The Weighted Pullover on a stability ball is an upper-body strength exercise that primarily targets the latissimus dorsi while recruiting the pectoralis major sternal head, teres major, deltoid posterior, and levator scapulae as synergists. Performing the movement on a stability ball instead of a flat bench increases the range of motion by allowing the torso to extend further, and demands continuous core engagement to maintain a stable bridge position throughout the arc.
How to do the Weighted Pullover (on stability ball)
- 1Place a stability ball on a non-slip mat and sit on it, then walk your feet forward until only your upper back and shoulders are resting on the ball, forming a bridge with your hips elevated and your body parallel to the floor.
- 2Plant your feet flat on the floor, hip-width apart, and squeeze your glutes to keep your hips raised at bench height throughout the set.
- 3Hold a dumbbell vertically by one end with both hands, or grip a weight plate with both palms pressing against it, and extend your arms directly above your chest with a slight bend at the elbows.
- 4Take a deep breath and brace your core to stabilize your torso on the ball.
- 5Slowly lower the weight in a wide arc overhead, allowing your arms to descend toward the floor behind your head while keeping the slight elbow bend constant.
- 6Continue lowering until you feel a strong stretch across your chest and lats, or until your upper arms are roughly in line with your torso — do not force range of motion past comfort.
- 7Exhale and drive the weight back up through the same arc, leading with your elbows, until the weight returns above your chest.
- 8Pause briefly at the top to reset your breath and brace, then repeat for the desired number of repetitions.
Form tips
- Keep your hips elevated in the bridge position for the entire set — letting the hips sag shifts the load away from the lats and increases strain on the lower back.
- Maintain a fixed, slight bend at the elbows throughout the arc; locking the elbows straight shifts stress to the elbow joint, while bending them too much turns the movement into a triceps exercise.
- Lower the weight under full control — the eccentric phase is where the latissimus dorsi and pectoralis major sternal head are stretched the most, so rushing through it reduces training stimulus.
- Keep your lower back from arching excessively as the weight descends overhead; a braced core and elevated hips naturally limit this, but watch for rib flare as a warning sign of too much load.
- Start lighter than you expect to need — the extended position places the shoulder in a vulnerable range, and control matters more than load on this exercise.
Common mistakes
- Letting the hips drop during the movement: sagging hips destabilize the ball, reduce core engagement, and shift mechanical stress away from the target muscles, making the exercise both less effective and harder to control.
- Using too much weight and losing elbow angle: heavy loads cause lifters to excessively bend the elbows to compensate, effectively turning the pullover into a partial triceps extension rather than a lat and chest stretch.
- Rushing through the eccentric phase: lowering the weight too quickly eliminates the muscle-lengthening tension that makes the pullover effective for developing the latissimus dorsi and pectoralis major sternal head.
- Forcing range of motion past comfortable depth: the shoulder is in an extended, externally rotated position at the bottom of the arc, and forcing additional depth places excessive stress on the anterior capsule and rotator cuff tendons.
- Positioning too far out on the ball so the head is unsupported: if the ball sits under the mid-back rather than the upper back and shoulders, the cervical spine hangs unsupported, increasing neck strain and reducing control of the movement.
Frequently asked questions
What muscles does the weighted pullover on a stability ball work?
The primary muscle targeted is the latissimus dorsi, which performs shoulder extension and adduction as the weight arcs from overhead back above the chest. Key synergists include the pectoralis major sternal head, teres major, deltoid posterior, and levator scapulae.
How is doing a pullover on a stability ball different from a flat bench?
The stability ball allows the torso to extend further into the arc as the weight descends overhead, increasing the stretch on the latissimus dorsi and pectoralis major sternal head beyond what a flat bench permits. The unstable surface also requires constant core and glute activation to hold the bridge position, making it more demanding overall.
Should I use a dumbbell or a weight plate for this exercise?
Both work well. A dumbbell held vertically by one end gives a comfortable grip and allows a natural wrist position. A weight plate gripped with both palms creates a wider hand position that some lifters find puts less stress on the wrists. Choose whichever allows you to maintain control through the full range of motion.
How many sets and reps should I do for the weighted pullover?
For lat and upper-body hypertrophy, 3–4 sets of 10–15 repetitions with a slow, controlled 2–3 second lowering phase is effective. Avoid training to failure due to the shoulder's vulnerable position at the bottom of the arc.
Is the weighted pullover on a stability ball safe for the shoulders?
For healthy shoulders the exercise is safe when performed with appropriate load and controlled technique. If you experience discomfort at the front of the shoulder at the bottom of the arc, reduce the range of motion or lighten the weight. Anyone with existing rotator cuff or shoulder impingement issues should consult a healthcare professional before including overhead-arc exercises in their programming.
