Dumbbell One Arm Hammer Press on Exercise Ball

Setup

1. 01Sit on an exercise ball with a dumbbell and walk the feet forward until the upper back rests on the ball.
2. 02Set the hips up in a bridge so the torso is roughly parallel to the floor.
3. 03Hold the dumbbell over the chest with a neutral grip, palm facing the midline.
4. 04Extend the free arm out to the side or on the hip for balance.

Execution

1. 01Lower the dumbbell toward the chest with the elbow tucked near the ribs.
2. 02Resist the pull to rotate toward the loaded side.
3. 03Press the dumbbell back to lockout over the shoulder.
4. 04Keep the hips level and bridged for the entire set.

Checkpoints

• -Hips stay high and square; no sagging or twisting.
• -The elbow tracks close to the body with the neutral grip.
• -The dumbbell finishes stacked over the shoulder joint.
• -Head and upper back stay supported on the ball.

Common mistakes

• -Letting the loaded side of the torso dip or rotate.
• -Dropping the hips and losing the bridge.
• -Flaring the elbow wide and losing the hammer-press line.
• -Going so heavy the ball position cannot be held still.
