Why You Should Work Out on Work Days

In the wise words of Dolly Parton, "Working nine to five ... it's enough to drive you crazy if you let it." If you want to avoid the driving-you-crazy part and be more productive and less stressed, the answer is simple: Exercise.

University of Bristol researchers found that people who exercised on work days -- either before work or during lunch -- experienced less stress and were better able to handle the challenges of their workdays.

It's not surprising, really. Exercise can do wonders for your mood. And if you have a crabby co-worker, a demanding boss or unreasonable deadlines to deal with, you can certainly use a little boost in the mood department. And physical activity can increase your energy which, in turn, will make you a more productive employee. So get moving! You never know ... maybe your boss will notice your great performance and you'll get that raise you sorely deserve.
