Step by Step Guide
Begin standing with all of your weight on one leg. Lift the other leg off the ground and hover it in the air a few inches off the ground. Hold onto a wall, countertop, or chair in front of you, if desired.
Raise up onto your toes as you lift the heel as high as possible.
Then, lower your heel back down.
Repeat for the desired repetitions, on both legs.
A common mistake is not going up high enough onto your toes. So as you raise up, shift the weight into your big toe a little more. And rise up as high as you possibly can to strengthen those calves through a larger range of motion.
