Choosing signal at gym? Recommended approach?

Hey all, I’ve seen this same girl at the gym many times over this past week. I feel like she has glanced at me many times but I didn’t think much of it. However today I saw her twice actually learn forward out of her seat in the machine to catch a glimpse of me. I guess it was because I was moving to different spots around her, it seemed like she was wanting to keep track of me? Anyway I feel like leaning and looking at me is a good sign of interest. How would you recommend I approach?
