Should I date the woman who rejected me, now she's attracted to me cause I weightlift?

This woman I know and liked was never really attracted to me and would always avoid me when i talked to her and just never had much time for me, that is until i have been weightlifting. I caught her gazing at my bicep and then she quickly looked away. Since then she's been really nice and taking much more interest in me.
