The 20/10 Tabata timer: 20 seconds of all-out work, 10 seconds of rest, repeated for eight rounds — four minutes total. The pattern comes from Dr. Izumi Tabata’s 1996 study, where athletes trained in exhaustive 20-second bouts at around 170% of VO2 max with 10-second rests between them.
This preset loads a single movement — burpees — but anything you can push hard for 20 seconds works: air squats, mountain climbers, kettlebell swings, or sprints on a bike. Press start and the timer runs the full sequence from first work interval to last. Want a different movement, more rounds, or a warmup? Open the preset in the editor and make it yours.
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.
