Attention to both physical activity and nutrition are needed to stay healthy. The two factors work together and need to be in balance. In other words, calories taken in should equal energy used by our bodies. Being active increases the amount of calories you burn.

Some types of physical activity are especially good for us at any age: · Aerobic activities – These activities speed heart rate and breathing and improve heart and lung fitness. Examples are brisk walking, jogging, and swimming laps. · Resistance, strength building, and weight-bearing activities – help build and maintain bones and muscles by working them against gravity.

These activities help build and maintain muscles and bones. · Balance and stretching activities – enhance physical stability and flexibility, which reduces risk of injuries. Examples are gentle stretching, dancing, yoga, martial arts, and t'ai chi.
