Tabata protocol

This is c&p from the All-round Strength Training blog...

The Tabata protocol consists of 20 seconds of maximum intensity exercise, followed by 10 seconds of rest. This cycle is repeated 8 times, for a total of 4 minutes. Tabatas can be performed using any exercise. The key is to perform at maximum intensity, which has the effect of increasing aerobic capacity and raising the body’s metabolic rate for long after the exercise itself has finished.

If you have never tried tabatas, you are in for a surprise! 20 seconds doesn’t sound like a very long time, but the body fatigues more quickly than you expect, especially if you are not used to high intensity work. Whatever exercise you choose, whether squats, press-ups, burpees or something else, count the number of reps you do in the first 20-second interval and try to get the same number of reps in each of the subsequent intervals. It’s a lot harder than you think.
