Group Workouts

Exercise reduces the amount of harmful cholesterol and fats in a person's blood. It increases the flexibility of the walls of blood vessels, and helps to lower blood pressure. This can reduce a person's risk for heart attack and stroke.

Working hard increases lung capacity, and their efficiency in moving air in and out of the body. As a result, more oxygen is drawn into the body and more carbon dioxide and other waste gases are expelled.

Just as muscles grow stronger when physically stressed, bones also respond by getting stronger. Exercise increases bone density, which helps prevent osteoporosis, a condition in which bones lose density, weaken, and become porous and fragile.

People who exercise regularly have lower incidences of cancer. The cancers most affected include colon, prostate, uterine, and breast cancers.
