Ten squats every hour might do more for your body than that 30-minute walk you’ve been banking on. That’s the kind of claim that sounds too convenient to be true — but a 2024 study gives it real scientific footing, and neurophysiologist Louisa Nicola has helped bring the finding to a much wider audience.
The reason it’s resonating is simple: most people spend the majority of their waking hours sitting. Desks, screens, commutes, couches — modern life has quietly engineered movement almost entirely out of the day. And the health consequences of that are becoming harder to ignore.
Nicola, who has spoken publicly about the neurological and metabolic risks of prolonged sitting, has highlighted research suggesting that small, frequent bursts of movement may be more effective than a single longer workout when you’re otherwise sedentary all day. The science behind that claim is real — though the viral version of it deserves a closer look.
What the Study Actually Found
The research that best supports Nicola’s message involved 18 overweight or obese young men who went through four different conditions across an 8.5-hour sitting day. This was a controlled trial, not a survey or observational study, which gives the findings more weight.
The four conditions tested were:
- Uninterrupted sitting for the full 8.5 hours
- A single 30-minute brisk walk, with the rest of the day spent sitting
- 3-minute walking breaks every 45 minutes throughout the day
- 10 bodyweight squats every 45 minutes throughout the day
The primary outcome being measured was post-meal blood glucose — a key marker of metabolic health. Both the frequent walking breaks and the squat intervals outperformed the single 30-minute walk for blood sugar control during a sedentary day. That’s the core finding.
One important nuance: the study used bodyweight squats every 45 minutes, not jump squats every hour as the viral version of the claim sometimes states. That’s a meaningful distinction — bodyweight squats are accessible to almost everyone, while jump squats carry more impact and are harder for people with joint issues. The interval was also 45 minutes, not 60. The principle holds, but the specifics matter.
Why Frequent Movement Beats One Long Session on a Sedentary Day
The logic behind these findings connects to how the body handles glucose after meals. When you sit for hours without moving, your muscles become largely inactive. Muscle contractions — even small ones — help draw glucose out of the bloodstream and into working tissue. A single 30-minute walk can’t fully compensate for eight-plus hours of inactivity if the remaining seven hours are spent completely still.
Frequent movement breaks, by contrast, keep that metabolic process ticking throughout the day. Every time you stand up and do a set of squats, your leg muscles — some of the largest in the body — activate and pull glucose from circulation. Do that 10 or 11 times across a workday and the cumulative effect adds up in ways a single walk simply can’t replicate.
This doesn’t mean walking is useless. It means that how you distribute movement across the day matters, not just whether you hit a total step count or workout duration.
The Four Conditions Compared
| Condition | Protocol | Blood Sugar Control |
|---|---|---|
| Uninterrupted sitting | 8.5 hours of continuous sitting | Worst outcome |
| Single 30-minute walk | One walk, rest of day seated | Moderate improvement |
| Frequent walking breaks | 3-minute walks every 45 minutes | Strong improvement |
| Bodyweight squat breaks | 10 squats every 45 minutes | Strong improvement |
Both the walking breaks and the squat intervals performed better than the single 30-minute walk, according to the 2024 trial findings.
Who This Matters Most For — And Why
If you work a desk job, this research speaks directly to your daily reality. The average office worker can easily spend six to nine hours seated, and a morning or lunchtime gym session — while genuinely valuable — doesn’t neutralize the metabolic impact of sitting still for the rest of the day.
The squat-break approach is also notable for its practicality. Ten squats take roughly 30 to 45 seconds. You don’t need equipment, a change of clothes, or even much space. It’s the kind of intervention that can realistically be built into a workday without disrupting it.
For people managing blood sugar, weight, or cardiovascular risk, the implications are particularly relevant. Keeping post-meal glucose stable throughout the day — rather than letting it spike during long sedentary stretches — is a meaningful health outcome, not just a minor metric.
What Nicola’s Message Gets Right — and Where the Viral Version Slips
Louisa Nicola has played a real role in bringing this kind of research to public attention, and the core message is scientifically grounded. Frequent movement breaks genuinely can outperform a single longer workout when the alternative is hours of uninterrupted sitting.
Where the viral framing oversteps is in the specifics. The study tested bodyweight squats, not jump squats. The interval was every 45 minutes, not every hour. And the measured benefit was blood glucose control, not broader Alzheimer’s or neurological outcomes, which require different and longer-term evidence.
That’s not a reason to dismiss the finding. It’s a reason to understand it accurately — because the accurate version is already compelling enough to change how you think about your day.
Frequently Asked Questions
What exactly did the 2024 study measure?
The study tracked post-meal blood glucose levels across four different movement conditions during an 8.5-hour sitting day in 18 overweight or obese young men.
Did the study use jump squats or bodyweight squats?
The study used bodyweight squats — 10 repetitions every 45 minutes — not jump squats every hour, as some viral versions of the claim suggest.
Did squat breaks actually outperform a 30-minute walk?
According to the study’s findings, both frequent squat breaks and frequent walking breaks outperformed a single 30-minute walk for blood sugar control during a sedentary day.
Does this mean daily walks are no longer worth doing?
No. The study compared these approaches specifically within the context of an otherwise sedentary day — regular walking remains valuable for overall health.
Who is Louisa Nicola?
Louisa Nicola is a neurophysiologist who has spoken publicly about the health risks of prolonged sitting and has helped bring this area of research to wider public attention.
Can this approach help with conditions beyond blood sugar?
The study specifically tracked post-meal glucose, not neurological or other long-term outcomes — broader claims about Alzheimer’s or brain health require separate evidence and have not been confirmed by this particular trial.
