You do not need an expensive watch to start walking more. Begin with a short walk you can repeat, then gradually build your time and pace. Research links higher daily step counts with lower mortality, while trials suggest walking after meals can help manage the post-meal glucose rise. These findings support a useful everyday habit; they do not promise to reverse ageing.
At a glance: walking, effort and daily habits
- Zone 2 = easy-to-moderate effort; you can speak in full sentences, but you are breathing more deeply.
- No watch? Use the talk test.
- Steps: benefits level off around 6,000–8,000/day after 60 and 8,000–10,000/day for younger adults.
- A short walk after meals lowers the blood sugar spike.
- Build toward 150–300 minutes of moderate aerobic activity per week; start with what you can manage.
What is Zone 2?
Exercise physiologists divide effort into “zones”, usually based on heart rate. Different systems use three, five or more zones, so there is no single universal definition. In the popular five-zone model, Zone 2 is low-to-moderate intensity: hard enough to raise your breathing and heart rate, easy enough to sustain for a long time.
At this intensity your muscles rely heavily on fat for fuel and your heart, blood vessels and mitochondria adapt to deliver and use oxygen more efficiently. It is also gentle on joints and easy to recover from, which makes it ideal to do often.
The talk test: a practical guide to effort
| Effort | What talking feels like | Roughly |
|---|---|---|
| Very easy | You could sing | Zone 1 |
| Zone 2 | Full sentences, but you notice your breathing | Brisk walk, easy cycling |
| Moderate–hard | Only short phrases | Zone 3–4 |
| Very hard | A few words at most | Zone 5 |
If you use a heart-rate monitor, Zone 2 often falls somewhere around 60–70% of your maximum heart rate. Estimates of maximum heart rate based on age are rough, though, so the talk test is just as useful for most people.
How many steps make sense?
A 2022 meta-analysis of 15 cohorts found that more daily steps were associated with lower mortality. The association levelled off around 6,000–8,000 steps in adults aged 60 and older and 8,000–10,000 in younger adults. These are population findings, not a required minimum or a personal ceiling. Observational studies cannot establish that adding steps alone caused the difference.
In that analysis, results for stepping rate were less consistent after accounting for total steps. Start by adding manageable movement to your own baseline rather than chasing a universal step target.
Walking after meals and blood sugar
After you eat, blood sugar rises. Working muscles take up glucose without needing as much insulin, so moving soon after a meal blunts the spike. In a study of people with type 2 diabetes, a 10-minute walk after each main meal lowered post-meal blood sugar more than a single 30-minute walk at another time of day. Pooled analyses suggest that even 2–5 minutes of light walking after eating helps.
This is one of the easiest habits to adopt: a short walk after lunch or dinner, or simply walking around while on a phone call.
How to fit it into a working day
- Walk after lunch for 10–15 minutes instead of scrolling at your desk.
- Walking meetings or phone calls on the move.
- Get off public transport one stop early or park further away.
- Stairs, not the lift – a short burst that also builds strength.
- Evening walk after dinner, ideally with someone: social time and blood sugar control in one.
- Weekend longer walk or hike of 45–90 minutes in nature.
A simple weekly target
WHO recommends 150–300 minutes of moderate aerobic activity per week, or an equivalent amount of vigorous activity, plus muscle-strengthening activity on at least two days. This is general activity guidance, not a prescription for a particular heart-rate zone. Thirty minutes of moderate activity on five days reaches the lower end. Short bouts count too; an easy stroll may be light activity rather than moderate. Build up gradually and combine walking with strength training (see Strength Training After 40).
Check with your doctor before increasing activity if you have chest pain, unexplained breathlessness, dizziness on exertion, heart disease or diabetes with complications. If you take blood sugar-lowering medication, ask how walking after meals might affect your levels.
What to do tomorrow
Take a 10-minute walk straight after lunch or dinner, at a pace where you can talk but not sing. Repeat it for a week and see how your energy changes in the afternoon.

Frequently asked questions
What heart rate is Zone 2?
Often around 60–70% of your maximum heart rate, but age-based estimates are rough. The talk test – full sentences, but you notice your breathing – works just as well.
Is walking Zone 2?
Brisk walking often is, especially uphill or for less fit people. If you can sing, speed up; if you can only say a few words, slow down.
How long should a walk after meals be?
Even 2–10 minutes of light walking after eating can reduce the blood sugar spike; 10–15 minutes is a good habit.
