The bodyweight floor calf raise is the simplest calf exercise you can do, and no equipment is required.
- Stand with your feet around shoulder width apart close to something you can hold onto for balance (if needed).
- Take your heels slightly off the floor. This is the starting position for the exercise.
- Slowly raise your heels up as far as possible.
- Pause and squeeze the calves, and then lower yourself back down to the starting position.
- Don't let your heels rest on the floor! Repeat for desired reps.
