In reply to Chive Talkin\':
I used to but I just did things that didn't require any equipment and mostly used it as an excuse to focus on the more mundane injury prevention/core strength routines or as a way to force me to train in a different way than I would at home. Resistance bands are easy to take to work if you need to add resistance training for something. If it suits to do a full on work out then pretty much every muscle in the body can be worked without equipment if you're creative and it has the added benefit of not making you look like the kind of guy that comes to work with a dumbbell :p
If there's no way you can use a pull up bar then upside down shoulder presses target the same muscle groups, i.e. upside down against the wall facing out and using your hands to raise and lower your body. It's quite a good one to do anyway if you do a lot of chins or pull ups because it works the oposing muscles, most people just do pull ups/chins and don't train the pushing muscles then get injured somewhere down the line because they're imbalanced. You can do pull ups under a desk (holding the edge, legs out) as well with your feet raised up on a chair. Again slightly different but targetting the same muscle groups and variety is good. It's hard keeping your core straight while you do it.
