What is Tabata?
Tabata training is a high-intensity interval training (HIIT) protocol created by Dr. Izumi Tabata. It consists of 8 rounds of ultra-intense work sprints (20 seconds) followed by brief recovery rest periods (10 seconds), for a total of 4 minutes. Ideal for burning fat, improving stamina, and full-body cardio workouts.
