Setup
- Lie on your side on a flat bench with your legs stacked or staggered for stability.
- Hold a dumbbell in your top hand with a neutral grip, resting it against your outer thigh.
- Support your head with your bottom arm or rest it on the bench.
- Keep a slight, fixed bend in your elbow throughout the setup.
How to do it
- Exhale as you raise the dumbbell in a wide arc until your arm is perpendicular to your torso.
- Maintain a controlled tempo, taking approximately 2 seconds to reach the top position.
- Inhale as you slowly lower the dumbbell back toward your hip, stopping just before it touches your leg.
- Complete the full set on one side before switching to the opposite arm.
Form checklist
- Keep your torso still; do not rock your body to gain momentum.
- Ensure the movement occurs only at the shoulder joint.
- Keep your palm facing down or slightly forward at the top of the movement.
- Maintain a slight bend in the elbow to protect the joint.
Pro tips
- Think about 'reaching' the dumbbell toward the far wall to maximize lateral deltoid engagement.
- Focus on the bottom third of the movement, as this is where the tension is highest compared to standing variations.
Make it harder
- Incorporate a 3-second eccentric (lowering) phase to increase time under tension.
- Pause for 1 second at the peak of the movement to challenge the rotator cuff and deltoid stability.
