Equipment

  • Barbell
  • Weight plate

Setup

  1. 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.
  2. Position your feet hip-width apart with knees bent at 90 degrees, driving your hips up until your torso is parallel to the floor.
  3. Grasp the barbell with an overhand grip slightly wider than shoulder-width, holding it directly over your mid-chest.
  4. Retract your shoulder blades into the ball to create a stable pressing platform.

How to do it

  1. Inhale and slowly lower the barbell toward your lower chest, keeping your elbows tucked at a 45-degree angle from your torso.
  2. Exhale as you press the bar back to the starting position by extending your arms and squeezing your chest muscles.
  3. Maintain a controlled 2-1-1-0 tempo, emphasizing the eccentric (lowering) phase to manage the instability.
  4. 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.
