Ok so here is the thing. I meet a lot of girls in the gym where I work as a trainer.

Opening, attracting*, number closing*, kino I have down.

I have put stars next to attracting and number closing for a reason. As far as attraction goes, I feel as though I'm constantly getting IOI's but somehow I cannot get rid of the seed of doubt in my mind no matter what I do. How can I be absolutely sure?

Number closing. I can and do get numbers all the time. However, what if she has a reason to give me her number. i.e. if it is given in a professional/friendly sense. I think this is unimportant imo, but I put it anyway so you get the whole picture.

Kino, I add kino all the time. I even get it back quite regularly.

So the next step would be escalation. How do I escalate and move the endless amounts of opportunities I get further and in the direction that I want? Can it be done in this environment? A technical problem I feel in this situation is that you often see the girls regularly. A couple times a week or sometimes more. How do you approach this if you see them a lot? I get the feeling that you sort of have to start over from scratch and build up attraction again.

Just the fact that you're looking for certain goes against you. It shouldn't matter whether she is attracted or not. You need to get it in your head that no matter what you do, no girl will be 100% attracted to you. Their emotions change like grass in wind and she could lose attraction for you any moment. The best way to prevent this is to just take action immediately. Remember, you DON'T need to be sure.

You should aim to make your intent clear when you get their number. I just generally ask them for their number SPECIFICALLY to "hang out".

Typical conversation would be:

Me: *banter*
Girl: *banter*
M: You're cool, let's hang out later. What's your number? We're hanging out later.
G: Numberssss
M: Alright what's my name?
G: Johnny!
M: When are we hanging out?
G: Later!
M: Text you later.

I'm not sure what your last paragraph is asking. I don't think the gym should provide any problems for you but moving to another location isn't a problem either. If you're concerned that you lose attraction and have to re-build every time you see them then you should focus on closing more quickly as to avoid losing attraction.
