Half Frog Stretch
Half Frog Stretch Exercise Description
The Half Frog Stretch is a floor-based hip mobility drill that targets the inner‑thigh adductors while keeping the spine neutral and the pelvis level. Performed from a quadruped position, one leg moves into a “frog” shape—hip abducted with the knee flexed about 90 degrees and the lower leg resting on the floor—while the opposite knee stays under the hip for support. This unilateral setup lets you fine‑tune angles to find a comfortable, controlled stretch without stressing the lower back. Expect the primary sensation along the groin/inner thigh of the “frog” side as the hips shift gently backward. Focus on steady breathing, a mild stretch intensity, and precise alignment of knee, hip, and ankle to protect the joints and emphasize the adductors.

How To Do The Half Frog Stretch Exercise
‘- Set up on a padded surface on forearms and knees; shoulders stacked over elbows, support knee under the hip.
– Slide the working knee out to the side in line with the hip; bend that knee to ~90°, shin and inside edge of foot on the floor.
– Keep pelvis level and square; brace lightly so the lumbar spine stays neutral (avoid sagging or arching).
– Point the working toes outward in line with the shin; keep the knee, ankle, and hip on the same plane.
– Gently shift your hips backward until you feel a comfortable stretch along the inner thigh of the working side; no sharp pain.
– Keep the support leg vertical under the hip; avoid letting it slide or rotate.
– Maintain slow, even breaths; soften the ribs and keep neck and shoulders relaxed.
– To exit, shift hips forward, bring the working knee back under you, and return to quadruped.
Half Frog Stretch Tips
‘- Set up on forearms and knees with shoulders stacked over elbows and the support knee directly under the hip.
– Slide the working knee straight out to the side in line with the hip before bending it to about 90°.
– Rest the working shin and the inside edge of the foot flat on the floor.
– Keep the pelvis level and square as you move; avoid letting one hip drop or twist.
– Brace lightly through the torso to keep the lumbar spine neutral, avoiding sagging or arching.
– Point the working toes outward in line with the shin so the knee, ankle, and hip stay on the same plane.
– Gently shift the hips backward only until you feel a comfortable inner‑thigh stretch, not sharp pain.
– Keep the support leg vertical under the hip and prevent it from sliding or rotating.
– Maintain slow, even breathing while softening the ribs and relaxing the neck and shoulders.
– To finish, shift the hips forward, bring the working knee back under you, and return to quadruped.
Half Frog Stretch Beginner Introduction
The Half Frog Stretch is a ground-based hip mobility exercise that places attention on the inner thigh and groin of one leg while the back stays calm and supported. It starts from a bent‑limb, hands‑free base on the floor, where the body is propped on the forearms and knees. One leg moves outward into a “frog‑like” shape with the knee bent around a right angle and the lower leg resting on the surface, while the other leg stays more underneath the body to provide stability.
This one‑sided setup allows small adjustments in leg position so the stretch can feel gentle and manageable rather than intense or jarring, with the lower back protected throughout. Sensation is usually felt along the inner thigh of the outward leg as the hips drift slightly backward. The movement emphasizes calm, steady breathing, light tension through the middle of the body, and careful alignment between hip, knee, and ankle so the joints feel supported while the inner thigh gradually lengthens.
