Setup
- Kneel on the floor and lean your torso over the stability ball, positioning your lower abdomen and pelvis against the center of the ball.
- Extend your legs straight behind you with your toes tucked into the floor for stability, or brace your feet against a wall for extra support.
- Place your hands lightly behind your head, across your chest, or resting on the ball for balance.
- Engage your core and tuck your chin slightly to maintain a neutral cervical spine.
How to do it
- Inhale and slowly lower your upper body over the curve of the ball, allowing your spine to round slightly to follow the ball's contour.
- Exhale as you engage your lower back muscles to lift your torso until your body forms a straight line from your head to your heels.
- Pause for one second at the top of the movement, focusing on the contraction in the erector spinae.
- Lower your torso back down with a controlled 2-3 second tempo to the starting position.
Form checklist
- Keep your neck neutral by looking at the floor throughout the entire movement.
- Avoid hyperextending or arching your back past a straight line at the top.
- Keep your glutes and hamstrings engaged to stabilize your lower body.
- Ensure the movement is driven by your lower back, not by pushing off the ball with your hands.
Pro tips
- Focus on 'peeling' your chest off the ball one vertebra at a time to maximize the mind-muscle connection with the spinal erectors.
- Squeeze your glutes hard at the peak of the movement to provide a stable base for the pelvis and protect the lumbar spine.
Make it harder
- Hold a light weight plate or dumbbell against your chest to increase resistance.
- Extend your arms straight overhead in a 'Y' position to increase the lever arm and difficulty.
