Go the distance
Build stamina for the long haul.Endurance is built on time, not speed. Keep most sessions easy-to-moderate — a pace you could hold a conversation at — and make one session a little longer each week.
Your plan at a glance
3–4 days a week
Consistency is what grows stamina, not any single session.
Mostly easy-moderate
Conversational pace — you're teaching your body to keep going.
One longer session
Each week, one session that's a bit longer than the rest.
Grow it slowly
Add about 10% to your longest session each week — no more.
Worth knowing
The 10% rule: grow your longest session by roughly a tenth each week to build up injury-free.
How hard should it feel?
Your breath is the simplest intensity meter there is — no heart-rate strap required. Match the effort to the session: easy for warm-ups and recovery, moderate for most of your minutes, and short vigorous bursts when you want to boost fitness.
What a week looks like
Three or four sessions, one of them your 'long one' — extend it a little week by week.
Your sample session
The dose above stays the same whichever way you move. Pick your activity and grab a ready-made session to match.
The most accessible cardio there is. Walk briskly for moderate effort; add hills or short fast bursts to push harder. Kind on the joints and easy to keep up.
See the walking session →Efficient and easy to scale — jog gently for base fitness, or add fast intervals to spike it. Build up slowly and mix in walk breaks early on to stay injury-free.
See the running session →Low-impact and interval-friendly, indoors or out. Gentle on the knees, and hills or a turbo trainer make hard efforts easy to dial in exactly.
See the cycling session →Can't do it all? Do a little.
Even short bouts count — three brisk 10-minute walks add up to the same as one 30-minute session. The biggest step is simply starting; build from there.
