I asked this women if she was using a machine and she just stared at me?

I was at the gym and this women standing right next to this machine. I already had my stuff there but did not used it yet. So out of courtesy I looked at her and asked very nicely are you using this? Her reaction was she just looked at me for a few seconds just staring and then went to doing a workout right next to the machine. She didn’t say anything at all. She was very attractive but I was not trying to make a move on her or anything like that. I was simply asking a question. Is this weird behavior by her?

She looked at me like one or times after that as well. I honestly did not do anything but workout.
