Performing the: A Step-by-Step Tutorial Dumbbell Seated One Leg Calf Raise
Rest the dumbbell on your knee of the leg you want to exercise, holding it in place with your hand.
Slowly raise your heel as high as possible, making sure to flex your calf muscle at the top of the movement.
Hold this position for a second to maximize the contraction in the calf muscle.
Slowly lower your heel back to the starting position, ensuring a full range of motion, and repeat for the desired number of repetitions before switching to the other leg.
