1
Stand upright with feet shoulder-width apart, holding a dumbbell in each hand with arms extended at your sides, palms facing forward, shoulders relaxed and back straight.
2
Maintain a neutral spine with core engaged. Position dumbbells at arm's length with elbows tucked close to the torso, ensuring a firm grip with palms facing forward throughout the movement.
3
Slowly lower the dumbbells back down to the starting position by extending the elbows, controlling the weight throughout the descent with a 2-3 second eccentric phase, keeping elbows stationary.
4
Curl both dumbbells upward in a controlled arc by flexing the elbows, bringing the weights toward the shoulders while keeping upper arms stationary. Squeeze the biceps at the top position before beginning the eccentric phase.
