The half seated leg circle is a bodyweight hip mobility drill performed sitting half reclined on the floor, tracing circles with one raised leg while the trunk holds position. The leg carries no external load, so the demand is control rather than strength: the hip flexors move the limb through a circle the joint may not normally reach, and the abs stop the pelvis from rolling along with it. The half reclined torso is what makes it harder than a lying leg circle. Use it in a warm-up or between sets.
What Muscles Does the Half Seated Leg Circle Work?
- Primary: Iliopsoas and rectus femoris (hip flexors)
- Secondary: Gluteus medius and minimus, adductors
- Tertiary: Rectus abdominis, obliques, triceps supporting the arms
How Do You Set Up for the Half Seated Leg Circle?
Sit on a mat with your legs extended in front of you. Lean the torso back to roughly 45 degrees and place both palms flat on the floor behind your hips, fingers pointing back, elbows soft. Draw the ribs down toward the pelvis so the lower back does not sag. Bend one knee and lift that foot a few inches off the mat while the other leg stays long and heavy.
How Do You Perform the Half Seated Leg Circle?
- Set the trunk angle by leaning back onto your hands with the ribs stacked over the pelvis.
- Lift the working knee until the thigh is off the floor, keeping the shin relaxed.
- Trace a slow circle with the knee, taking the thigh out to the side first.
- Reach the far point of the circle, where the hip opens fully, without letting the pelvis follow.
- Close the circle by bringing the knee back across the midline at the same speed.
- Lower the foot to the mat, then reverse the direction or switch legs for the next set.
What Are the Key Form Cues?
- Pin the pelvis: keep both hip bones level so the circle happens at the hip joint rather than by rocking the seat.
- Draw the circle slowly: the size of the circle should be limited by hip range, not by speed or swing.
- Keep the resting leg pressed long into the mat throughout.
- Share your weight evenly between both hands so the torso does not twist.
- Breathe out on the half of the circle that feels tightest.
What Are the Most Common Mistakes?
- Rushing the circle: the leg swings from momentum and the hip never reaches its end range, so slow each repetition until the path is even.
- Rolling the pelvis with the leg: the trunk does the circling and the hip barely moves, so keep the hip bones level and shrink the circle.
- Letting the lower back sag as the torso leans back: the spine hangs off the hip flexors instead of the abs, so keep the ribs down.
- Shrugging into the supporting hands: the shoulders rise toward the ears and the neck tightens, so press the floor away and keep the collarbones wide.
- Treating it as a strength set: the leg is unloaded, so adding reps past control gives you nothing; stop when the circle loses its shape.
What Are the Best Half Seated Leg Circle Variations?
- Lying leg circle: performing it flat on your back removes the trunk demand entirely.
- Straight-leg circle: extending the working knee lengthens the lever and widens the range.
- Ankle-weighted leg circle: a light ankle weight adds resistance to the hip flexors.
- Double-leg circle: circling both legs together makes the abs hold the whole load.
- Standing hip circle: the same hip path taken while balancing on the other leg.
How Do You Progress the Half Seated Leg Circle?
- Straighten the working leg before adding any weight, since leverage is the load here.
- Build from 5 circles a direction up to 10 as the path stays even.
- Add a second and third set per leg once one set feels controlled.
- Lean the torso further back or slow each circle to four seconds to increase the demand.
How Should You Program the Half Seated Leg Circle?
Use the half seated leg circle in a warm-up before squatting or hinging, or as filler between sets of heavy lower body work. It can be done daily. Perform 2 to 3 sets of 5 to 10 circles in each direction per leg, resting 30 to 45 seconds. Pair it with a hip flexor stretch or a glute bridge so the hip gets both range and strength.
