One way I have found that keeps me working out every morning is to have a variety of workouts and routines. I will get attached to one workout and look forward to it every day, but eventually will start to feel a little bored with it. Once that starts, I immediately search for and find other workout videos, either from buying them on Half.com or Amazon.com, or by searching for them on YouTube.
Since the free workout routines on YouTube allow for more variety at no cost, I gravitate toward these first. Plus, most of the purchased workout DVD’s have sample routines on YouTube, so I can try them out before spending money on a DVD without knowing whether I will even like the workout.
