Your heredity influences your body composition, the size of your bones, and your muscle structure. Generally, you inherit a tendency toward one of three body builds. An ectomorph is a person who is long-boned and has a lean body build. A mesomorph is a person who has a muscular body build. An endomorph is a person who has a greater percentage of that tissues and a flabby appearance.
The type and frequency of exercise in which you engage also influences body composition. When you exercise to develop cardiovascular endurance and become physically fit, the ratio of fat tissue to lean tissue changes. As mentioned earlier, your percentage of fat tissue decreases and the percentage of lean tissue increases.
For exemple, marathon runners may have only eight to ten percent fat tissue Research indicates a relationship between susceptibility to heart disease and the area where fat accumulates. If you are wider in the abdomen than in the hips, you are more susceptible to heart disease than if the opposite is true.
