How should I flirt with a hot cougar at the gym?

Ok this is out of the ordinary but there's this really hot blonde "older" women (looks late 20s-early 30s) at my local gym that I am attracted too. I am a 21 year old Indian and I've been complemented for being fairly good-looking and in shape by girls my age. Every time I hit the gym, I see this woman on the treadmill and lifting. It's as if we both run on he same gym schedule. Anyways, I've been giving her looks and she would give me looks back. Today while I was lifting dumbbells, she came up next to me to do some other exercises. I have a feeling she's feeling me. How can I escalade my interactions with this woman next time i'm in the gym without being creepy. Sounds like a fantasy but I'd like to make it a reality :)
