m. Initially she was super interested telling me about her workouts and shit, working out near me and all that. As I showed a bit of interest, it seems like she has lost all interest.

Women flirt while they work out if they are attracted or not. It's them playing for time.

Secondly: are you sure she was interested in YOU,, rather than excited about talking about HER?

Now, I didn't do anything beta like talking too much or showing overt interest

So you listen to her gabbing on and express no interest? That sounds pretty beta.

g also I look like a gangsta,

If you look like a gangsta but don't act like it, you will attracted girls who like the gangsta thing then they'll find out you're not that and bail. You need to be more congruent.

Is gangsta her type?

Also, "don't talk much" doesn't mean negesarily I don't blab. In my experience it comes from not having anything effective to say.

Either physical(like a lot of gangstas), or verbal, you do need to hook her. She won't pick you up, she won't seduce you, plan logistics and ride you hard until you fall asleep and just have you wait for it. (and if she does, she probably stole your stash or a kidney)

shit test; pull back and let her come to you. it’s like fishing
