You work up a sweat under your business clothes on monday, and it feels good. The entire first half of the week, athleticism is a major theme, either you're on the office softball team or there are a lot of hoops that need jumping through.

As if to compensate for all the excuses you've used to leave your desk and get moving recently, the end of the week burdens you with tasks that can only be completed in front of your computer screen.
