Dumbbell Standing Arms Rotate

Muscles worked

Setup

1. Stand with feet shoulder-width apart and hold a light dumbbell in each hand.
2. Raise your upper arms out to your sides until they are parallel to the floor, with elbows bent at a 90-degree angle.
3. Position your forearms parallel to the floor with palms facing down, creating a 'goalpost' shape.

How to do it

1. Rotate your shoulders to lift the dumbbells upward until your forearms are vertical, exhaling as you move.
2. Squeeze your shoulder blades together at the top of the rotation for a brief pause.
3. Inhale as you slowly lower the dumbbells back to the starting position (forearms parallel to the floor) using a controlled 3-second tempo.

Form checklist

• Keep your elbows aligned with your shoulders; do not let them drop toward your ribs.
• Maintain a strict 90-degree bend in the elbows throughout the entire set.
• Keep your neck relaxed and avoid shrugging your shoulders toward your ears.
• Ensure your wrists remain neutral and do not bend backward or forward.
• Keep your core engaged to prevent your lower back from arching.

Pro tips

• Focus on the 'pivot' point at the shoulder joint; imagine your upper arm is a fixed rod rotating on a single axis.
• Use very light weights to ensure the small rotator cuff muscles are doing the work rather than the larger primary movers like the lats or traps.

Make it harder

• Add a 3-second isometric hold at the top of the movement to increase time under tension for the rear deltoids.
• Perform the exercise while standing on one leg to challenge your core stability and balance.
