I am far from having game. I've always just been straight forward when I actually tried for a girl. My game has always been having a job, being respectful and being honest.
My biggest accomplishment has probably been being a black girls first white dude. I was just like "I like how you look. How can I get more of your attention? Dinner? Drinks?" Got the "I don't date white dudes". I was just like "well give it a try". I'd hit on 20 black girls.
Be in proximity to them and having dedication and motivation on their level. Also don't lack confidence. I have a porcupine style confidence. Even if I don't win someone won't fuck with me twice. Dude may be huge but folding his knee back and taking him out the gym won't be worth kicking your ass.
Get custom shirts that say "Ur muscles R sexy" with a female in the background and wear them at the gym and go to shows. I have no clue but I'm sure muscular women have the idea "normal" dudes don't like them do they look at bigger guys.
Put yourself in their area, look them in the eye and "she" will see you.
