Background

Weightlifting, also known as bodybuilding, is a form of exercise that results in muscular endurance and strength.

Most weight training involves isotonic exercises. Isotonic muscle training involves contractions where tension is equal throughout the range of motion. Isometric muscle training involves the contraction of a muscle against an immovable force. Isokinetic muscle training is a type of contraction where the speed of movement is fixed and resistance varies with the force exerted.

Bodybuilding and weightlifting are not interchangeable terms. Bodybuilders focus on gaining bulk and increasing the size of muscles while weightlifters focus on the strength and power of the muscles.
