Walking is effective cardiovascular exercise. Walking for fitness requires no additional equipment, and can be done right from your front door.
Ramp up your walking for fitness workout by adding in a few exercises at regular intervals:
Heel Raises: Stand keeping your torso straight. Lift and lower your heels.
Toe Raises: Stand keeping your torso straight. Lift and lower your toes.
Squats: Stand with your feet hip width apart. Bending from your knees and hips, sit back and lower your body toward the ground about six inches. Stand back up to return to your starting position.
*Always consult your physician before beginning exercise.
