Getting A Workout Like A Mouse

If it’s good enough for a mouse it’s good enough for a human right. This is like the hamster wheel found in pet hamster cages, although they are not as easy for humans to run on in actual fact. this photo may be Photoshopped, especially when you take a closer look at the photo.
There is such a thing as a manual treadmill though. Like the hamster wheel, the manual treadmill isn’t powered by electricity. instead, momentum is built by the runner on the belt, and this momentum becomes the pace at which the user is running. The only way to change this is to speed up or slow down.
