Just recently hit my 6 week mark (roughly) since starting the gym just hoping for abit of advice and some tips

Made gains of roughly
10% on arms
2.5% chest
5% forearms
5% shoulders

Not sure if that's good or not, but i was really small to begin with (and still am)
Just wondering if that kinda percentage is good and probably with a diet lacking quite alot!

Also, noticed my Bodyfat, and waist/hip size has increased, as has my stomach!
i'm not sure if this is just water weight from creatine etc
Has anyone got any tips to help decrease my bodyfat etc whilst still bulking up??
