Strength training is exercise that uses resistance--for example, weights--to strengthen and condition the musculoskeletal system, improving muscle tone and endurance. "Strength-training" is used as a general term synonymous with other common terms: "weightlifting" and "resistance training." Physiologically, the benefits of consistent strength training include an increase in muscle size and tone, increased muscle strength, and increases in tendon, bone, and ligament strength. Strength-training has also been shown to improve psychological health as well, by increasing self-esteem, confidence and self-worth.
These improvements have a great influence on our physical performance, metabolic efficiency, physical appearance and risk of injury. I'll go into each of these in detail, outlining some very exciting benefits of a good strength-training program that most people overlook or don't realize.
