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
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.
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
