Weighted Hyperextension On Stability Ball
- Intermediate
- Compound
- Rep-based
- Back
- Waist
This compound movement strengthens the entire posterior chain, specifically the erector spinae, glutes, and hamstrings, while the stability ball adds an element of core instability. Incorporating a weight plate increases the load on the spinal extensors, promoting better posture and lower back resilience.

Setup
- Place the stability ball near a wall and position your feet firmly against the base of the wall for support.
- Lie prone with your hips and lower abdomen centered on the ball, legs extended straight behind you.
- Hold a weight plate securely against your chest, crossing your arms over it to keep it in place.
- Set your feet hip-width or slightly wider to establish a stable base of support.
How to do it
- Inhale and slowly lower your torso over the curve of the ball by hinging at the hips, maintaining a flat back.
- Exhale as you engage your glutes and lower back to lift your torso until your body forms a straight line from head to heels.
- Pause for one second at the top of the movement to maximize muscle tension.
- Lower back down with a controlled 2-3 second tempo, avoiding any bouncing or momentum.
Form checklist
- Keep your chin tucked and neck neutral to avoid straining the cervical spine.
- Stop when your torso is parallel with your legs; do not arch your back past a straight line.
- Ensure the weight plate remains tight against your chest throughout the entire set.
- Keep your legs fully extended and squeeze your glutes at the peak of the movement.
Pro tips
- To shift more focus to the glutes and hamstrings, slightly round your upper back and focus purely on the hip hinge.
- Visualize 'peeling' your chest away from the ball to engage the erector spinae through their full range of motion.
Make it harder
- Hold the weight plate at arm's length in front of you to increase the lever arm and difficulty.
- Incorporate a 3-second isometric hold at the top of each repetition.
