hey /fit/. noob here. i'm 5'11, 175 and athletic, used to run constantly, now i want to get in shape and gain a few pounds.

what you think of my routine? I've been going to this shitty gym (inb4 get a home gym or spend money $100 month on a nice gym). they don't have all of the necessities, but it's worked so far. of course, i have no fucking idea what i'm doing. i go every other day and basically do...

alternating sets of chin ups and dips
chin ups x10
dips x10
chin ups x8
dips x8
chin ups x6
dips x6

everything else is 3 sets of 8 reps. here's where i'm at:

-DB bench press (45 lb dumbbells).
-reverse barbell curls (50 lbs)
-DB rows (40 lbs)
-incline DB flys (30 lbs)
-alternating tricep pull down and bicep rope pull ups.
-21's (i can usually only get through like 1 and a half at 50 lbs).
-skullcrushers.

there are a few more, but you get the point. i'm just trying to build upper body (inb4 legs, I KNOW the importance). I've started eating 3000 cal. per day and I've gained about 5 lbs in a month). i mainly want to focus on my arms and chest and back

any criticism, whether constructive or not, is appreciated.
