20s work · 10s rest · 8 rounds
Tabata is a specific high-intensity protocol: 20 seconds of all-out work followed by 10 seconds of rest, repeated 8 times — just 4 minutes total. It's brutally effective and time-efficient.
This timer runs the exact 20/10 × 8 Tabata rhythm automatically, with a chime at every switch and a clear work/rest indicator.
Tip: Tabata only works if the work intervals are genuinely all-out. Pick one hard exercise (squats, burpees) and go maximum effort for all 20 seconds.
