The exercise with weights, initially was a discipline exclusive to the body builders back in the 60's's, which was a war of vanities, as all those attending gyms did everything possible to be stronger and bigger than the companion training. Later on became the basis of all sports, as the athletes began to see great benefits and improvements in its performance from their practice because they saw that got more endurance and strength and, above all, declining injuries in men as young women.
Now a days, weights, besides to be a tool of good appearance are used to stop the effects of aging, because with aging: the rapid contraction of muscle fibers or explosive muscle fibers (used for anaerobic exercises) stunt at a rate faster than our fiber contraction slow or fibers resistance (aerobic) and strength training with weights. Another of the benefits of weight training is to increase muscle strength, which brings three basic qualities: THE APPROACH which gives training based on the desired goal. RESISTANCE is the ability to working out in a moderate way on a long period of time such as a marathon race.

The consequences of becoming stronger with a weight training, are both physiological and neurological strength, the physiological changes are the muscle hypertrophy (increase in muscle mass), and the neurological changes which in most the cases occurs before the muscle are the coordination of movements.
Among the benefits of muscle hypertrophy, which is metabolically active tissue also increases, getting results in our metabolic rate and thus burning more calories, especially after exercise. This does not mean that simply because we train with weights we are going to lose weight. We recommend to keep switching with an aerobic activity and a balanced diet.
