Guy and I have made extensive flirty eye contact at the gym. I was feeling shy one day and immediately looked down when he tried to give me a sexy stare, and ever since he's been pretending to ignore me but I can tell he's been glancing at me a lot still.

What's the best way to show I'm definitely interested without being the one to approach first? Should I smile, walk by and say "hi"?

I say this because I hear from multiple sources that men prefer to do the chasing, and that they value what they have to work for more. But I think a lot of men are afraid of being seen as creepy in a gym. So I want to appear inviting but not aggressive.
