Muscle gain is a big process, and it seems unrealistic for a year or so. Because the body is made of meat. The absorption speed is limited. Muscle has a growth cycle, so it must be practiced every other day, otherwise the body can't stand it, but it is counterproductive.

Exercise depends on the mentality, not afraid of physical strength, but afraid of mental strength. As long as you exercise your muscles, your muscles can grow, depending on your quantity.

Your exercise method is the ultimate in time and equipment, just increase the amount.
