This version of a calf raise allows you to exercise each leg individually. This exercise is helpful to people who are rehabilitating from injury as it allows you flexibility with the weight.
Steps
Place a block on the floor about one foot in front of a bench.
Sit on the bench with a dumbbell across your upper thigh and the balls of one foot on the block.
Slowly raise and lower your toe up as high as possible without lifting your foot off the block.
