Gaining body weight by adding muscle, body fat or both.

As in 'going for the burn' In endurance exercise, working muscles until lactic acid build-up causes burning sensation.

Compounds that contain carbon, hydrogen and oxygen used by the body as a fuel source. Two main groups are sugars and starch.

Carbohydrate Loading
Increase consumption of carbohydrates in liquid or food form normally three days prior to an endurance type event.

Cardiovascular Training
Physical conditioning that strengthens heart and blood vessels, the result of which is an increase in the ability for your body muscles to utilize fuel more effectively resulting in a greater level of exercising.

The breakdown of lean muscle mass, normally as a result of injury, immobilization and poor dieting techniques.

Indigestible fibre in foods.
