Start to train with a personal trainer according to best practices to achieve your dream effect! Do not have illusions! Going to the gym and lifting weights without a proper plan will not bring you results. Only the appropriate combination of repetition, series, weight, and muscle parts that are being exercised can lead to increased muscle mass.
Bodybuilding training involves regular muscle contraction. However, the weight must be appropriately selected so as to produce an effect while not injuring yourself. Regularity and cyclicity are extremely important in the process of building muscle mass. Another important principle is to constantly stimulate the muscles, avoiding the muscles getting used to any specific movements. There are many details of exercise techniques that determine the result. Get to know all of them by exercising with a personal trainer!
