90 seconds in practice
Ninety seconds is 1.5 minutes — the default work interval in HIIT timers, a common plank or stretch hold, and the classic "elevator pitch" length. Timers display it as 1:30, and apps that sum intervals in seconds need 90 ÷ 60 = 1.5. Ten 90-second rounds with 30-second rests total exactly 20 minutes.
