Yes, you’re on the trailing edge of the bell-curve; it’s uncommon but certainly not unheard of or terribly unusual. In fact, it’s pretty understandable. This is often a transitionary period for people, trying to balance education with work and a social life – made all the harder if you’re one of the 60% of college students staring down the barrel of paying off those college loans. Some of you may have spent more time focusing on your studies or work. Others may still be in the middle of shaking off old identities and trying to work out social anxieties and inexperience.
Groups on the internet, such as the SS forums, have probably left untold amounts of guys disappointed with how they've looked after 3-12 months. Meanwhile, the "bro" who goes to the gym and does curls, bench, shoulders and a few chin-ups and leg presses totally blows the SS "student" out of the water, getting bigger arms, shoulders, pecs and upper back without that much weight gain. Thus trashing the SS mantra of people being unable to induce significant localised hypertrophy, which skinny fat guys benefit from aesthetically.
