Hi, I also workout at work. I have a barbell, dumbbells, stability ball, mat, tv/dvd player, step, gym clothes, and lots of tapes at work. I workout every day in the lab and everyone knows that this is something I MUST do to remain sane. I could not work the long hours, 7 days per week without this distraction for 1-2 hours per day. I actually really enjoy working out in the lab and noone has ever given me any grief. I think I get less crabby when I exercise daily and my co-workers appreciate this. The only negative is I dont have a shower in the next room, but I have lots of changes of clothes, towels and a washcloth.
