Cardiovascular risk almost halved by a few minutes of intense exercise
- Past studies show that getting enough physical activity can help lower a person’s risk for major adverse cardiovascular events (MACE).
- Researchers from the University of Sydney have found that just 1.5 to 4 minute small bursts of high intensity exercise throughout the day may lower a person’s MACE risk.
- This correlation was observed more significantly in female participants compared to male participants.
“Physical inactivity is a major public health issue contributing to
“There is a pressing need to identify feasible ways and support people to be physically active. Structured exercise such as gyms, running, classes, etc is fantastic towards these goals but only 20% of the middle aged and older population do it regularly,” he pointed out.
Stamatakis is the lead and corresponding author of a new study recently published in the British Journal of Sports Medicine that has found that just 1.5 to 4 minute small bursts of high intensity exercise throughout the day — scientifically known as vigorous intermittent lifestyle physical activity (VILPA) — such taking the stairs instead of an elevator or carrying groceries a short distance may help lower a person’s risk of MACE, especially in women.
For this study, researchers analyzed UK Biobank data from more than 103,000 middle-aged men and women with an average age of 61. All participants had worn an activity tracker 24 hours a day for a full week between 2013 and 2015.
About 22,000 participants said they did not follow any structured exercise program or only took one recreational walk a week, while the remaining participants said they regularly exercised.
Researchers used the activity trackers to determine which participants had bouts of VILPA during the day and for how long.
“Incidental physical activity, things we do as part of our daily routines, offers many untapped opportunities, but we do not understand what is the best way to promote, and how to support people — VILPA offers such an option,” Stamatakis explained.
“These are short bursts of vigorous incidental activity, typically lasting [between] 10 seconds [and] 1 minute, that are part of people’s daily living. This kind of activity may be more feasible than structured exercise for many people as it does not require preparations, time commitment, or traveling to a facility to be active,” he detailed.
“Using advanced wearable measurement methods that allow us to scrutinize the effects of daily movement at a very high resolution — 10-second time windows — we wanted to understand what are the effects of VILPA on major cardiovascular disease events,” added Stamatakis. “No such study has been published before.”
Study participants’ cardiovascular health was tracked until November 2022.
Upon analysis, researchers found that female participants with no formal exercise regimen who recorded an average of 3.4 minutes of VILPA a day were 51% less likely to have a heart attack, 67% decreased risk for heart failure, and 45% less likely to develop any type of MACE compared to female participants who did not clock any VILPA during their day.
Additionally, scientists discovered for women that even VILPA amounts of 1.2 to 1.6 minutes a day were associated with a 40% decreased risk of heart failure, 33% lowered risk of heart attack, and 30% lower risk of all MACE.
“This finding is significant for at least two reasons,” Stamatakis said. “First, it represents a much lower amount of physical activity [than] any current exercise related recommendation, and this activity is incidental — which implies that it may be easier for many people to incorporate it into their daily routine.
“The second noteworthy aspect of these findings is that we should not be fooled into thinking that small amounts of VILPA are a quick fix of a complex problem, like physical inactivity,” he continued.
“The beneficial associations we observed were in women who committed to short bursts of VILPA almost daily, several times each day — nine to 10 bursts on average. Turning such behavior into habit is not necessarily easy. Our results show that even a little bit of higher intensity activity can help and might be just the thing to help people develop a regular physical activity, or even exercise, habit in the long term. In most occasions people who are unaccustomed to vigorous exertion will need support to develop such a habit.”

When looking at male participants, those who averaged 5.6 minutes of VILPA each day with no formal exercise had a 16% reduced risk of having any type of MACE than those who did not clock any VILPA. However, scientists did not find any correlation between VILPA and separate types of MACE.
“It is hard to speculate why we observed this, our study was not specifically designed to understand mechanisms,” Stamatakis said.
“However, there is a good possibility that because men’s relative VILPA intensity was only 70% versus 83% for women — around 20% higher — [meaning that] women exerted themselves more during VILPA bouts, and as a result we could see a markedly lower cardiovascular disease risk in women, in the long term.”
“We are now examining the associations of incidental physical activities of any intensity, light, moderate, as well as vigorous, and heart disease risk,” he added. “We are particularly interested in understanding what is the ‘heart health value’ of each minute of moderate and light intensity activities against each minute of vigorous (activity).”
After reviewing this study, Cheng-Han Chen, MD, a board-certified interventional cardiologist and medical director of the Structural Heart Program at MemorialCare Saddleback Medical Center in Laguna Hills, CA, told MNT that it is very promising to see such dramatic improvements in cardiovascular disease-related mortality with seemingly small amounts of vigorous exercise — something that could conceivably be accomplished by most people.
“Cardiovascular disease still remains the major cause of morbidity mortality in the world, so any intervention we can do to help lower that disease profile will have a great impact on the country’s health,” Chen continued.
“So we specifically promote lifestyle interventions that people can do on their own to improve people’s heart disease risk as preventive medicine, rather than waiting for the disease to progress and for us to have to intervene, either through medicines or through procedures,” he told us.
MNT also spoke with Rigved Tadwalkar, MD, a board-certified consultative cardiologist and medical director of the Cardiac Rehabilitation Center at Providence Saint John’s Health Center in Santa Monica, CA, about this study.
“My initial reaction to this study is one of optimism,” Tadwalkar commented. “The findings suggest that even minimal amounts of VILPA can significantly reduce the risk of MACE in women who typically do not engage in structured exercise. This is especially encouraging for patients who find it challenging to adhere to traditional exercise regimens due to time constraints, physical limitations, or other barriers.”
“The study highlights the potential of incorporating brief, intense physical activities into daily routines as an alternative to more conventional exercise programs, offering a practical and accessible strategy for improving cardiovascular health,” he continued. “The gender-specific results also underscore the importance of tailoring exercise recommendations to individual needs, which could lead to more personalized and effective prevention and treatment plans.”
For those looking to increase their daily VILPA, Chen said there are different types of activities people can incorporate throughout their day for brief periods of time.
“The easiest would be to use your environment to your advantage,” he detailed. “For instance, if there are stairs in your home or in your workplace, then we’re talking about just taking 1 to 2 minute brisk walks up and down the stairs just a few times a day would accomplish what the study has shown. This study also mentioned that just vigorous day-to-day, lifestyle activities such as carrying heavy groceries could also provide the same heart health benefit.”
Tadwalkar advised setting reminders to move every hour can prompt these brief but intense activities,
“Many smartwatches and wearable devices already provide this capability,” he continued. “For those working from home or in an office setting, consider using a standing desk and/or periodically performing quick exercises — some effective options include jumping jacks and squats.”
“The key is to find opportunities to increase the heart rate in short intervals throughout the day, making physical activity both manageable and effective,” Tadwalkar added. “These strategies not only help to reduce cardiovascular risk but can also improve overall energy and general well-being.”

The Case for Ditching Your Fitness Trackers

I have a love-hate relationship with the smartwatch on my wrist. This relationship is no doubt shaped by the fact that I write about fitness tech for a living, but I know I’m not alone in succumbing to an obsession with numbers from my wearables. Did I hit 10,000 steps? What’s my resting heart rate today? Is my sleep score better than yesterday’s? When did progressive overload turn into screen time overload, too?
The fitness tech boom is showing no signs of slowing down any time soon—and with it, we consume a constant stream of promises that this data will make us healthier, stronger, and faster. With the sheer amount of health insights potentially available to us at any time, it’s easy to get overwhelmed. I’ve watched my least health-anxious friends become consumed by metrics they’d never heard of two years ago. They’re tracking bone density trends, obsessing over cortisol levels, panicking about stress scores that fluctuate for reasons no algorithm can fully explain. I can feel my fitness trackers pull me away from genuine wellness and into a mental health disaster. The good news: When I look up from my screens and start talking to real people, I see I’m not alone in wanting to unplug and push back against the overly quantified self.
A growing anti-tech fitness movement
When I put out a call on Instagram asking people about their relationship with posting workout data and fitness content, I received hundreds of responses from people exhausted by the performance of fitness. Even if your only audience is your own reflection, simply owning a wearable can create a real barrier between feeling good about your body and your fitness journey. Did I work out enough today? Will my friends see that I skipped a workout? Should I push through injury to maintain my streak?
For these reasons, celebrity trainer Lauren Kleban says she doesn’t like to rely on wearables at all. “Counting steps or calories can quickly spiral into a bit of an obsession,” says Kleban, and that “takes the joy out of movement and away from learning what’s truly best for us.” She says her clients want to focus on their mind and body connection, now more than ever. There’s a real, growing desire to rebuild a sense of intuition that doesn’t depend on feedback from a watch.
Similarly, Marshall Weber, a certified personal trainer and owner of Jack City Fitness, says that he’s “definitely been surprised by the growing push towards unplugged fitness,” but that he “totally gets it.” Weber says he’s had clients express feeling “overwhelmed with their Fitbit or Apple Watch micromanaging their training.” When every workout becomes about numbers and keeping up with an average, it’s all too easy to lose touch with your body. “The anti-tech movement is about taking back that personal connection,” Weber says. After all, when was the last time you finished a workout and didn’t immediately look at your stats, but instead just noticed how you felt?
This is the paradox at the heart of fitness technology. Tools designed to help us understand our bodies have created a new kind of illiteracy. Maybe you can tell me why you’re aiming for Zone 2 workouts, but can’t actually recognize what that effort feels like without a screen telling you. In a sense, you might be outsourcing your own intuition to algorithms.
If nothing else, the data risks are real. (Because if you think you own all your health data, think again.) Every heart rate spike, every missed workout, every late-night stress indicator gets recorded, stored, and potentially shared. Still, for me, the more insidious risk is psychological: the erosion of our ability to know ourselves without consulting a device first.
What do you think so far?
How to unplug and exercise intuitively
So what does unplugged fitness actually look like in practice? It’s not about rejecting all technology or pretending GPS watches and heart rate monitors don’t have value—I promise. Look, I crave data and answers as much as—and maybe more than—the average gym-goer. I’m simply not woo-woo enough to ditch my Garmin altogether.
Instead, I argue for re-establishing a hierarchy in which technology serves your training, not the other way around. “Sometimes, the best performance boost is just learning to listen to what your body is saying and feeling,” says Weber. But what does “listening to your body” actually look like?
If you’re like me, and need to rebuild a connection with your body from the ground-up, try these approaches:
-
Start with tech-free workouts. Designate certain runs, yoga sessions, or strength workouts as completely unplugged. No watch, no phone, no tracking. Notice what changes when there’s no device to check.
-
Relearn your body’s signals. Can you gauge your effort level without looking at a heart rate monitor? Do you actually know what “recovery pace” feels like for you, or are you just matching a number? Practice assessing fatigue, energy, soreness, and readiness without checking your watch.
-
Replace metrics with sensory awareness. Instead of tracking pace, notice your breathing pattern. Instead of counting calories burned, pay attention to how your muscles feel. Instead of obsessing over sleep scores, ask yourself a simple question in the morning: how do I actually feel?
-
Set goals that can’t be gamified. Rather than chasing step counts or streak days, aim for qualitative improvements. Can you hold a plank with better form? Does that hill feel easier than last month? Are you enjoying your workouts more? These are the markers of real progress.
-
Create tech boundaries. Maybe you use your GPS watch for long runs but leave it home for everything else. Perhaps you track workouts but delete the social features. Find the minimum effective dose of technology that serves your goals without dominating your headspace.
-
Reconnect with in-person community. The loss of shared gym culture—people actually talking to each other instead of staying plugged into individual screens—represents more than just nostalgia. There’s real value in working out alongside others, in having conversations about training instead of just comparing data, in building knowledge through shared experience rather than algorithm-driven insights.
The bottom line
Unplugging is easier said than done, but you don’t need to go cold turkey. Maybe in the new year, you can set “body literacy” as a worthwhile resolution. At the end of the day, exercise should add to your life, not become another source of performance anxiety. It should be energizing, not exhausting—and I don’t just mean physically. The never-ending irony of modern fitness culture is that in our pursuit of optimal health, we keep inventing new forms of stress and anxiety. When all forms of wellness come with trackable metrics and social pressure, I think we’ve fundamentally missed the point.

How to avoid exercise burnout and still build muscle, according to an expert
Many of us have experienced the overwhelming feeling of mental and physical exhaustion that comes with exercise burnout. When you push yourself too hard without sufficient rest and recovery, it ultimately becomes counterproductive to your fitness goals, and your energy will tank along with your motivation. Not only that, your performance will suffer when you overtrain and under-recover, and you’re left sinking further into the couch, wondering how you’ll lift that next weight, swim that next lap, or run that next mile.
With a combo of the right nutrition, rest, recovery, and lowering your training intensity, you can get back on track. To learn more about avoiding burnout and torching fat while sculpting muscle for men, I asked certified personal trainer and Vice President of Education for Body Fit Training, Steve Stonehouse, to share some of his vast knowledge on the subject. With decades of experience in fitness education, fitness programming, and personal training, Steve Stonehouse developed an in-depth knowledge of weight loss, improving body fat composition, building muscle, and the best exercise plans that generate serious results.
Expert advice on burning fat
The Manual: As the Vice President of Education for Body Fit Training, what are your top tips for burning fat and improving body composition for men?
Steve Stonehouse: As the programmer and head of education, this is a little cliché, but I go for balance. Not every workout can be this CrossFit type, give it all you’ve got, smoke yourself, and work out — that’s not sustainable. The other end of the spectrum is just walking at a moderate pace for 20 minutes on a treadmill three times a week, because that’s not going to do it either. There’s value in both of those scenarios.
It’s best to have a session or two each week where the intensity is very high, and you’re testing yourself and pushing yourself closer to your limits. That’s anaerobic exercise, which is 90% intensity or above. It’s fine, safe, and healthy to get there occasionally, but every workout can’t be one of those. Your body isn’t built to train that way; you’re gonna burn out, and you could get injured, or both.
There’s a place for some moderate intensity as well, so if I were focusing on heart rate, I would say in the 80s, so it’s hard but not max effort, and it’s more sustainable. When you’re in that 70 to high 80s range, we categorize that as building aerobic capacity. Overall, I suggest an approach with recovery, moderate intensity, and then high intensity every now and again to test yourself.
The best cardio for fat loss
TM: How does cardio help with fat loss, and what types of cardio do you recommend?
Steve Stonehouse: I’m a big fan of high-intensity cardio. Sometimes, people think if some is good, more is probably better, but more isn’t always better. If I were putting a program together for six days a week, I’d have three days as some type of cardio-driven day, and three of those days I would have some version of resistance training. Maybe some days are heavier, and other days are a little lighter with higher rep targets and less rest.
Of those three cardio days, I’d recommend that one of them be a high-intensity max effort type HIIT session. Another could be hard with a heart rate in the 80s, but not max effort. That third cardio day could be more metabolic conditioning, like kettlebell swings, sled pushes, rower, or SkiErg, and things like that.
Ramping up muscle growth
TM: What types of exercise are the most effective for ramping up muscle growth?
Steve Stonehouse: We’re moving into a great space right now in fitness, and it seems like every 10 or 15 years, there’s this new movement. CrossFit first popped up and led the charge for metabolic conditioning and no days off. It’s the idea that if you still feel good at the end of a workout, you didn’t train hard enough. I think we’re phasing out of that and into wanting to lift heavy again. People who wouldn’t have touched a barbell ten years ago are lifting heavy now.
Keep in mind that heavy is a relative term. You can get stronger with some lighter dumbbells, but there are limits to that. A blend is nice, but you do need to include those times when you’re lifting heavy and challenging yourself at a low rep target.
Say, I’m going to do barbell deadlifts for five reps. If I can do eight, then that weight is too light. It’s intended to be a weight that you can’t get 15 reps of. There are advantages to lifting heavy with low-rep targets and longer rest times. For example, we’re going to do four sets of five reps of barbell deadlifts with two minutes of rest in between sets. If you can do more than five or six reps, that weight is too light. There’s a lot of value in lifting heavy.
TM: We know it’s probably difficult to choose, but what are your top three favorite fat-burning, muscle-building exercises right now?
Steve Stonehouse:
- Barbell Zercher squat
- Barbell deadlift
- Flat barbell bench press
TM: How often should you work out to build muscle?
Steve Stonehouse: For the heavy session with five or six reps and longer rest periods, you could have a day each week that’s primarily focused on upper-body heavy strength training. Then, you could split it up and have another day that’s primarily focused on the lower body. You could do that, so you’re not in the gym for two hours; it’s more like a reasonable 45 or 50 minutes. If you were feeling ambitious, you could get a third one in toward the end of the week and have a bit of a mixed session where there’s not as much volume, but you have upper-body and lower-body focus.
With that type of heavy volume, you’re going to need a decent amount of time to rest. So, if I were doing a heavy bench press today, I probably wouldn’t do that again until next week — same thing with squats, deadlifts, or any larger main lifts.
Incorporating sufficient rest days and progressive overload
TM: Are rest days important for the best results?
Steve Stonehouse: Yes. Rest and recovery are two different things. A recovery session would include a bit of activity, but at a lower intensity. Recovery is restoring to a natural, healthy state, and rest is inactivity.
TM: With resistance training, do you recommend incorporating progressive overload, where you gradually increase the weights over time to develop muscle strength and mass?Steve Stonehouse: 100%. We do strength training regularly at BFT. We have a portion of our performance app, and you can enter your five-rep max. On different days, the performance app tells you how much weight you should be lifting on that day to appropriately follow that progressive overload model.
