Gym girl encounter. Do you think I blew it?

A gal that caught my attention because she was wearing pink compression shorts looked me in the eyes and started on the machine next to me. I had seen her earlier but did not realize how pretty she was in the face. She did not have headphones on but beauty always makes me nervous. I finished and went on to the next machine without speaking to her. For the rest of the time she was there we kept searching for each other and stealing glances very obviously. As she left to leave she turned her head and stared right at me again. Im not really a social person because of my experiences in life but i do notice that women who do this actually get really frustrated will me after multiple encounters similiar.

Whats your opinion on how i should have handled this differently? If she is a regular i know i will have at least several more chances.

I may not see her again but there are many others especially since the New Years resolution stuff.
