Walking for Your Heart: How Much Is Enough?

If walking came in a bottle, every doctor would prescribe it. It needs no equipment, no membership and no special skill, and it's one of the most studied habits in heart health. The questions men ask are practical: how much, how fast, and does a stroll to the mailbox count?

What the guidelines recommend

The Physical Activity Guidelines for Americans recommend at least 150 minutes a week of moderate-intensity activity, such as brisk walking, for adults. That's about 30 minutes, five days a week. It can be split into shorter bouts: three 10-minute walks count the same as one 30-minute walk. Add muscle-strengthening work at least two days a week (see The 4 Strength Moves Worth Doing After 50) and, for older adults, some balance training.

What "brisk" means

Moderate intensity is a pace where your breathing picks up and you feel warm, but you could still hold a conversation. A simple check is the talk test: if you can talk but couldn't comfortably sing, you're in the right zone. If you can't get a sentence out, ease off. If you could belt out a song, pick it up a little.

What about 10,000 steps?

The famous 10,000 figure started as a marketing slogan, not a research finding. Better evidence now exists. A 2022 analysis in The Lancet Public Health pooled data from 15 studies covering about 47,000 adults:

• More daily steps were linked with a lower risk of death over the study period, up to a point.
• For adults 60 and older, the benefit levelled off at around 6,000 to 8,000 steps a day.
• For younger adults, it levelled off at around 8,000 to 10,000.

These are associations from observational studies, and step counts are a rough measure. But the message is encouraging: you don't need marathon numbers, and moving from very few steps to a moderate amount brings the biggest change.

Why walking is good for the heart

Regular moderate activity is associated with lower blood pressure, better cholesterol and blood sugar levels, easier weight management and a lower risk of heart disease. It also helps sleep and mood, which matter more to the heart than people tend to think.

How to make your walks count

1. Find your baseline. Use your phone or a watch to see your average steps for a normal week, before changing anything.
2. Add, don't overhaul. Add about 1,000 steps a day, roughly 10 minutes, and hold it for a week or two before adding more.
3. Attach it to something. After breakfast, after lunch, the dog's evening walk. A habit linked to an existing routine sticks better.
4. Add some hills or intervals. Once a brisk pace feels easy, include a hill, or alternate two minutes faster with two minutes easier.
5. Look after your feet. Supportive, well-fitting shoes make a bigger difference than any gadget.
6. Take company. A partner, a friend or a walking group improves consistency, and conversation keeps you honest on the talk test.
