not a lot i think you would go a long way with a smile, suggestions of alternative glute excercises and then suggesting lunch at a new vegan place thats just opened (im just guessing here, i dont have the confidence to talk to these women)
youre right, its just a matter of talking to them. Theres a chick that comes to my gym, amazing leg, cute face, blonde, and wears these shorty little tight booty shorts and usually a a tight top which she ties a knot in the back (which i have no fucking idea why she does it, maybe to make the front stretch more? but then again she doesnt have huge tits). Anyways.. They key to these girls is the first time just make an opening, the next few times a nod and a hello and maybe a small talk, and the 4th or 5th time you ask her out. For me, this long game usually works better because you distinguish yourself from the typical gym douche going up to her and within the first conversation asking her out.
i'd seen guys hover around this girl, i was doing cardio one day and she was stretching in front of me where the mats were. I noticed she had the iphone 7 because i saw her headphones were connected to the bottom middle of the phone with a piece of adapter, so i used that as my opening, just asked how she liked the new phone and if the earpods or iEar or whatever the fuck the new heaphones that come with teh phone are any good or not.. the point was just to talk to her about something and anything, without mentioning her routine or whatever, and then i told her my name and she told me hers and thats it, the next few times we just exchanged a smile and a nod or wave, the 4th time (saw her on a monday) i asked about her weekend etc and if she has a long weekend coming up, and the 5th time which was a thursday i asked her out for friday night and she said yeah.
the more slutty they dress, the more attention they want, but its also a catch 22... they dress slutty because they want attention, but if you show them the attention they want youd be no different than the other 50 guys, so for you to stand out you need to show her attention, but about something so trivial that you actually stand out
