Neither.
Neither...at least not since I really became hardcore into lifting heavy and developed my musculature to a degree that men ask me my back and ab routine. Don't get me wrong...I still look female...but I am always getting compliments on my back and arms.
My body isn't asian...or european..it's unique, noticeable and people now pay me to sculpt them!

I know someone earlier mentioned having an ass and how that wasn't really an asian trait...lol.
I had the "same body" 10 years ago without the strength training. I was cardio queen. Running all the time.
Butt flat.
10 years later...I run but mostly hills and sprinting, tons of squats, lunges..
I won a fitness competition where the winning factor was my butt!
I am now always asked how to get a butt like mine. Just last week a black woman asked me how she could get her butt like mine.
A black woman asking lil ol' half asian me about an aesthetically pleasing butt. Ponder that!
It's great that instead of people asking me, "What are you?"
they now ask me," WHAT DO YOU DO?

"
Can't say how many times I've been asked that on the gym and had one woman on the street just stop me and say, " I love your arms."
Of course I've had ignorant people say I am so slim because I am asian...bulls***.
That's not giving me any credit for putting in alot of work myself besides genetics. (My six pack tendency is actually shared by the females on my caucasian side)
I know lots of slim women who can't do pullups or pushups. SIze has nothing to do with it.
My filipina relatives might be slim...none have the six pack that me and some of my white cousins who workout do.
So neither asian or European..
I've been remade in the gym. You don't have to be bound by what genetics have given you or what society says you should look like.
go to the gym...do a one arm pullup and pushup in front of people and your race will be sooo insignificant when it comes to your body.
Trust me.
