I'm going to be home from school for 3 and a half month starting in the beginning of may. I'm looking to put on some weight and was wondering, if I got in a pretty good routine and worked out for 3 and a half months, how much bigger do you think I would get? Basically I'm looking for motivation. Just knowing that I could gain a certain amount of weight and physically look bigger would be really good motivation. But I'm looking for an honest answer. Also should I use those protein shakes? They are pretty expensive so unless they make a huge difference I'd rather save my money. But if they really do help then I'd deff buy them.
