Bodyweight Single Leg Kas Glute Bridge
Bodyweight Single Leg Kas Glute Bridge Exercise Description
The Bodyweight Single-Leg Kas Glute Bridge is a controlled, top-range hip extension drill performed on the floor to emphasize the gluteus maximus while limiting lumbar motion. Working unilaterally increases the demand on the gluteus medius/minimus to keep the pelvis level, with hamstrings assisting and the trunk musculature bracing for lumbopelvic stability. The “Kas” style uses a shortened range around lockout (the upper third of the bridge) to maintain constant tension and refine end‑range hip extension control. Expect a strong contraction high in the glutes, with the ribs “down” and a slight posterior pelvic tilt to avoid compensatory lower‑back arching. This variation is useful for practicing clean hip extension mechanics, knee‑over‑midfoot alignment, and even pressure through heel and midfoot on the working leg.

How To Do The Bodyweight Single Leg Kas Glute Bridge Exercise
‘- Lie supine with knees bent and feet hip‑width; arms at ~30–45° with palms down for light support. Eyes to ceiling, chin slightly tucked.
– Set the working foot so the shin will be roughly vertical at the top; keep the whole foot on the floor (heel and midfoot loaded).
– Brace your abdominal wall; bring ribs down and gently posteriorly tilt the pelvis (flatten the low back to the floor).
– Lift the non‑working leg so the thigh is toward the chest (about hip‑flexed), keeping the pelvis level.
– Dorsiflex the working foot; align the knee over the second/third toe.
– Drive through the planted heel to raise the hips until the working hip reaches neutral extension; stop before the low back arches.
– Perform small, controlled moves in the top third of the range: lower a few centimeters, then re‑extend through the hip.
– Keep pelvis square, ribs down, and posterior tilt maintained; motion comes from the hip, not the lumbar spine.
– Maintain even foot pressure and a vertical shin at the top; avoid knee collapse inward or outward.
– Lower with control, set the non‑working foot down, and switch sides when finished.
Bodyweight Single Leg Kas Glute Bridge Tips
‘- Set your working foot so the shin is vertical at the top position.
– Keep the whole working foot on the floor, with heel and midfoot loaded.
– Brace your abdominal wall and bring the ribs “down” before you lift.
– Gently posteriorly tilt the pelvis to flatten the low back to the floor.
– Lift the non‑working leg so the thigh moves toward the chest while keeping the pelvis level.
– Dorsiflex the working foot and align the knee over the second/third toe.
– Drive through the planted heel to raise the hips only until the working hip reaches neutral extension.
– Perform small, controlled moves in the top third of the range, lowering just a few centimeters before re‑extending.
– Keep the pelvis square, ribs down, and posterior tilt maintained so motion comes from the hip, not the lumbar spine.
– Maintain even foot pressure and a vertical shin at the top, avoiding the knee collapsing inward or outward.
Bodyweight Single Leg Kas Glute Bridge Beginner Introduction
The Bodyweight Single-Leg Kas Glute Bridge is a floor-based bridge variation that highlights the top portion of hip lifting. Instead of moving through a long arc, the action centers on small pulses near the highest point, where the main glute muscle works hardest. Because only one leg supports the body, the side and deep glutes around the hip are drawn in to help keep the hips from tipping, while the hamstrings and core contribute to overall steadiness.
This bridge style emphasizes smooth control at the end of hip extension rather than big, explosive reps. Attention stays on firm tension high in the glutes, limited motion through the lower back, and a gentle tuck of the hips so the spine stays quiet. The position also encourages steady pressure through the heel and middle of the working foot, with the knee roughly stacked over the middle toes. This makes the movement useful for building awareness of clean hip drive, stable hips and trunk, and consistent leg alignment.
