Strength training is a set of physical exercises for the development of skeletal muscle to gain more athletic strength, endurance or muscle volume. In these exercises, a force objected repeatedly to the force generated by the contraction of muscles. The activity of the training is the basis for the practice of bodybuilding and weightlifting, but it is also a physical training for many sports that require strong physical condition. The fresh weight is also part of many to improve fitness or methods of care methods.The basic principles of weight training are the same, it is practiced to increase muscle mass (bodybuilding) to increase physical strength, to reinforce other sports, or in the sole purpose of improving general health. The training aims to stimulate the growth of muscle and associated tissues.
The weight training is done either using machinery or performing specific exercises. The principle is based on the concept of movement: it is to work a muscle or group of muscles against resistance imposed by the weight of the body, a specific machine or free weights (dumbbells and bars), and in this precisely controlling his actions. Through this repetitive motion, muscle fibers will grow (hypertrophy) to compensate another effort similar future.The movement is chained a number of times - we're talking about rehearsals - to constitute a series. After the series ended, the bodybuilder takes a rest period of a few seconds to a few minutes, then starts a new series, sometimes by changing the load.Typically, an exercise consists of several series, and several exercises are practiced during the session, which begins with a warm up and ends with stretching the muscles worked. Experienced athletes generally avoid working too often the same muscle group in order to allow the tissue time to recover and prevent injury. They provide the content of their training accordingly, this program is called the "split".
The details of the training varies depending on the purpose, time of rest, load, number of repetitions, etc..Practitioners fitness fight against monotony by changing multiple parameters of their training: the movement, the number of repetitions, number of sets, the breaks between sets and exercises, expenses and the rate at which they change from one series to another, the speed of execution of movements, catch, working angles, postures, with a training partner ... The possibilities are endless, generating various muscular sensations, and continuously providing new stimuli to the muscle, which is a guarantee of fast and smooth development of morphology.To solicit muscles, practitioners can apply the different ways there are many techniques known intensification to work the muscles. These methods and techniques require the help of a partner to be carried out safely. The most popular are forced reps, negative repetitions and partial repetitions
