Seventy-five seconds is a minute and a quarter — a comfortable in-between length for a brewing or steeping step, a slightly longer breathing exercise, or a steady rest between efforts. It is the spot between a one-minute and a ninety-second countdown.
Four rounds of seventy-five seconds is five minutes; eight is ten. Tell the editor how many rounds to run whenever you need the same length more than once.
A 70 second timer — one minute and ten seconds, for when a flat minute is not quite enough. Repeats as many times as you set.
A 90 second timer — a common microwave time, 1.5 minutes for any task, and the classic rest between heavy sets. Repeats as needed.
