Welcome to the boards brother!! Definately a good foundation to build on. Similiar to myself. Also looks like you dont gain muscle at a quick rate, though I could be wrong. Im the same way. Im not sure how dedicated or serious you are about gaining muscle. Some people do it casually, others live and breathe it. You sound more casual about lifting. Youll really have to make it a lifestyle if you want to gain solid mass and maintain it. So Id say "Fuck summer fun!!" haha. If youre going to take it easy for a few months during summer, at the very least Id reccomend you do some maintenance work. I know Ill lose alot if I train light for 2 months, or not at all. It can set you back a long way. Ive been training nearly then years without the AAS and still making gains. Its a harder and longer road, but Id like to build a larger foundation before going on it. And Id reccomend the same. Either way, good work and KEEP KILLING THAT SHIT!!
