Sit on a bench or chair with your feet flat on the ground. Hold a dumbbell in one hand with an overhand grip, palm facing down. Rest your forearm on your thigh, with your wrist hanging off the edge. Slowly lower the dumbbell towards the ground by flexing your wrist. Pause for a moment at the bottom, then slowly curl your wrist back up towards your body. Repeat for the desired number of repetitions, then switch to the other arm.
