I have found that I am more successful at working out if I go to work out before I go to work. There is a gym at my office and it has pretty much everything I need. But the best part about it is that I'm not a morning person so I don't have to be dressed up to go to the gym.
I can just bum out for the work out. And it wakes me up and I can get ready afterwords and feel refreshed at work.
