Tabata is a four-minute long workout session consisting of eight rounds in total. Each round is the same; 20 seconds of intense exercise followed by 10 seconds of rest. Usually, four sets of exercises are repeated twice during eight rounds and more often than not consist of things like on-the-spot sprinting, squats, lunges, push-ups and crunches.
Although Tabata training is probably the shortest cardio workout around, it is the most effective when it comes to burning fat and increasing strength and stability. One of its most attractive features is that it also boosts metabolism, meaning that even after the session you will still be burning calories and fat.
