That's called congestion, that is, when the total blood supply increases, the capillaries of the target muscle are squeezed by the muscle, resulting in a decrease in throughput and congestion that cannot be discharged. When the exercise is in good condition, this pumping condition will be obvious, but it will fade after a short rest. Although training destroys muscle growth, short-term pumping is carried out slowly in the next few decades, but it has not actually increased.

General fitness and muscle training are based on years. For most non-professional players, those who have been trained effectively for less than 3 years and whose net weight is less than 15kg are novices. Since you are a novice, there is no perfect figure.
