Body composition refers to the proportion of fat, muscle and bone in one's body. Body composition goals refer to an individual’s aim or objective towards achieving a specific balance between these components for improved health, appearance, performance or other personal reasons. For example, someone may have a goal to increase their lean muscle mass while decreasing their overall fat percentage, or another person might want to maintain their current body composition with the addition of more muscle and less fat. Ultimately, body composition goals vary from one individual to another based on factors such as age, gender, genetics, health status, fitness level, and personal preferences.
