Setup
- Stand with feet shoulder-width apart, holding a dumbbell in one hand with a neutral (hammer) grip.
- Position the dumbbell at your side with your arm fully extended and palm facing your thigh.
- Engage your core and maintain a slight bend in your knees to create a stable base.
How to do it
- Swing the dumbbell forward and upward in a controlled arc until it reaches shoulder height, keeping your arm straight throughout the movement.
- Exhale as you lift the weight, focusing on the tension in the front of your arm and shoulder.
- Inhale as you lower the dumbbell back to the starting position using a 2-second controlled eccentric phase.
- Complete all repetitions on one side before switching to the other to maintain constant tension.
Form checklist
- Keep the elbow locked in a nearly straight position; do not allow it to flex into a curl.
- Maintain a neutral spine and avoid leaning backward as the dumbbell rises.
- Keep your shoulder blade pinned down and back to prevent the trap from taking over.
- Ensure the movement comes from the shoulder joint rather than using momentum from the hips.
Pro tips
- Focus on 'reaching' the dumbbell toward the opposite wall to maximize the stretch and activation of the bicep's long head.
- Squeeze the dumbbell as hard as possible to increase neural drive and muscle fiber recruitment throughout the entire arm.
Make it harder
- Add a 2-second isometric hold at the top of the movement to eliminate all momentum.
- Perform the exercise while standing on the opposite leg to significantly increase the stability and core demand.
