Stability Ball Weighted Hyperextension

The weighted stability ball hyperextension is a hip-extension exercise performed face down over a stability ball while holding a weight close to the chest. It primarily strengthens the lower back, glutes, and hamstrings while challenging trunk control and balance. It can support posterior-chain strength and controlled spinal endurance.

Instructions

  1. Set up a stability ball on a non-slip surface and lie face down with the ball under your hips and lower abdomen. Brace your feet securely against a wall or place them wide on the floor.
  2. Hold a light weight plate against your chest with both hands. Let your upper body lower over the ball in a controlled manner, keeping your neck neutral.
  3. Exhale and extend at the hips, lifting your torso until it is roughly in line with your legs. Squeeze your glutes and keep your ribs down rather than excessively arching your lower back.
  4. Inhale as you slowly lower back to the starting position. Keep the ball stable, use a pain-free range of motion, and stop if you cannot maintain control.

Technique tips

  1. Start light. The unstable ball substantially increases the balance demand; progress the plate load only after your bodyweight control is consistent.
  2. Move from the hips. Think of lifting with your glutes rather than throwing your chest upward or cranking through the lower back.
  3. Control every repetition. Avoid bouncing on the ball, holding your breath, or using an end range that causes back discomfort.
