I am an eighteen year old guy, athletic build, but on the skinny side...I usually lift during the summers, and have to ease off whenever school starts due to sports and lack of time. However, even when i did lift, i did not see many changes. I could tell i was getting stronger, and maybe a little bit bigger, but not much....I just didnt feel like i was doing the right exercises. So my question for your guys is what kind of workout routine would you all suggest for me in order to get bigger...how many days a week, reps, exercises, etc. I would really appreciate if someone took the time to fill me in, thanks.
