Setup
- Sit on a bench with back support, holding a dumbbell in each hand.
- Position the dumbbells at shoulder height in front of your chest with your palms facing your body.
- Keep your elbows tucked in close to your torso and your feet planted firmly on the floor.
- Engage your core and maintain a neutral spine against the backrest.
How to do it
- Press the dumbbells upward while simultaneously rotating your palms outward so they face forward at the top of the movement.
- Exhale as you reach full extension overhead, ensuring you do not lock your elbows completely.
- Inhale as you lower the weights back to the starting position, rotating your palms back toward your face in a controlled manner.
- Maintain a steady tempo, taking approximately 2 seconds to press up and 2 seconds to lower down.
Form checklist
- Keep your lower back pressed against the bench to prevent arching.
- Ensure the rotation is fluid and occurs throughout the entire pressing motion.
- Avoid clinking the dumbbells together at the top of the rep.
- Keep your wrists stacked directly over your elbows during the middle of the press.
- Do not let your elbows flare out too wide during the initial phase of the lift.
Pro tips
- Focus on a 'scooping' motion during the first half of the rep to maximize anterior deltoid recruitment.
- Pause for a split second at the bottom with palms facing you to eliminate momentum and increase mechanical tension.
Make it harder
- Perform the exercise standing to significantly increase the demand on your core and spinal stabilizers.
- Implement a 3-second eccentric (lowering) phase to maximize muscle fiber breakdown and hypertrophy.
