I'm 15 and 168lbs and around 5'10". I play football and weight train anywhere from 3-5 times a week, but i haven't been able gain any weight (which is kind of needed seeing as I'm a lineman) is there anything in particular you recommend?

I need a really killer bicep routine.

curls, lots of them

Nigga I'm already doing curls.
Current routine:
3x8 narrow-grip curls
3x8 hammer curls
3x8 reverse grip curls

Look little bitch, your ass needs to get your ugly ass on an incline bench and do alternate bicep curls with some mother fucking dumb bells. All the way down and all the way up. 12 reps 1 set. Lower that fucking weight then do the same shit as before then lower the weight and same shit. After that go back up in weight doing 8 fucking reps. After that shits done, do some sit down concentration curls. Hit that shit hard. 8 reps each arm, no more sets. Get your bitch tits up afterwards and grab yourself a fucking curl bar and curl the max you can 6 - 8 reps, however much you can do. If you need some fugly ass slob to help you raise that fucking bar because your arms are too weak, then you get that asshole in front of you. FIGHT THAT SHIT ON THE WAY DOWN! Drop that bar is like dropping the soap, Not that your ugly ass could get some dick anyways but do you want to try? NO!

P.s. Do warmup exercises for your rotary cup, exercises that won't work the delts. Don't want anything tearing.
