K, to start off I'm a naturally big dude. I'm 6'1, and 240 lbs at the moment. Im a little squishy atm, but nobody would call me fat if they saw me (im just tall, thick, and wide). For example, at 200 lbs, I look sickly and gaunt. Anyway, I used to train like a freak and 2 years ago I was a true beefcake. Since then I've lost strength and muscle mass. I wanna get back into it, but I'm only interested in training my upper body at this point (I don't wanna hear that my priorities are wrong and that I should be squatting/dead-lifting - I'm fully aware that those are the most effective lifts. I'd like to have healthy knees and back later in life. plus i have long legs and shorter arms, so those two lifts really take a toll on my body).
I guess I'm wondering what a good routine is at this point (I'm 26 right now). I have time for maybe 2-3 lifting sessions a week. Ideally I'd like to do all pull/chin-ups and dips, but my strength/body weight ratio is not that great right now. I just wanna regain lost muscle, so I should be able to do so without much hassle, especially since I'm meso-ecto.
