Glossary of Bodybuilding Terms

Quadriceps  – The quadriceps, normally called the “quads,” are the large, four-headed muscles located on the front and sides of the upper legs. They are analogous to the triceps, and are the extensors of the legs. Their primary function is to extend the lower leg forward (bringing the upper and lower legs to a lock-out configuration).

Quads — A slang term referring to the quadriceps muscles on the front thigh.

Range of motion (ROM) — The range through which a joint can be moved, usually its range of flexion and extension. Exercises also have a specific range of motion that involves the movement from start to finish.

Regimen – A regulated course of exercise and diet designed to produce a pre-determined result.

Rep — Slang term for repetition.

Repetition — Refers to a single execution of an exercise. For example, if you curl a barbell through the entire range of motion once from start to finish, you have completed one repetition (rep) of the movement.

Repetition speed — The length of time it takes to complete one rep.

Resistance — The amount of weight used in an exercise. Sometimes referred to as intensity.

Resistance training – Any type of training in which your muscles work against a resistance; the resistance may be provided by a weight, an elastic or rubber band, or your own body weight.

Resting metabolic rate (RMR) — The metabolic rate measured under conditions of rest. This is the minimal number of calories a person will need during a day to maintain body weight.

Rest interval — The brief pause lasting between 30 seconds and 2 minutes, and in some cases even longer, which occurs between sets to allow the body to partially recuperate before initiating the succeeding set.

Rest-Pause – A training technique in which the user completes one set, and then rests only about 10 seconds before starting the next set. The technique is based on the biological fact that a muscle recovers about 90 percent of its strength within 10 to 15 seconds. Rest-pause allows the bodybuilder to use heavy weight for every set.

Ripped — A term that means a body has clearly visible muscles and very little fat.

Rotator cuff – The four muscles – the supraspinatus, infraspinatus, teres minor, and subscapularis – and their associated tendons that hold your humerus (the long bone of your upper arm) in place in your shoulder joint and enable your arm to rotate. Rotator cuff injuries are common in sports that involve throwing motions.

RMR — See resting metabolic rate.

Routine — A term that refers to an individual training program.
