Standing Straight Leg Hamstring Contract Relax On Exercise Ball
Standing Straight Leg Hamstring Contract Relax On Exercise Ball Exercise Description
Standing Straight Leg Hamstring Contract-Relax on Exercise Ball is a PNF-style hamstring stretch performed in standing with the heel supported on a stability ball. The primary target is the hamstring group (semitendinosus, semimembranosus, biceps femoris) through a hip-hinge pattern with a neutral spine. You create an isometric hamstring contraction against the ball, then relax and gently increase hip flexion to deepen the stretch. Core and glute musculature stabilize the pelvis and trunk, while ankle position can increase or decrease calf tension (toes up increases gastrocnemius stretch). The ball introduces a mild balance demand; use a wall or stable support as needed for control and alignment.

How To Do The Standing Straight Leg Hamstring Contract Relax On Exercise Ball Exercise
‘- Position the ball in front of you. Stand tall, feet hip-width, ribs stacked over pelvis, shoulders relaxed.
– Place the working heel on the top of the ball. Knee straight but not locked; toes point up; hips square to the ball.
– Shift weight into the stance leg. Set a neutral spine and level pelvis; eyes forward.
– Hinge at the hips (not the low back) until you feel a mild hamstring stretch. Keep the chest long and shoulder blades gently retracted.
– Contract phase: without letting the ball roll, press the heel down/back into the ball to engage the hamstrings isometrically. Maintain steady breathing and posture.
– Relax phase: release the contraction, then hinge a small amount further while keeping the spine neutral and pelvis level.
– Keep the kneecap and toes of the elevated leg pointing straight up; avoid external rotation. Track the stance-knee over the toes.
– Adjust intensity by moving closer/farther from the ball or by ankle position (more dorsiflexion = stronger stretch).
– For added stability, lightly hold a wall or place the ball against a wall to limit rolling.
– Step down with control and repeat on the other side.
Standing Straight Leg Hamstring Contract Relax On Exercise Ball Tips
‘- Stand tall with ribs stacked over pelvis and shoulders relaxed before placing your heel on the ball.
– Keep the working knee straight but not locked, with toes and kneecap pointing straight up.
– Square your hips to the ball and keep the pelvis level as you move.
– Shift weight into the stance leg and maintain a neutral spine with eyes looking forward.
– Hinge from the hips (not the low back), keeping the chest long and shoulder blades gently retracted.
– During the contract phase, press the heel down/back into the ball without letting the ball roll.
– Maintain steady breathing and upright posture while you create the isometric hamstring contraction.
– In the relax phase, release the contraction and hinge only a small amount further while keeping the spine neutral.
– Track the stance-knee over the toes and adjust intensity by ankle position (more dorsiflexion for a stronger stretch).
– Use a wall or place the ball against a wall for added stability and control if needed.
Standing Straight Leg Hamstring Contract Relax On Exercise Ball Beginner Introduction
Standing Straight Leg Hamstring Contract-Relax on Exercise Ball is a standing stretch that blends muscle activation and relaxation for the back of the thigh. One heel rests on a stability ball while the other leg supports the body, creating a gentle challenge for balance. The main sensation centers on the hamstrings, with help from the glutes and core to steady the hips and torso. Depending on how the ankle is positioned, the stretch can also reach into the calf, especially when the toes are drawn upward.
The movement centers on hinging from the hips rather than rounding through the lower back, so the spine stays long as the body leans forward over the lifted leg. A contract-relax pattern is used: the heel lightly presses into the ball without visible motion, then the effort eases off and the body sinks a bit deeper. The supporting leg carries most of the weight, with the knee roughly aligned over the toes. Many people set up near a wall or place the ball so it cannot roll much, adding a sense of security while working on control and alignment.
