If you struggle with ankle stability, add these ankle-strengthening exercises to your routine. To be clear, these exercises won't improve your balance, but they will increase the strength of the muscles around the foot and ankle so that they can have a more robust response when you stray from your center of gravity. Start with 3 sets of 10 reps of each exercise except the calf raise. Begin with 15 - 20 calf raises and perform exercises two to three times per week.
