High Intensity Interval training ( HIIT ) is a form of interval training that alternates short periods of intense anaerobic exercise with less intense rest periods.

Exercise studies have shown that High Intensity Interval training improve athletic capacity and conditioning along with improved glucose metabolism and fat burning.

Tabata is a form of High-Intensity Interval Training (HIIT) that is based on a 1996 study carried out by Professor Izumi Tabata involving Olympic Speedskaters.

Tabata training consists of 20 seconds of intense exercise followed by 10 seconds of rest repeated continuously for 4 minutes (8 cycles)

Tabata training can consist of one exercise repeated for all 8 cycles or alternatively 2, 4 or 8 different exercises performed throughout the circuit.
