Tabata is a version of HIIT (High Intensity Interval Training) based on a 1996 study of Professor Izumi Tabata. Exercise is composed of 20 seconds of ultra-intense exercise followed by 10 seconds of rest, repeated continuously for 4 minutes (8 sets). According to his study, athletes that trained 4 times per week using this method obtained gains similar to a group of athletes that performed steady state-training 5 times per week. Moreover, the Tabata group had gained anaerobic capacity benefits.
A Tabata timer is needed to complete this exercise. Current Tabata timers are cumbersome and mostly offer poor user experience. Tabata Timer is an elegant audio-visual experience, combining simplicity with functionality.
