“The mobility and strength of yourcalf muscles are what sets the stage for how other parts, like your knees and hips, can move,” says Bowman. Strong calves can lead to longer strides, better balance, and strong ankles. With a wall or chair close by for balance, place a half foam roller (or a rolled yoga mat or towel) on the floor in front of you. Step onto the towel with a bare foot; place the ball of the foot on the top of the towel and keep your heel on the floor. This is your stretching leg. Slowly straighten your stretching leg. Keeping your body upright, step forward with the opposite foot. The tighter your stretching leg, the harder it is to take that step.
