Setup
- Sit at the edge of a flat bench with your feet planted firmly on the floor for stability.
- Hold a dumbbell in each hand with a neutral grip (palms facing your torso).
- Bend your elbows to a 90-degree angle and keep them tucked close to your sides.
- Maintain a tall spine with your chest up and a very slight forward lean from the hips.
How to do it
- Exhale as you raise your elbows out to the sides until they are level with your shoulders, maintaining the 90-degree bend.
- Ensure your forearms remain parallel to the floor throughout the entire upward arc.
- Pause for a brief moment at the top to feel the contraction in the side of your shoulders.
- Inhale as you slowly lower the dumbbells back to the starting position using a controlled 3-second eccentric tempo.
Form checklist
- Keep your shoulders depressed (down) to prevent the upper traps from taking over.
- Do not allow the angle of your elbows to change during the movement.
- Avoid swinging your torso or using momentum to 'kick' the weights up.
- Stop the movement when your elbows reach shoulder height to avoid impingement.
Pro tips
- Think about pushing your elbows 'out' toward the walls rather than 'up' toward the ceiling to maximize lateral deltoid recruitment.
- Imagine you are holding a tray in each hand; keep the 'trays' level to ensure the lateral head of the delt is doing the work.
Make it harder
- Add a 2-second isometric hold at the top of every repetition to increase time under tension.
- Perform a '1.5 rep' style where you lift to the top, lower halfway, lift back to the top, and then lower all the way down.
