This plan has three different types of exercise: aerobic activity or cardio (walking), strength or resistance training (weights), and flexibility training (yoga). And all of them are important.
Walking and other cardio workouts like jogging, cycling, swimming, and tennis boost the power of your heart and lungs. Weight lifting builds muscle, keeps your bones strong, and helps with balance and coordination. Yoga can increase your range of motion and lower your chances of getting injured.
