands beside your hips for light support.
– Stack ribs over pelvis; keep a neutral spine and level pelvis.
– Straighten the working knee; keep the ankle neutral with toes facing the ceiling.
– Lightly brace your trunk. Lift the heel of the working leg a few inches, moving from the hip, not the low back.
– Sweep the straight leg in a slow half circle in front of you— from near the midline to out to the side—keeping the foot off the surface.
– Keep the kneecap oriented upward; avoid twisting, leaning, or hiking the hip.
– Maintain a quiet nonworking leg and steady breathing; do not hold your breath.
– Stop before any pain, pinching, or pelvic motion. Lower the leg with control.
– Repeat the same controlled arc in the opposite direction as desired, then switch legs.
Seated Single Leg Half Circle Tips
‘- Sit tall on your sit bones with both legs straight in front of you before you start moving.
– Stack your ribs directly over your pelvis to help keep a neutral spine and level pelvis.
– Use your hands beside your hips only for light support, not to push or pull yourself.
– Fully straighten the working knee and keep the ankle neutral with toes facing the ceiling.
– Lightly brace your trunk so the leg lifts from the hip, not from the low back.
– Keep the heel lifted only a few inches and sweep in a slow, smooth half circle while keeping the foot off the surface.
– Maintain the kneecap pointing up throughout the arc and avoid twisting, leaning, or hiking the hip.
– Keep the nonworking leg quiet and still while the working leg moves.
– Breathe steadily and avoid holding your breath during the movement.
– Stop the arc before any pain, pinching, or pelvic motion, and lower the leg with control.
Seated Single Leg Half Circle Beginner Introduction
The Seated Single Leg Half Circle is a seated bodyweight movement that highlights smooth, controlled motion at the hip joint. From an upright position, one straight leg travels through a gentle arc in the air while the rest of the body remains steady and tall. The action comes from the hip rather than the lower back, so the trunk, pelvis, and nonworking leg act as a stable base while the moving leg traces a slow half circle in front and out to the side.
This drill places strong emphasis on the hip flexors, the front of the thigh, the glutes at the side of the hips, and the inner thighs, with the deep hip rotators quietly guiding the leg path. The focus stays on clean, pain‑free arcs and even posture, without slouching, leaning, or bending the knee. Because the motion is “open chain,” the leg moves freely while the torso stays quiet, building awareness, coordination, and fine control through the available hip range using only body weight.
