What is Tabata?

Tabata is a 4-minute high-intensity protocol: 20 seconds of maximal effort, 10 seconds of rest, eight rounds. It was studied by Dr. Izumi Tabata in 1996 and has since become the default "short but brutal" conditioning format. Our default adds a 10-second Get ready phase so the first round doesn't ambush you.
