Strength training is also recorded as far back as ancient Greek and ancient Persian times. Weightlifting is used as an end to achieve different goals. For example, in weight training, a type of exercise using weights to increase muscle strength, and in bodybuilding, a form of body modification for aesthetic reasons. Strength training, bodybuilding, and working out to achieve a general level of physical fitness have all historically been closely associated with weightlifting. Weightlifting is very beneficial for health in countless ways. Weightlifting induces the production of collagen proteins which helps build structure and strength of tendons and ligaments. It also is optimal for promoting and improving joint stability. Weightlifting can also increase metabolism and increases resting metabolic rate. This means the body can burn calories faster and the body uses those calories to increase and build muscle mass. However, it is possible to engage in a training regimen for any of these purpose using exercises or equipment other than weights. Conversely, because the goal of bodybuilding is often to generate a particular appearance, a person who engages in weightlifting only to increase strength, or for competitive purposes, may not achieve the physical appearance sought in bodybuilding. Weight training aims to build muscle by prompting two different types of hypertrophy: sarcoplasmic and myofibrillar. Sarcoplasmic hypertrophy leads to larger muscles and so is favored by bodybuilders more than myofibrillar hypertrophy, which builds athletic strength. Sarcoplasmic hypertrophy is triggered by increasing repetitions, whereas myofibrillar hypertrophy is triggered by lifting heavier weight. In either case, there is an increase in both size and strength of the muscles (compared to what happens if that same individual does not lift weights at all), however, the emphasis is different.

Notably, weightlifting purely to develop physical strength can lead to the development of a very different body type than weightlifting for bodybuilding, with powerlifters and Olympic weightlifters tending to have endo-mesomorphic bodies, and bodybuilders tending to be more mesomorphic. The two main methods of weight lifting to build strength and muscle mass are hypertrophy and overload. Training for muscle size is usually done by achieving hypertrophy which is training with a lighter weight at higher volume or more repetitions. Muscle size increases due to metabolic fibers that result in visible muscle mass growth. Training muscles to build strength is typically achieved by the overload method. Overload involves training with increasing weight at each set. It can also mean increasing volume of repetitions at the same weight for each set. Both overload methods are optimal for building muscle mass and strength, however, lifting heavy weights at a lower volume or less repetitions is very optimal for building strength.
