1-Minute Workout

Could exercising just one minute a day be all you need to stay healthy?

Well, that's exactly what some researchers found. That 60 seconds of flat out, fast-as-you-can pedaling on the stationary bike was just as good as 45 minutes at a more moderate speed.

Now before you go hop on the bike, there are a couple of things you need to know. The workouts are actually 10 minutes long. You warm up for two minutes, then go all out, as hard as you possibly can for 20 seconds, then slow again for two minutes and super fast for 20 seconds. And recover by going slow for another two minute, sprint for the final 20 seconds, then cool down for three minutes, and you're done. You can run, bike, hop on the elliptical, or really any activity that gets your heart pumping. But you have to push yourself really hard during those 20 seconds.

Do this three times a week for 12 weeks, and you will improve your health and fitness levels. Now, there goes your last excuse for not working out.
