The Tabata Training workout requires 8 intervals of 20 seconds-all-out intensity exercise followed by 10 seconds of rest. Many of you might think how can one do 8 intervals in just 4 minutes? However, according to the research result by Professor Tabata, it is proven the best cardio workout as one can achieve both the aerobic and anaerobic exercises at the same time.
