If you feel too much, you can reduce it appropriately, but if you feel tired, the last group should stop until you can't do any of them (this will increase), and increase the amount every once in a while. At least five to six days a week (preferably every day), you will obviously feel the increased muscles in about two months.
After all, I am only a freshman and young. There is no need to do what online professionals say. Those are more suitable for adults than for us. As long as I insist, it will have an effect. My big arms are obviously thicker than others.
I believe you will also become a muscular man! This is my own practical experience, and we are about the same age. If you don't understand, you can ask!
