dumbbell single leg calf raise

Stand on the edge of a step or platform with your heels hanging off and your toes on the step.

Hold a dumbbell in one hand and place your other hand on a wall or railing for support.

Raise your heel as high as possible, lifting your body up onto your toes.

Pause for a moment at the top, then slowly lower your heel back down below the step.

Repeat for the desired number of repetitions, then switch to the other leg.
