A full minute of work against just twenty seconds of rest — a 3:1 ratio that takes the hardest thing about minute-long intervals, the sheer length, and pairs it with a recovery barely long enough to wipe your hands. Eight rounds run 10:40, and the back half is where the session is won or lost.
A minute is far too long to sprint, so settle into a strong, even output you can defend — then feel the twenty-second rest give back almost nothing before the next minute begins. It is the natural step up from the [60/30 timer](/hiit-timer/1-minute-work-30-second-rest): the same minute of work, a third less rest. Choose a movement you can hold a steady pace on — rower, bike, swings, step-ups — and add a warmup or trim the rounds in the editor while you build up to the full eight.
Equal work and recovery — the dependable 1:1 where the last round still matches the first. The cardio base you’ll actually come back to.
All-out efforts with a full walk to recover between them. One for the track, a hill, the bike, or the rower.
Work-heavy, recovery-light — sustained minute-long pushes for building an engine that holds up under fatigue.
The 2:1 workhorse of conditioning circuits and bootcamps: long efforts, short rest, fatigue stacking as you go.
Minimal-rest conditioning that puts the heart rate up early and keeps it there. Pace it to last, not to peak.
The bootcamp class clock — station-friendly rounds where the rest is just long enough to rotate.
An easy on-ramp to interval training: short work, real rest, every round at the same honest effort.
Tabata’s relentless cousin — barely-there rest and maximum sweat in well under ten minutes.
The hub’s toughest ratio: a near-minute of work against a single breath of rest. A grinder for the patient.
The hub’s most extreme ratio — five seconds is a reset, not a rest. A brutal six-minute finisher; pace it like a grind.
Four 4-minute near-max efforts with 3 minutes easy between, plus a warm-up and cool-down. The classic VO₂ max protocol for runners, cyclists, and rowers.
