My legs feel weak but my body feels great. It shoots up my metabolism for the next two hours too, which is an added benefit to the stress release and exercise. In short, this little staircase is how I keep my ass from getting too wide while sitting in front of the computer at work.
You might not have stairs near you but I’m sure you have something. A desk you can jump onto, an empty conference room you can do push ups in, a roof you can do pull ups from. Whatever it is, do it once every two or three hours. Your stress level will go down and your body will thank you.
