How To Do HIIT (Without Wrecking Your Body)
How to Do HIIT Safely and Effectively. HIIT is a research-backed exercise approach that offers unique health benefits, including calorie burning, increased metabolism, fat loss, and more.
How To Do HIIT (Without Wrecking Your Body)
High-Intensity Interval Training, henceforth “HIIT”, is a well-researched and well-evidenced approach to exercise that gives powerful health benefits.
Specifically, health benefits that we don’t get from moderate exercise (as important as that is too) or endurance training.
Super-quick overview of the benefits first:
- Burns more calories than other forms of exercise
- Boosts your metabolic rate for hours afterwards
- …which means it actually works* for fat loss
- Reduces blood pressure (unless already healthy)
- Can promote muscle growth (depends on other factors)
*remember that most forms of exercise aren’t very good for fat loss, because our metabolism will slow afterwards to compensate. So HIIT flipping this one is quite a big deal.
What actually is it?
HIIT means exercise sessions in which one alternates between high intensity “maximum effort” bursts, and short recovery periods during which more moderate exercise is performed.
An example for runners could be switching between sprinting or jogging, changing mode each time one passes a street light.
❝A total of only two minutes of sprint interval exercise was sufficient to elicit similar responses as 30 minutes of continuous moderate intensity aerobic exercise❞
What did you mean about not wrecking your body? Is that… Likely?
Hopefully not, but it’s a barrier to some! We are not all twenty-something college athletes, after all, and our bodies aren’t always as durable as they used to be.
HIIT relies on intense exercise and short recovery periods, but what if our bodies are not accustomed to intense exercise, and need longer recovery periods? Can we still get the same benefits?
The trick is not to change the intensity or the recovery periods, but the exercise itself.
For HIIT to work the “intense” part has to be best-effort or approaching such. That part’s not negotiable. The recovery periods can be stretched a bit if you need to, but with the right tweaks, you ideally won’t have to do that.
Great! How?
First, note that you can do resistance interval training without impact. For example, if you crank up the resistance on an exercise bike or similar machine, you will be doing resistance training along with your cardio, and you’ll be doing it without the impact on your joints that you would if out pounding the pavement on foot.
(Running is fine if your body is used to it, but please don’t make HIIT your first running exercise in a decade)
Second, consider your environment. That exercise bike? You can get off it any time and you’re already at home (or perhaps your gym, with your car outside). Not so if you took up mountain biking or road racing.
Third, go for what is gentle in motion, even if it’s not resistance work per se. Swimming is a fabulous option for most people, and can absolutely be done with HIIT principles. Since vision is often obscured while swimming, counting strokes can be a good way to do HIIT. For example, ten strokes max effort, ten strokes normal, repeat. Do make sure you are aware of where the end of the pool is, though!
Fourth, make it fun! Ok, this one’s not about the safety quite so much, but it is about sustainability, and that’s critical for practical purposes too. You will only continue an exercise routine that you enjoy, after all.
- Could you curate a musical playlist that shifts tempo to cue your exercise mode intervals?
- Could you train with an exercise partner? Extra fun if this has a “relay race” feel to it, i.e. when one person completes a high intensity interval, the other person must now begin theirs.
Need some pointers getting started?
There are a lot of HIIT apps out there, so you can just search for that on your device of choice.
But!
We at 10almonds have recommended 7-Minute Workout before, which is available for iOS and for Android, and we stand by that as a great starting choice.
Enjoy!

Stop Cancer 20 Years Ago
Dr. Jenn Simmons shares vital tips on preventing cancer and inflammation, advocating for lifestyle changes and proactive health management at any age.
Get Abreast And Keep Abreast
This is Dr. Jenn Simmons. Her specialization is integrative oncology, as she—then a breast cancer surgeon—got breast cancer, decided the system wasn’t nearly as good from the patients’ side of things as from the doctors’ side, and took to educate herself, and now others, on how things can be better.
What does she want us to know?
Start now
If you have breast cancer, the best time to start adjusting your lifestyle might be 20 years ago, but the second-best time is now. We realize our readers with breast cancer (or a history thereof) probably have indeed started already—all strength to you.
What this means for those of us without breast cancer (or a history therof) is: start now
Even if you don’t have a genetic risk factor, even if there’s no history of it in your family, there’s just no reason not to start now.
Start what, you ask? Taking away its roots. And how?
Inflammation as the root of cancer
To oversimplify: cancer occurs because an accidentally immortal cell replicates and replicates and replicates and takes any nearby resources to keep on going. While science doesn’t know all the details of how this happens, it is a factor of genetic mutation (itself a normal process, without which evolution would be impossible), something which in turn is accelerated by damage to the DNA. The damage to the DNA? That occurs (often as not) as a result of cellular oxidation. Cellular oxidation is far from the only genotoxic thing out there, and a lot of non-food “this thing causes cancer” warnings are usually about other kinds of genotoxicity. But cellular oxidation is a big one, and it’s one that we can fight vigorously with our lifestyle.
Because cellular oxidation and inflammation go hand-in-hand, reducing one tends to reduce the other. That’s why so often you’ll see in our Research Review Monday features, a line that goes something like:
“and now for those things that usually come together: antioxidant, anti-inflammatory, anticancer, and anti-aging”
So, fight inflammation now, and have a reduced risk of a lot of other woes later.
See: How to Prevent (or Reduce) Inflammation
Don’t settle for “normal”
People are told, correctly but not always helpfully, such things as:
- It’s normal to have less energy at your age
- It’s normal to have a weaker immune system at your age
- It’s normal to be at a higher risk of diabetes, heart disease, etc
…and many more. And these things are true! But that doesn’t mean we have to settle for them.
We can be all the way over on the healthy end of the distribution curve. We can do that!
(so can everyone else, given sufficient opportunity and resources, because health is not a zero-sum game)
If we’re going to get a cancer diagnosis, then our 60s are the decade where we’re most likely to get it. Earlier than that and the risk is extant but lower; later than that and technically the risk increases, but we probably got it already in our 60s.
So, if we be younger than 60, then now’s a good time to prepare to hit the ground running when we get there. And if we missed that chance, then again, the second-best time is now:
See: Focusing On Health In Our Sixties
Fast to live
Of course, anything can happen to anyone at any age (alas), but this is about the benefits of living a fasting lifestyle—that is to say, not just fasting for a 4-week health kick or something, but making it one’s “new normal” and just continuing it for life.
This doesn’t mean “never eat”, of course, but it does mean “practice intermittent fasting, if you can”—something that Dr. Simmons strongly advocates.
See: Intermittent Fasting: We Sort The Science From The Hype
While this calls back to the previous “fight inflammation”, it deserves its own mention here as a very specific way of fighting it.
It’s never too late
All of the advices that go before a cancer diagnosis, continue to stand afterwards too. There is no point of “well, I already have cancer, so what’s the harm in…?”
The harm in it after a diagnosis will be the same as the harm before. When it comes to lifestyle, preventing a cancer and preventing it from spreading are very much the same thing, which is also the same as shrinking it. Basically, if it’s anticancer, it’s anticancer, no matter whether it’s before, during, or after.
Dr. Simmons has seen too many patients get a diagnosis, and place their lives squarely in the hands of doctors, when doctors can only do so much.
Instead, Dr. Simmons recommends taking charge of your health as best you are able, today and onwards, no matter what. And that means two things:
- Knowing stuff
- Doing stuff
So it becomes our responsibility (and our lifeline) to educate ourselves, and take action accordingly.
