Could you elaborate on this? In the work environments I've been in, people go to the gym or outside to work out. I've never been in a work environment where it's acceptable to do your exercising in the office space. What are you talking about -- yoga, bicep curls, jogging, jumping jacks? I've worked at extremely liberal companies but that kind of stuff doesn't happen..
> and they need to feel comfortable to do that without being turned into sex objects
I don't think it's a person's right to hula hoop in an office and then be upset when they attract the attention of the rest of the office, regardless of sex on both sides. It's an unusual thing to do, so it will draw eyes.
