I am a 25 Indian male going to gym for past 2 months and still don't have biceps like this black girl ( https://youtu.be/dfWO7S0827o?t=253) [Embed] and she doesn't even lift. I mean wtf man, being mogged down by black men is one thing for us asian, but black women too? Honestly if I had a fight with this chick, she would rape my skinny fat body. Now I want to ask what makes them so muscly?

1. is it the genetics?
2. diet?
3. or they are involved very much in physical activities like lifting etc?
4. they take products which increase their test specifically?
