Arms
Dumbbell
1. Stand holding a dumbbell in each hand with an underhand grip (palms facing forward). Keeping your upper arms stationary, curl the weights up towards your shoulders. 2. At the top of the movement, pause and rotate your wrists 180 degrees so that your palms now face forward (overhand grip). 3. Slowly lower the dumbbells back to the starting position using this overhand grip. Once at the bottom, rotate your wrists back to the initial underhand grip to begin the next rep.
