Strength training is exercise that uses resistance to strengthen and condition the musculoskeletal system, improving endurance and muscle tone. Physiologically, the benefits of consistent strength training include an increase in muscle size and tone, increased muscular strength, and increases in bone, tendon and ligament strength. Lifting weights has also been shown to improve psychological health as well, by increasing confidence, self-esteem and self-worth.
Improved Performance & Physical Appearance
One important result of strength training is increased physical performance. Muscles utilize energy to produce movement, functioning as the engine or powerhouse of the body and strength training increases the muscles’ strength, size and endurance, which contribute to improvements in our work, sports and our general day-to-day activities.
Another benefit of a good strength-training program is its effect on our overall appearance and body composition, which can directly influence self-esteem and your confidence. Take, for example, a 160-pound man who has 20 percent body fat; 32 pounds of fat weight and 128 pounds of lean body weight (muscle, organs, bones, water, etc). By beginning an effective strength training program, he replaces five pounds of fat with five pounds of muscle. He still weighs 160 pounds, but he is now 17 percent fat with 27 pounds of fat weight and 133 pounds of lean body weight. Although his body weight remains the same, his strength, muscle tone, and metabolism have improved, giving him a fit and more attractive appearance.
