The dumbbell standing calf raise is a simple loaded calf exercise you can do anywhere with a pair of dumbbells. Rising onto the balls of your feet against the extra load works the gastrocnemius, the larger visible calf muscle. Doing it on a step or plate adds a stretch at the bottom and makes the exercise far more effective.
