Weightlifters are a completely different kind of athlete. While the goal of the bodybuilder is to build muscle, the goal of the weightlifter is to get stronger and faster. The typical weightlifter's physique is much smaller than a bodybuilder's physique. Their muscles are dense, compact, and extremely efficient. Appearances generally do not matter to a weightlifter, and there are great variations in the amount of body fat each athlete carries on his or her body. Examples of weightlifters include Holley Mangold, Kendrick Farris and Lu Xiaojun.  
 
Weightlifters aspire to be able to lift weight as fast and as efficiently as possible. They train explosively, with a focus on heavy compound movements with few reps. The reason why they train this way is because weightlifters are primarily concerned with myofibrillar hypertrophy. Whereas sarcoplasmic hypertrophy results in larger muscle fibers for bodybuilders, myofibrillar hypertrophy results in more efficient muscle fibers for weightlifters. You do not use all of your muscle fibers when you flex your muscles. Some fibers contract with less force than others. Weightlifters train with heavy low rep compound exercises because those kinds of explosive movements teach the body's central nervous system to activate more muscle fibers and cause them to contract more forcefully. To illustrate, inducing myofibrillar hypertrophy is like putting a larger engine in a car. The size of the car does not change, but it moves faster because it has a more power under the hood. Reply
