Interval exercises created by Dr. Tabata of the National Institute of Fitness and Sports in Tokyo. The assumption of the classes are very intense exercises performed for 20-30 seconds, followed by 5-10 seconds breaks. The series are repeated up to 8 times. The training is very demanding and, according to its assumptions, it is to bring the body to the limit of possibilities. Thanks to this, fat burning continues even after the training. Classes for intermediate and advanced people.
