Standing calf raises are a simple yet effective exercise for strengthening the muscles in your calves and improving ankle stability. This exercise can be performed while standing with the support of a chair or countertop for balance.
Stand with your feet hip-width apart, and hold onto a chair or countertop for support. Rise onto the balls of your feet, lifting your heels off the ground as high as comfortable. Hold the raised position for a few seconds, then lower your heels. Repeat for two to three sets of 10 to 15 repetitions.
