Yeah, figure out what you are lifting at work, i.e. your 15 rm, your 10rm, etc. If during work you're lifting around your 15 rm, you can still SD and then start with your 10's. Obviously not as effective as a true SD, but what can you do, you have to work. My work load varies each day, from repetitive 50rm stuff all the way to 1 rm loads, but during work there is a lot of "cheating" to move the load, so it's not exactly the same as workout technique.
