If you can really exercise good muscles and get the desired effect in this hobby of fitness, the time unit must be calculated in years, and it is by no means a few months to achieve the effect. Theoretically, bodybuilders activate or stimulate muscle and nerve tissue for a long time at the beginning of training. The result of continuous stimulation is that your strength is constantly improving, but the muscle dimension will not increase significantly at this stage. Generally, this period will last for several months to more than ten months, depending on personal physique and other characteristics. This is why fitness enthusiasts will make great progress in strength in the first 3 to 12 months, but the muscle dimension will not increase.
