dumbbell seated calf raise

Sit on a bench or chair with your feet flat on the ground and a dumbbell resting on your thighs. Place the balls of your feet on a raised surface such as a step or block, with your heels hanging off the edge. Hold onto the dumbbell for stability. Raise your heels as high as possible, lifting your body weight onto the balls of your feet. Pause for a moment at the top, then slowly lower your heels back down to the starting position. Repeat for the desired number of repetitions.
