My exercise program fell by the wayside when I started working full time.  I do a good amount of walking during the day so that helps a little bit to balance out the times I’m sitting or standing.  I try to go for a 20-30 minute walk several times a week, but I’ve only walked once this week so far.  I’m not trying to build up big muscles so I don’t need creatine. I just want to do light aerobic exercise for the health benefits.
