Interested or just being nice?

I met here three mutual friends & she a pretty cool girl then I noticed one day as we started to acknowledge each other at the gym, that every time I would greet her with a fist pump her hand would shake not once but every time I would greet her. Another thing I’ve notice was she would walk around the gym with a strayed face, face down when she would workout but when she would see me she almost lights up with a big smile. She recently messaged me wishing me & my family happy holiday & it kinda shocked me a bit because she’s not supper active on social media & I haven’t seen her in the gym for a while now. So am i putting to much thought into this or is my gut feeling telling me something?
