Starting Position: Grasp a dumbbell in each hand. Standing with the back straight, turn the dumbbells so they are facing the body.
Performing The Exercise: Curl them upward, keeping the thumb on top, and the palms facing the midline. Curl it to the fully contracted position and slowly lower it to the starting position, then repeat.
Tips: Standing against a wall or sitting in a seat with a back on it can help keep the back straight and reduce upper body swing often encountered with curls. Keep the wrist in the same position throughout the movement.
