Exercise Ball One Legged Diagonal Kick Hamstring Curl
Exercise Ball One Legged Diagonal Kick Hamstring Curl Exercise Description
The Exercise Ball One-Leg Hamstring Curl is a unilateral posterior-chain movement performed in a bridge position with one foot on a stability ball. It primarily targets the hamstrings (knee flexion) and gluteus maximus (hip extension), while the abdominals and obliques brace isometrically to maintain a neutral spine and level pelvis. Because the surface is unstable, the hip abductors/adductors and deep core contribute to frontal-plane and anti-rotation control. The raised, nonworking leg stays straight to increase lumbopelvic stability demands without loading the spine. Expect a controlled pull-in and return, emphasizing alignment over range.

How To Do The Exercise Ball One Legged Diagonal Kick Hamstring Curl Exercise
‘- Lie supine with arms about 30–45° from your sides, palms down.
– Place one heel–midfoot on the center of the ball; dorsiflex that ankle (toes toward shin).
– Lift the other leg straight up in line with its hip; keep knee extended and foot relaxed.
– Brace your core; lightly tuck ribs toward hips to set a neutral spine.
– Drive through the heel on the ball to raise hips until shoulders–hips–heel form a straight line; keep pelvis level.
– Without letting hips drop or rotate, exhale and curl the ball toward you by flexing the working knee.
– Pause briefly when the knee reaches roughly 90°, maintaining hip extension.
– Inhale and slowly extend the knee to roll the ball back to the start, keeping hips up and spine neutral.
– Lower hips to the floor with control, reset, and switch legs.
– Keep gaze up, neck long; avoid pushing through the arms, arching the low back, or letting the knee collapse inward.
Exercise Ball One Legged Diagonal Kick Hamstring Curl Tips
‘- Set your arms about 30–45° from your sides with palms down.
– Place your working heel–midfoot on the center of the ball and keep the ankle dorsiflexed (toes toward your shin).
– Lift the nonworking leg straight up in line with its hip, keeping the knee extended and the foot relaxed.
– Brace your core and lightly tuck your ribs toward your hips to set and maintain a neutral spine.
– As you bridge up, drive through the heel on the ball until your shoulders, hips, and heel form a straight line, keeping your pelvis level.
– While curling the ball in, prevent your hips from dropping or rotating and pause briefly when the working knee is around 90°, maintaining hip extension.
– As you roll the ball back out, inhale and slowly extend the knee while keeping your hips up and spine neutral.
– Lower your hips to the floor with control before resetting or switching legs.
– Keep your gaze up and neck long, and avoid pushing through your arms, arching your low back, or letting the working knee collapse inward.
Exercise Ball One Legged Diagonal Kick Hamstring Curl Beginner Introduction
The Exercise Ball One-Leg Hamstring Curl blends single-leg strength work with full-body stability. This floor-based bridge variation uses a stability ball under one foot while the other leg stays lifted, so the working side handles the effort of bending the knee and lifting the hips. The movement mainly challenges the hamstrings and glutes, while the abs and side abs tighten to support the lower back. Muscles around the hips and inner thighs assist with balance, especially as the ball shifts beneath the foot.
Because only one leg contacts an unstable surface, the body must resist tipping or twisting as the ball rolls in and out. The raised leg remains straight, increasing the demand on the mid-section without extra load on the spine. The overall feel is slow and controlled, with an emphasis on smooth alignment rather than how far the ball travels. This creates a demanding, stability-focused option for building back-of-leg strength while training body awareness and control.
