i know they dnt go together but still wanna do it

Ye,

soccer - a lot of running/cardio

bulking/powerlifting - mass, intense heavy weight lifting

Two different things, you can't have both, you'll do one more than the other one so if you play more soccer you'll burn a lot of muscle, but if you keep powerlifting you won't be as fast anymore with all the weight. But ye, good luck.

Its not what you know, its what you can do that counts!

Current Status: Bulking

if u try to bulk up in the gym, you will loose it all when u play soccer and run ... u gotta pick one man.. its extremly hard to bulk up with that much cardio. if u try and do both ull just get really cut up and wont get size.. u might be able to do it if u take some hardcore stuff but nevertheless, its still hard good luck

i mean i'm not saying its immpossible just alot harder take bcaa's before soccer..

I was training intensely for 8 weeks during the summer for rugby which involved a lot more fitness and speed training  then weight lifting but i still managed to gain 9lbs. It involves a lot of hard work, as everyone said already, you cant have both but you can still bulk up to a certain extent!

if u hit a plateau try using dumbells for chest .. do dumbell presses and pec dec for 2 weeks and go back to yoru routine
