listen bro if you are serious about wanting to get as big as you say you have one option, EAT! honestly if i were you i would work on putting a meal plan together first and for most. trust me as an active athlete you are going to need calories that much more to grow! i would be sure and get at least four meals a day, and i would still throw in a good quality weight gainer in between meals. don't worry about adding fat right now, with you workouts you will be fine, unless you eat shit food but that's a whole other post!

you are gona need the calories and as said above pick a goal, if you wana get big go at it 110% or you will not grow. trust me man i know how you feel when i was younger and fighting i wanted to get bigger so bad and just couldn't seem to do so. i trained right and took every supplement under the sun back then but nothing! finally i stopped worrying about "dieting" and started eating like i wanted to be big, and it worked! as for training just do you football routine but try to stay with heavy weight/ low reps, adding a pm workout will most likely just be over training! i know you will most likely do what you want regardless bro but trust the good advise on this board, if you start Anabolic Androgenic Steroids (AAS) now you are going to waste a lot of future potential! besides going right back to square one, nothing is going to work if your diet is not in check for your goals, including aas! good luck bro and i hope this helps!
