The least you can do for the longest life.
You don’t need a coach, a power meter, or two-a-days. The longevity math rewards a boring, repeatable week: a base of easy hours and one genuinely hard day.
Why fitness is worth the hours.
In a Cleveland Clinic study of 122,007 patients, aerobic fitness was inversely associated with all-cause mortality with no upper limit — and being unfit carried a risk comparable to, sometimes greater than, smoking, diabetes, or heart disease.
The baseline is well established: the WHO recommends 150–300 minutes of moderate aerobic activity per week (or 75–150 vigorous), with additional benefit beyond it. The plan below clears that bar — and adds the high-intensity work that moves your VO2 max.
Four easy sessions. One hard one. That’s the plan.
This is the shape Peter Attia prescribes for longevity — about four Zone 2 bouts totaling 3–4 hours a week, plus dedicated high-intensity work — and it clears Huberman Lab’s 150–180 Zone 2 minutes each week.
The plan only works if the weeks keep happening.
Nothing above is complicated. The hard part is repetition — which is why Zone2 turns the whole plan into one weekly ring: minutes in zone, counted across every activity, with your watch keeping each session where it belongs. Close the ring, and the week did its job.
See your minutes in zone the moment you finish.
Zone2 makes it easy to track your minutes in each zone. There’s no readiness score to decode, no weird upsells, and definitely no fluff.
One ring. One week. Repeat.
Zone2 is free. Set your weekly Zone 2 goal once, and every workout you finish shows you exactly how much closer you are.
