Don't take this the wrong way. I think hula hooping is a fine activity that probably burns a decent amount of calories. However, I've never worked at a job where employees jumps through these kind of hoops. I will probably look. And then look away. Pretty much everyone I know will think hula hooping at work is weird. If people tend to stare at you when you hula hoop, do hand stands, or pick your nose you may just have to stop doing it. Most people do not do these things at work and are happy nonetheless.
