Weighted Single-Leg Calf Raise

How to do it

1. Stand on the ball of one foot on a step, with the heel hanging off the edge.
2. Hold a dumbbell or kettlebell in the hand on the same side as the working leg.
3. Hold a wall with the other hand for balance.
4. Rise as high as you can onto the ball of the foot and pause briefly at the top.
5. Lower the heel slowly below the step until the calf is fully stretched.
6. Complete all reps on one leg, then switch sides.
