10. Stability ball work
Not just for bouncing around on. Stability balls have a dozen names, but they are one of the best (and cheap) exercise tools around.
Simple moves like push-ups, sit-ups, and planks get way more challenging when trying to maintain stability on a rolling ball, which increases the effort of muscles greatly. In other words, less time needed to workout but better results.
Exercise is vital, no matter when you do it. By getting up and working out, you not only wake up, you stimulate your metabolism and put yourself in a better mood. All before your shot of caffeine. So night owls, are you ready to catch yourselves an early morning worm?
