Office bluessss

Does anyone have any suggestions on how to burn a few extra calories here & there while cooped up in an office all day?  I'm still in college, so I'm used to having to walk to class, walk to friends' houses, walk to the store, etc.,  but now as a summer employee I hate the idea of being stationary for 8 hours a day! 

I asked kinda the same question look down at desk workout there were a couple of posts down there

Here's the link to that thread for you

Do you get any breaks during the day? 30 min or an hour for lunch?  I walk!  Wether its 10 minutes or 45 at lunch time, I get up and walk! Outside, inside... it doesn't matter!  Climb a few flights of stairs, maybe.. (I wouldn't want to do anything too strenuous, don't want to be sweaty back at the desk). 

If you feel comfortable, ask around. I bet sombody else does something around the office just to get up for a little bit and break monotony.
