Setup
- Set an incline bench to an angle between 45 and 60 degrees.
- Lie sideways against the bench with your non-working side pressed against the backrest.
- Hold a dumbbell in your outer hand with a neutral grip (palm facing your thigh).
- Plant your feet firmly on the floor and use your bottom arm to stabilize your torso against the bench.
How to do it
- Start with the dumbbell hanging straight down, keeping a slight bend in your elbow.
- Exhale and raise the dumbbell out to the side in a wide arc until your arm is parallel to the floor.
- Pause for a moment at the top of the movement to maximize the contraction in the lateral deltoid.
- Inhale and slowly lower the dumbbell back to the starting position over a 2-3 second count.
Form checklist
- Keep your torso stationary and avoid using momentum to swing the weight.
- Maintain a consistent, slight bend in the elbow throughout the entire set.
- Ensure your wrist stays straight and does not lead the movement.
- Keep your chest pressed against the bench to prevent the torso from rotating backward.
Pro tips
- Think about 'pushing' the dumbbell away toward the wall rather than just lifting it up to better engage the lateral head.
- Stop the descent just before the dumbbell touches your leg to maintain constant tension on the muscle fibers.
Make it harder
- Incorporate a 2-second isometric hold at the peak of each repetition.
- Slow down the eccentric phase to 4 seconds to increase time under tension.
