Tabata structure for multiple exercises — finish each one before moving on.
2 exercises × 3 rounds, 0:20 work / 0:10 break. The timer flows automatically from start to finish.
The original four-minute protocol. Eight rounds of 0:20 hard, 0:10 rest on a single movement.
Two movements stacked back-to-back. Eight rounds of each, with a one-minute reset between blocks.
Full-body sweat. Four movements, eight rounds each, one-minute reset between blocks. Brutal but balanced.
Fixed work/rest intervals, repeated for a set number of rounds.
Rotate through named exercises with optional breaks. Stations of any duration.
Simple timed rounds with breaks. Boxing, MMA, sparring.
Build any interval sequence from scratch, one by one.
