Here's the Drill: 5 minute workout

Workouts don't have to be an hour long. They don't even have to be a half-hour long. Heck, sometimes they can even be as short as five minutes long!! The trade off in this case is increased intensity.

Whereas an hour-long workout could be spent doing a moderately paced walk on a treadmill, a five minute workout has to be an all-out assault on your body to achieve similar results. The next time you only have five minutes to squeeze in a workout, I'm sorry to say that you are all out of excuses.

Here's the Drill:

Perform 25 to 30 squat jumps. If you're a beginner to exercise, this may be too many. In that case, only do about 10 to 15. And, before I let people off easy, if 25 to 30 is a piece of cake for you, bump the number up to around 35 or 40. Do the exercise properly by squatting all the way down until your thighs are parallel to the floor, and then explode upward to the point where your feet leave the ground. Land with your knees slightly bent (to absorb the impact) and continue right into your next rep.

Oh no, you're not done. You still have about three and a half minutes left to go at this point. Take a thirty second break in between sets, but don't you dare sit down. Instead, walk in place or do jumping-jacks. Do anything that keeps you active, but does not require nearly the amount of effort as the squat jumps. Then, when thirty seconds is up, start your next set of squat jumps. Continue with this same routine (including taking 30 second breaks in between sets) until five minutes is up.

Believe me, by the time you're done, you'll be begging to get back to your hour long workout!!
