Anabolic Steroids - Prescription drugs that mimic male hormones, but without most of the androgenic side effects of actual testosterone. Many bodybuilders use these dangerous drugs to help increase muscle mass and strength, even though possession of them is now a felony in most states.
Basal Metabolic Rate (BMR) - Your body mass ratio, or the speed at which your resting body burns calories to provide for its basic survival needs. You can elevate your BMR and more easily achieve lean body mass through consistent exercise, and particularly through aerobic workouts.
Glycogen - Blood sugar stored in the muscles, liver, and to a lesser extent the bloodstream. Glycogen helps to fuel muscle contractions.
