A Tabata is a high-intensity workout protocol that has fitness and weight-loss benefits. It is also a very short workout. Is it like CrossFit? Is it like circuit training? It is a bit of both. Tabata training is attractive because it saves a lot of time for people. It offers the maximum benefit with the least amount of time used to get those results. Objective of the class is a 20/10 session repeated eight times. 20/10 means 20 seconds of all-out exercise followed by 10 seconds of rest.
