Excuses are easy, saying why you can't do something is much easier than actually trying to do it. Don't throw in the towel before you actually pick up the gloves (hella cliche) but it's true... stick to it even if you can only exercise for 10 minutes. At the end of the day, ask yourself if you were any less productive than usual, The answer will probably be no—and your favorite excuse will be gone. Test your limits and try yourself. Be the hero of your own story.
