Exercise: the first prescription for Cubans of all ages.

Regular physical exercise improves quality of life and benefits the body's organs and systems: it tones and strengthens muscles; improves joint function; contributes to healthier heart and lungs; increases resistance to fatigue, and thus capacity for both physical and mental exertion; helps combat anxiety, depression and stress; improves sleep patterns; and is an important factor in maintaining healthy weight. It also provides a simple way of sharing with family and friends, even an opportunity for improving intergenerational communication and relations.
