Strength Training is a form of training designed to build size, strength, and anaerobic endurance of skeletal muscles through the use of resistance. By utilizing weights, hydraulics, or the person's own body weight to provide increased resistance to muscular contraction, overloading specific groups of muscles.
Regular strength training provides a wide variety of benefits to the users, including greater muscular strength, improved muscle tone and appearance, enhanced bone density, increased endurance, and improved cardiovascular fitness. Most men can develop substantial muscles with regular strength training, and while women lack the testosterone to do so, both sexes use strength training as a way to improve their physical attractiveness. Women and men can develop a firm, "toned" physique, but an individual's genetic make-up will also affect how their body responds to weight training.
While muscle mass builds at different rates in different people, an increase in muscle mass through the use of strength training can help promote long term fat loss and helps dieters avoid the "yo-yo" effect of on and off dieting. Intense strength training workouts also help to elevate your metabolism for several hours, which can also help with fat loss. Stronger muscles also improve posture, provide better support for joints, and help reduce the risk of injury from everyday activities.
Strength training also helps promote good flexibility. With a strong, flexible body, you are less likely to be injured when playing sports as well as lifting or carrying objects. Overall, strength training contributes to the efficiency of the human body and its ability to perform. Elderly people who take up weight training have experienced an ability to slow the loss of muscle tissue associated with aging and even regain some functional strength, leaving them less frail. Weight bearing exercises can even help prevent osteoporosis as it helps increase bone density. Studies have shown that people who take up when training in their 80s and even 90s can experience a wide range of positive effects.
Does strength training just consist of using weights? Absolutely not. A wide range of strength training equipment is available that enables you to work different parts of the body and keep the exercises interesting. Keep in mind that when starting a strength training program, you are essentially starting a new lifestyle because an increase in strength is reversible. Like the old saying goes, "If you don't use it, you'll lose it!"
