Here is how it is done. Pretty much displays what you are talking about. There is a short ad before the video.

I’d say nothing. If she appreciates your compliment, you may have opened the door to more conversation, and then… then… trouble?
If she doesn’t appreciate the compliment, she’ll give you dirty looks forever.
I was swimming once in the lane next to a woman who I biked with on a Wed.nite ride. She and her husband were nice, and I enjoyed their company. Anyway, she got out of the pool, and guess what? Her suit was so old that I could see the crk of her a through it. I had just recently noticed that the suit that I wore was getting “see-through”, so I was in a helpful mood.
So, I went up to her and told her that I could see through the back of her suit and she might want to get a new one.
She said, “Uh… thanks…”, and things were a bit wierd after that. I’m sure I creeped her out.
Since then I’ve seen plenty of women whose tri suits while on their bikes or swimming suits are getting see-through. I don’t say a word. I suppose I might tell my sister or wife if theirs wear out, but that’s where it will end.
“Your chest is getting huge my man”
Do me a favor and say this to a chick sometime. Include the “my man”. I just wanna know what happens 
that is hilarious!
Why not just start by introducing yourself and make small conversation? You can tell if she is open to talking by her body language and her response.
It’s when the ~50+'s get up in my grill that I have a problem.
ouch! that hurts! 
Try again with this. Different results, guaranteed.
Finally someone else that truly understands the mindset of women.
For the past several months, I’ve seen this woman at the gym at least 3 days a week. We’ve ended up beside each other on the treadmill numerous times and I’ve also seen her doing time on the eliptical, rower, and free weights. I’m definitely not stalking her, I guess she just happens to workout at lunch everyday, so I see here almost everyday.
Anyway, I can really tell a difference in her physique since the beginning of the year, and today, instead of her usual loose tshirt and shorts, she had on this incredibly flattering (smoking hot) gym outfit that made my eyes pop out of my head. I know she’s been working hard at it, so I’d like to compliment her, but I’d like to do it in a non-threatening, non-creepy way.
Just for the record, I’m married, she’s married, and we’ve never had a conversation other than “hi” or “thanks” if one of us holds the door for the other one. So I don’t want to hit on her, just compliment her b/c like I said, I’ve seen how hard she’s been working, and Lord knows any compliments I’ve ever gotten have really motivated me to keep working hard. Any suggestions?
Here, I fixed it for you. 
For the past several months, I’ve seen this woman at the gym at least 3 days a week. I usually try to run next to her on the treadmill. I’m always watching her, but I don’t want to look that way. I knows that she works out at lunch everyday, so I make it a point to try and see her almost every day.

Just for the record, I’m married, she’s married, and we’ve never had a conversation other than “hi” or “thanks” but my imagination has been torturing me for months about what she must be like in bed. So I don’t want her to think I’m hitting on her, just compliment her b/c like I said, I really enjoy fantasizing about her, and Lord knows any compliments I’ve ever gotten have really motivated me to keep hard. Any suggestions?
These are all great!! Love it!
Quite honestly, I wouldn’t say anything other than usual friendly conversation. Women feel really exposed working out at the gym, and while some are clearly there for attention, most want to do their own thing, clear their head etc. Any comment about a woman’s body can so easily be misinterpreted, that I’d play it safe especially since are both married and thus not “interested” in eachother.
