Dumbbell reverse wrist curl

Sit on a bench or chair with your feet flat on the ground. Hold a dumbbell in each hand with an overhand grip, palms facing down. Rest your forearms on your thighs, allowing your wrists to hang off the edge. Slowly curl your wrists upward, bringing the dumbbells towards your body. Pause for a moment at the top, then slowly lower the dumbbells back down to the starting position. Repeat for the desired number of repetitions.
