How to Cram a Workout Into 4 Minutes

Nov. 3, 2013, 2013— -- intro: When it comes to fitness, there are few quick fixes. If you want a rockstar body, you're expected to put in hours at the gym for maximum results. Or at least 20 minutes a day, right? Wrong! Let me introduce you to Tabata training.

Tabata training is a type of high intensity interval training that supposedly can give you results similar to a 30- to 60-minute, moderate cardio routine in only 4 minutes. Whoa. I'm all about short, high intensity workouts, but 4 minutes!? Does it really work? It seems to!

In a 1996 study (there have been many), Professor Izumi Tabata looked at athletes who cycled for 60 minutes, 5 times a week, and those who did 7 to 8 sets of 20-second high intensity cycling followed by 10-second rest periods (about 4 minutes total), 5 times a week. Both improved their cardiovascular fitness, but he found the second group had an improvement in both anaerobic and aerobic fitness.

In other words, this type of workout seems to help your performance in high intensity, short duration activities, and also in longer endurance workouts.

Intrigued? Try it yourself with this 4-minute Tabata workout. (Although much of the research has been done on cycling and running, almost any high intensity exercise is thought to do the trick.)

Perform each of the following moves for 20 seconds followed by a 10 second break. Do the circuit twice. Remember to go hard! In order for it to work, you must be giving 100 percent for the whole 4 minutes.

Not sure if you've given it 100 percent? Make sure your heart rate is at 80 to 90 percent of your maximum heart rate while you are working out. To find your maximum heart rate, subtract your age from 220. Take this number and multiply it by 0.8 and 0.9 to find 80 to 90 percent of your maximum heart rate. Want to make it simpler? I always wear a heart rate monitor when I workout to ensure that I am working out intensely enough.
