Weight training

      Weight training is a structure of exercise for developing the strength and size of skeletal muscles. It is a common type of resistance training, which is one form of power training. Properly performed, weight training can provide significant functional benefits and improvement in overall health and well-being.

      In one common training method, the technique involves lifting increasingly increasing amounts of weight, and uses a variety of exercises and types of equipment to target specific muscle groups. Weight training is first and foremost an anaerobic activity, although some proponents have adapted it to provide the benefits of aerobic exercise.

      Weight training differs from bodybuilding, weightlifting, or power lifting, which are sports rather than forms of exercise. Weight training, however, is often part of their training regimen.

Benefits

       Many people take up weight training in the belief that it will get better their physical attractiveness. Some men can expand very substantial muscles; most women lack the testosterone to do this, but they can build up a firm, "toned" physique, and their increase in strength is balanced to that achieved by men. Ultimately an individual's genetics dictate the answer to weight training stimuli.

       The body's basal metabolic rate increases with increases in muscle mass, which promotes long-term fat defeat and helps dieters avoid yo-yo dieting. Moreover, strong workouts elevate the metabolism for several hours following the workout, which also promotes fat loss. (Weight-training alone will not reduce levels of body fat without the help of a suitable diet.)

      Weight training also provides purposeful benefits. Stronger muscles improve posture, provide better support for joints and reduce the risk of injury from daily activities. Older people who take up weight training can reverse the loss of muscle tissue that normally accompanies ageing, and by doing so become less frail. They may be able to shun some types of physical disability. Heavy, weight-bearing exercise also helps to prevent osteoporosis.

      The benefits of weight training for older people have been complete by studies of people who began engaging in it in their 80's and 90's.Stronger muscles improve appearance in a variety of sports. Sport-specific training routines are used by many competitors. These often specify that the speed of muscle reduction during weight training should be the same as that of the particular sport.

      One side-effect of strong exercise is that it increases levels of dopamine, serotonin and nor epinephrine, which can help to improve mood and counter feelings of depression (although in some cases this can front to an almost addiction-like desire to exercise).
