I had about 10 minutes to exercise before I had to pick up my two older daughters from school
yesterday. It was a busier day than usual for me with a couple of meetings besides my regular work.
Years ago, I would have put off my workout and would have left things for the next day. But since it
was a busy day as well, I knew that I may not have all that much time either. So, I picked up my kettle-bell (哑铃) and went to town for 4 minutes.
See, 4 minutes, if that's all you've got, is enough to give your body a great fat-burning exercise. How
did I get a killer workout in 4 minutes? I used a training workout discovered 10 years ago by a Japanese
Sports Scientist called a TABATA.
It includes 20-second periods of warm-up, followed by 10-second periods of rest and 4-minute
straight exercise. How is a 4-minute exercise able to burn fat? It all depends on the quality of work you do. Not on the quantity. Here's how I did it yesterday.
You should never forget your warm-up. A TABATA workout is 20 seconds of 2-arm Kettle-bell
swings, 10 seconds rest, 20 seconds push-ups, and 10 seconds rest. You should do those 4 rounds.
That's it. I was done in a total time of 8 minutes by the time and when I got to school my heart was still
pumping pretty hard.
A healthy body is needed for studying and working, and efficiency (效率) is the key to building a great body in the least amount (数量) of time possible and you can't get more efficient than a 4-minute workout.
