SINGLE-LEG CALF RAISE

Because your calves hold up most of your weight, they deserve some attention. This exercise helps develop the soleus and gastrocnemius muscles—critical for walking, running, and jumping because they pull the heels up for forward movement.

1 Stand with your left foot flat on the floor and bend your right knee to form a 90-degree angle with your right leg. Relax your arms at your sides.

2 Lift your left heel off the floor and push up from the ball of your left foot to elevate your body. Pause, then lower your left heel to the floor. Repeat this step 8 to 10 times. Repeat these steps with your right foot flat on the floor and your left leg bent.
