The body-building apparatus is the main muscle training equipment of body-building enthusiasts, the existing body-building apparatus mostly realizes the resistance muscle stretching through the gravity traction of the balancing weight, and realizes the muscle exercise, and the body-building apparatus comprises a bending machine, a big flying bird, a small flying bird, a sitting type leg bending trainer, a horizontal type back leg bending trainer, a biceps trainer, a triceps trainer, a high pull-down trainer, a sitting type chest pushing trainer, a shoulder lifting machine, a butterfly machine, an abdominal muscle trainer and the like. The problems of the existing fitness equipment for realizing the resistance muscle stretching through the gravity traction of the balancing weight are as follows:
(1) the tension applied to the muscle needs to be adjusted by changing the pulling amount of the weight block, and the adjusted gravity is discrete gravity data (for example, 30 pounds, 40 pounds, 50 pounds, and 70 pounds) for manual adjustment, such adjustment cannot meet the fine adjustment requirement of the user, the muscle-building operation needs about 70% of the ultimate strength to perform the training operation, especially for a high-order muscle trainer, in order to achieve the best muscle-building training effect, the higher the ultimate resistance adjustment precision, the higher-order muscle trainer often needs to assist the trainer to manually apply a certain resistance on one side, because the adjustment width of the device is too large.
(2) The equipment is characterized in that: the resistance muscle stretching is realized through the gravity traction of the balancing weight, and the tension applied to the muscle is constant. In the training process of muscle fitness trainers, peak contraction is a very important training skill, and the peak contraction means that the active muscles are in the most tense contraction state when the muscles reach full contraction. If the weight is not locked when the muscle is fully contracted, the muscle can relax. To avoid this phenomenon, when the muscle contracts to the most tense position, a certain resistance reducing force is given to make the muscle in a completely tightened state, and the training class makes the muscle enlarged and the muscle line dividing line clear. The peak pinch operation is a relatively advanced training technique, and novice operation often requires a coach to guide the operation and prompt him to maintain the peak pinch state.
