Standing Calf Raise

Stand on the foot block of a Standing Calf Raise machine on the balls of your feet and duck under the shoulder pads. You should have a comfortable separation between your feet and your toes should be pointing forward.
Start with your heels down as far as possible in a good stretch. Keep your knees straight and stiff but not locked. Rise up onto the balls of your feet and squeeze, moving only at the ankles.

Tips

If you don't have access to or don't wish to use a calf machine for various reasons, calf raises can be done freestanding on just about anything raised up (e.g. stairs, blocks, books, etc.) or even from the floor.
