Setup
- Sit on the stability ball and safely transition into a bridge by walking your feet forward until your upper back and neck are supported by the ball.
- Position your feet hip-width apart with knees bent at 90 degrees, driving your hips up until your torso is parallel to the floor.
- Grasp the barbell with an overhand grip slightly wider than shoulder-width, holding it directly over your mid-chest.
- Retract your shoulder blades into the ball to create a stable pressing platform.
How to do it
- Inhale and slowly lower the barbell toward your lower chest, keeping your elbows tucked at a 45-degree angle from your torso.
- Exhale as you press the bar back to the starting position by extending your arms and squeezing your chest muscles.
- Maintain a controlled 2-1-1-0 tempo, emphasizing the eccentric (lowering) phase to manage the instability.
- Keep your glutes and core braced throughout the entire set to prevent the hips from sagging or the ball from rolling.
Form checklist
- Keep your hips high and level with your shoulders throughout the movement.
- Ensure your head and neck are fully supported by the ball to avoid strain.
- Maintain vertical forearms at the bottom of the movement.
- Keep your feet flat on the floor and drive through your heels for stability.
Pro tips
- Actively squeeze the glutes to create a 'human bridge,' which provides a more rigid surface for the upper body to press from.
- Focus on pulling the bar down toward you to engage the lats, which helps stabilize the shoulder joint on the ball.
- If balance is an issue, start with a wider foot stance and gradually narrow it as your stability improves.
Make it harder
- Narrow your foot stance to a close-grip width to significantly increase the demand on your core stabilizers.
- Add a 3-second pause at the bottom of the rep to remove all elastic energy and force a more powerful concentric drive.
