You've been following your workout routine for weeks when suddenly, you throw your back out (again). Unfortunately, injuries are just part of life. But just because you might not be able to work out for a few days doesn't mean you need to turn into a couch potato. Go for an easy walk, and then take the time you would have spent at the gym and use it to cook yourself a nutritious meal. A healthy lifestyle is made up of a bunch of little things, so don't give up when one area hits a roadblock.
