According to a new study published in the British Journal of Sports Medicine, walking speed can matter just as much as how many steps you rack up in a day. Researchers found that people taking fewer steps at a brisker pace had a similar drop in early death risk as people who logged more steps at a slower pace. That means the number glowing on your smartwatch is not the only thing worth chasing, your rhythm counts too.
Where did the 10,000 step number even come from?
That number never came from a lab. Study coauthor Emmanuel Stamatakis, a professor at Monash University, traced it back to a 1960s Japanese pedometer marketing campaign, not any real clinical research. For decades people have treated 10,000 like a hard finish line, and for a lot of folks that number just feels out of reach. A grandmother nursing a bad knee, a father working double shifts, or anyone new to exercise can look at that figure and decide it is not worth starting at all.
What did researchers actually find about steps and cadence
The team pulled movement data from more than 100,000 middle aged adults in the UK Biobank, all wearing activity trackers for a full week between 2013 and 2015. They sorted daily steps into four groups, under 5,000, 5,000 to 7,500, 7,500 to 10,000, and above 10,000, then measured each person’s fastest sustained cadence during their most active half hour.
After following the group for roughly eight years, the pattern was clear. People walking fewer than 5,000 steps a day who hit a peak cadence of at least 80 steps per minute had a death risk comparable to people walking 5,000 to 7,500 steps at a slower pace. The lowest overall risk still belonged to the 7,500 to 10,000 step range regardless of speed, but for anyone under that mark, picking up the pace made a real difference.
Why this lines up with what TikTok has been saying
This is where it gets interesting. Fitness creators have spent the last two years building entire followings around exactly this idea. Japanese interval walking, which alternates three minutes of brisk walking with three minutes of slow recovery, blew up online long before this study confirmed the science behind it.
The 12-3-30 treadmill routine and the Hot Girl Walk movement carried the same underlying message, that intensity and intention can outwork raw distance. Millions of people were already walking faster on purpose without a peer reviewed paper telling them to. Now the research has caught up to the trend.
How to find your own pace without obsessing over numbers
Stamatakis said the easiest gauge is how your body feels rather than a strict number. At a brisk pace your breathing should pick up and you should feel warmer, but you should still be able to talk in short sentences. If you want an actual figure, count your steps for 15 seconds and multiply by four, with 100 steps per minute serving as a rough benchmark for moderate intensity.
Harvard biologist Daniel Lieberman, who was not part of the study, pointed out that exercise really comes down to three levers, how much you move, how hard you move, and how often you do it. All three matter, and consistency beats any single motivated week. Anyone managing joint pain, balance issues or heart risk should build up pace gradually and check with a doctor before pushing harder. The real takeaway is simple. If you are short on time, walk faster. If your body cannot handle faster, walk more. Either path gets you somewhere good.
