Ankle Circles
Starting position:
Stand upright, feet in a shoulder-width stance, hands on your hips.
Exercise:
Raise your leg by flexing your hip and knee upwards. Make sure that you are not bending your hip and knee to more than a 90-degree angle.
Stand on one leg and rotate the ankle of your raised leg. Repeat rotation several times to each side by alternating your legs.
Note:
Make sure you have the correct angle in both joints.
Stand upright with your torso straight.
Recommendation:
Exercising in front of the mirror will allow you to check for correct motion.

While obviously not a mass builder, this is a perfect exercise for the beginning of calf workout. It is also well suited for people recovering from calf injury.
