Coworker was checking me out at the gym—does this mean anything?

And while he was doing that two of the guys that he works saw him. Then the next day when I went into the gym the guy that was checking me out wasn’t in there but the two guys that he works with were and gave me small smiles. I was wondering if it means anything?
