Whoa, look at all the negativity in this thread, I can't believe what I'm seeing

. Alright, down to brass tax.
If they are girls you will see repeatedly then there is no need to rush things. The way I handle this is start a casual conversation in any way - asking to hop on the equipment is a good starter. Again, the focus shouldn't be on the opener but on what you do afterwards.
[Ace] Hey, how many sets have you got left
[HB] Three.
[Ace] Mind if I hop on inbetween your sets?
[HB] Yes/Sure/Whatever
[Ace - without changing her weights] Whoa... what does a small girl need that kind of strength for? You want to become a boxer?
[HB] Some response.
And I'll just leave it at that. I will see her again at some point, depending on how receptive she is I might ask her to flex, talk about '1 million dollar baby', nickname her 'boxer girl' or whatever. Just build a very basic and superficial connection, so that the next time I see her, she will already have talked to me. All I want to do at the gym is build some comfort (no, I don't want any MM maniacs telling me that I need to start with attraction).
[Ace] Hey, you again! How's things?
[HB] Pretty good... yourself?
[Ace] About 8 out of 10. It would have been 9 if a girl hadn't stolen my favorite workout t-shirt last night.
[HB] She stole your T-shirt?
[Ace] Come on, I bet you've done this before... You spend the night at a guy's place, then you wear his clothes when you go home in the morning.
[HB] Can't you get it back?
[Ace] Huh? Yeah, right. Come off it, don't act like you don't have some guy's t-shirt in your closet.
The above was invented by Tucker Max, and it's fucking genius. It's different, and you're already acting like you've known her for a while. Combined with the fact that you've already spoken to her a few times, it makes the next bit easier.
After I've done this a couple times, I might try to catch her outside as she is leaving.
[Ace] Hey, done pumping iron for the day?
[HB] Yeah, I'm just gonna head home and eat/go to sleep/whatever
[Ace - C&F] What an exciting life you do lead... which way you headed?
[HB] some direction
[Ace] Cool, I'm meeting a friend in 20 minutes at [some bar/coffee shop], I'll walk with you.
If I did that without talking to her previously, it would be weird - but that way there already is some comfort. It's a bit of a stretch, but they always agree.
You don't need to be super-high energy, just keep it cool and casual. Mystery's 'what do you think about when you work out' gives you nice leeway into other threads if you blank.
... or you could not open at all. Choice is yours. Just take it easy and get to know her a little before you bring out the big guns outside the gym. Worst-case scenario, you'll be exactly where you started, best case - you'll get a lay. It's not rocket science.
If you play it right, you might get other HBs notice you talk to other good-looking girls. It's never worked in my advantage yet, but I'm sure that over time....
