When the British Journal of Sports Medicine published a paper1 a few weeks ago showing a long-term correlation in older adults between strength training and living longer, many media dutifully reported the intriguing main finding: just 90 to 120 minutes per week of resistance exercise was linked to:

• a 13% lower risk of all-cause mortality (ie, risk of dying from any cause)

• a 19% lower risk of cardiovascular mortality (dying from heart-related causes)

• a 27% lower risk of neurological disease mortality (dying from dementia, etc.)

Mortality risk means the chance of dying; the bigger the percentage decrease in that risk, the greater the impact on longevity. As obvious or intuitive as it might seem to some people, moving your body against weighted resistance, this study suggests, could play a significant role in helping you live longer.

But it doesn’t compare to cardiorespiratory training, and that’s one giant takeaway that nearly all the media posts on this longevity paper didn’t mention:

Cardio alone was associated with a 26% to 43% lower risk of death, compared with people who did neither cardio nor strength training.

That equates to a roughly 2x to 3x larger reduction in mortality risk than strength training alone. The study authors themselves acknowledged cardio as superior, stating on p. 881 of the journal: “[W]hile either sufficient aerobic or resistance training alone reduced mortality risk, aerobic activity conferred greater benefit”2 (italics mine).

Though not a novel declaration, it’s an important reminder that in the constellations of physical movements that may well help you live the longest, combining strength and cardio training creates greater benefits than either one does by itself. If you had to pick the exercise category with the single biggest longevity upside, aerobic fitness—affectionately abbreviated in our culture as VO2 max—is king of the exercise hill.

The paper also concluded that respondents who regularly did strength and aerobic training had up to 45% lower mortality risk than people who did little-to-no exercise.

The big takeaway: “For people who are less active, the key message is that small amounts can still matter,” said Edward Giovannucci, a professor of nutrition and epidemiology at Harvard’s T.H. Chan School of Public Health and one of the study’s authors, in Harvard’s press release about the study. Also: “Building a routine gradually may be more important than trying to do a lot at once.”

But let’s look beyond only the headlines, at what this study also revealed, which you won’t find anywhere else—partly because most media reports on these results were cursory and/or misleading, and also because the full paper hasn’t been publicly released.

Other notable features from this Harvard longevity analysis

AGING with STRENGTH obtained, upon request, a copy of the full text of the paper from one of the Harvard-affiliated authors, on which the reporting below is based.

Other less obvious findings from the full-text of the paper include:

1. a counterintuitive ratio of exercise minutes per week to increased cancer risk

2. strength training’s association with reductions in neurodegenerative (ie brain) diseases may be overstated in the data, due to reverse causation

3. doing more minutes per week of strength + cardio training was linked to reduced longevity gains compared to more modest levels of training

4. a structural weakness in the resistance-training data reporting that arguably calls into question how accurate this paper’s analytical model is

I examine each of these in greater detail below. (If you’re interested in how this research was conducted, please read this footnoted explanation.3)

Where, how, how often and with whom you strength train is about as personal a fitness choice as there is. That choice, in my experience, tends to correlate not only to what you want your body to look like but also how you want to feel by the time you hit the showers.

Two different kinds of gym workouts

If the goal is to punch that timecard, execute your routine, lift the weight and book a gym win, your workouts tend to go in one direction. If the goal is more akin to rebooting your operating system by going long, hard and deep into your strengths, exhausting yourself into a palpable physical, mental and emotional restoration—well, then, your workout probably goes in a different direction.

I’ve spent years regularly going in that second direction, through supersets. Supersets combine strength training with aerobic and mental conditioning that, according to scientific research that bears out my experience, confer a unique set of physical benefits that regular gym workouts don’t.

Below, I explain the physiology of those gains and the cyclic compound effect they generate. I also describe my personal lower-body strength supersets routine that AGING with STRENGTH paying subscribers can use as a customizable blueprint to condition your all-important posterior chain, as well as your aerobic fitness and mental toughness.

What are supersets?

Supersets are more intense versions of regular workouts. The word superset refers to executing sets of two or three different exercises in rapid succession without much rest in between—and then repeating that cycle for an entire workout. Supersets may incorporate different muscle groups—legs and chest, for instance—or blend related exercises focused on just one muscle group.

With supersets you’re typically:

• lifting only 50% to 75% of your maximum…

• which enables doing more reps that build into a wall of fatigue…

• because you’re resting only 30-90 seconds between sets…

A muscular flow state

That’s how mental toughness enters the superset equation: when each set leaves you breathless, you don’t cool down; you keep going. Your mind must convince your body to hit the next set in the rotation as soon as your heart rate begins to settle, without losing proper form or technique.

You sweat a lot more, burning more fat than you do in a regular workout.

And, in a major breach of gym protocol nowadays, you don’t have time or desire to look at your phone in between sets. You’re in a muscular flow state.

In case you missed it…

Posterior-chain workouts are the ones I enjoy supersetting the most, because they’re the biggest and arguably most important muscle groups, and engaging body and mind to work them to sweaty exhaustion produces as close to a calming physical reset as you’re likely to experience in a public space. As we age, lower-body strength is the engine of our mobility and supports a powerful core.

Supersets are also just plain fun because they demand all your attention; you’re captivated. I admire and respect those regular gym workouts I described above, but I often can’t carve out regular workout times that make them a habit. So whenever I do have a glorious 90 minutes or more to work out, I tend to train in supersets.

Turns out, there’s no shortage of science to support the feelings I’m describing.

The unique advantages of training with supersets

Supersets do two useful things at once: they shorten the session and keep your heart rate up. When researchers compare combining exercises this way against the conventional one-lift-at-a-time approach, the muscle and strength gains come out about the same, while the combined version finishes in roughly a third less time.12 The 50–75% load is heavy enough to build muscle and light enough to keep moving while you tire, and that pairing—moderate weight, short rest—produced the biggest changes in a 45-study review: a 4.3% drop in fat mass, a 1.9% gain in muscle mass, and a 6.3% rise in VO2max.3

If you target the same group of muscles with supersets, fatigue within those muscles accrues, and you move less total weight than you would resting fully between straight sets. Thus, the harder sessions can demand longer recovery before you train those muscles again.4

The muscle-mental resilience superset cycle

There’s one more major advantage supersets offer that the literature doesn’t mention.

Cutting the rest between sets trains local muscular endurance and, over weeks and months, builds a fitter system—one that recovers faster between efforts and tolerates more discomfort before the urge to quit takes over.

Growing more tolerant of discomfort is the definition of mental resilience.

Your ability to endure discomfort yields a physical payoff that builds mental toughness. The toughness makes the next hard session more tolerable, which produces more physical gain, which feeds the toughness again.

This cycle yields and compounds, yields and compounds. You may find that it starts to show up in other areas of your life, away from the gym or fitness. If that sounds a bit Nietzschean, there’s a reason superset workouts require more recovery time than regular gym routines.

My lower-body superset routine: a triple-strength workout

Here’s my typical 90 minute posterior-chain superset routine, which hits several related muscle groups to build muscle, modestly increase VO2 max and train mental resilience.

I’ll describe the specific movements, the number of sets and amount of weight I use for each, and estimated resting times. This is not prescriptive but rather a template anyone can adapt and edit to their liking. Tune it to your body type and fitness goals.

I spent the last couple weeks thinking—and the last few days researching and writing—about sex. Specifically, sex after 50 and everything it offers and doesn’t offer. (If you’re in your 40s, you are, of course, welcome. There is plenty for you here, too.)

Sex after 50 is a vast and complicated subject, and writing about it wrong is incredibly easy. So I did what any self-respecting reporter with a perfectionist streak and a hearty interest in continual, lifelong sex would do: I dove into the data, all the data I could find, to see what grand portrait would emerge about how people have sex in midlife and beyond, how they fail to have sex and how they adapt—when they can’t get what they want—to at least get what they need.

The Aging with Sex special report

I put dozens of hours of reporting and fact-checking into the 10-page report below, which paying subscribers can access. The report covers 10 topics and offers a list of summary takeaways:

• How Often Are Older Adults Having Sex?

• The Types of Sex Older Adults Are Having

• Having Sex Is Good for Your Health

• Masturbation: Important, Protective and Healthy

• Polyamory and Consensual Non-Monogamy

• A 30-year Sex Recession (Thanks, Internet)

• Men: Erectile Dysfunction

• Women: Genitourinary Syndrome & Sexual Dysfunction

• Sex and Testosterone | Sex and Estrogen

• Major Barriers to Sex in Europe, Australia & Asia

• Takeaways: An Actionable Summary of the Data

How I reported it: I created this report by pulling together every credible study on sex after 50 I could find — 2015 through 2026, comprising a total of 39 footnoted sources. Then I ran it through more than a dozen rounds of fact-checking, with the help of two top-tier AI models I work with almost daily to analyze large data sets.

Sex does not stop at 50, and it’s good for your health

That’s the major headline of this report. Roughly half of adults in their 60s are still sexually active. But sex most definitely changes. Often the changes, whether from E.D., menopause, stress, or lack of a suitable partner, are navigable. For many many people of a certain age, sex becomes many things that are not intercourse.

The biggest barrier, according to the research, is partner availability and personal health. On a very bright note, the data now link regular sex to lower mortality, better cardiovascular markers, less depression, sharper memory.

The hitch in the story is that most older adults with a sexual problem never raise it and, apparently, most doctors rarely or never ask. That’s too bad, because many of the problems sex after 50 may present are treatable, by which I don’t mean just medically.

Over the coming weeks I’ll break down Aging with Sex into strategies, including:

• the cardio and strength exercises that most benefit good sex

• addressing E.D., estrogen and testosterone treatments

• what happens when traditional intercourse isn’t an option

Until then, here’s the 10-page Aging with Sex special report, which provides a foundation for all the above:

Physical strength is so important in the second half of life (and it’s never too late to start building it). But strength alone won’t keep you quick, agile and fully physically capable of handling unexpected challenges. You also need to develop power.

Strength and power are different abilities. And here’s a sobering statistic: Once you hit 50, muscle power declines roughly twice as fast as muscle strength.1 Power is something I’ve put more personal emphasis on lately. Below, I recommend several exercises that anyone in good health can do to build strong and powerful muscles. (At bottom, I’ve also included several power exercises for people with spinal issues).

What is “power” and why is it important?

Strength is your ability to move a heavy thing. Power is how fast you can move it. And here’s a twist that many mature athletes may not realize: Heavy strength training alone doesn’t produce meaningful power gains in older adults. You can squat twice your body weight (though I don’t recommend bar squats) but your vertical jump and chair-stand speed will barely move. The reasons are mechanical and neurological: heavy lifting trains the nervous system to produce force gradually. Power requires the nervous system to fire fast—to recruit type II fibers quickly and synchronously. Slow, heavy lifting does not.

That accelerated decline in muscle power after age 50 is, in large part, a fast-twitch fiber story, and that’s why gyms are full of strong people who haven’t trained for power. Power is what gives your muscles quickness, and quickness is what gives out first in daily life. Power, not raw strength, allows you to:

• get out of a low chair or off the ground

• catch yourself when your foot hits the curb

• climb stairs two at a time (without spilling a brimming glass of water)

• throw fast, jump high, punch/kick with force (or deflect punches and kicks)

• accelerate and decelerate

• snap a towel, pan-toss an omelette or lift luggage into an overhead bin

• catch a falling object (or return a wicked tennis or pickleball drop shot2)

Muscles don’t have to be big to be powerful. They just need to be trained to contract faster and generate force more quickly. Here’s how anyone—women and men, younger or older—can start building more fast-twitch muscle power.

15 power + strength workouts you can start doing now*

Power is moving a weight quickly. So to create more powerful muscle for longevity, the solution is pretty simple: move weight faster. You can adapt your existing workouts to do that, of course, using a “slow/down, fast/up” rhythm to any movement.

Here are 15 specific exercises (with a couple video clips) that you can do at home or the gym that are excellent for building functional power into your strength training. (Scroll to the bottom for power exercises for people experiencing spinal issues.)

• 9 of the 15 movements below have 🅗 after them, denoting exercises you can do at home with no equipment or almost no equipment

• The mace bell exercise shown the photo above is not among the 15 power exercises below, but it is a great workout. If there’s interest, I’ll create a post on it.

I have fond memories of my heavy squat sessions. They were often on Friday nights, when the gym was empty but for the true believers. The core of my routine was 8 sets of 10 reps of 225 pounds. The endorphins, the sweaty heart-rate spike and the iron-denominated gains in strength were addicting; the return to existential baseline real.

“The king of all exercises”

Weighted back squats are one of the most demanding compound movements there is, because they recruit multiple muscle groups and joints simultaneously. NFL players, powerlifters and generations of coaches and dedicated gym rats the world over swear by them. They’ve long been considered one of the most complete lower-body exercises. They’re good at making your butt and legs look great. And they show the world—quite literally—how much of it you can shoulder.

And you should probably quit doing them.

For most people over 50 (and, very arguably, anyone) bar squats are not the best way to achieve well-balanced, injury-free lower-body strength for the long haul. Back squats tend to exploit pre-existing structural problems in your hips, glutes and core and create the potential for insidious, slow-developing back, pelvic and knee injuries that, in midlife, become harder to heal.

Also, squats aren’t even the best way to make your butt look great.

To build lower-body strength, balance and stability, several other workouts beat squats, and I’ll get into those below. But first, the case against bar squats—and some context:

I know people love their bar squats. After 40-odd years, however, I reluctantly stopped doing them, once it became painfully clear how they were setting up my body for pain and injury. I know I’m not alone and, conversely, also that my experience isn’t universal and that lots of people love squats. Which is why I’m hoping you’ll….

The case against weighted back squats

My argument is simple: Though legendary, bar squats—especially at or above body weight—are an outdated way to build lower-body strength. Depending on how hard and heavy you go, I’ve come to think of them as the workout equivalent of petting the bison in Yellowstone National Park: kinda not worth the risk.

Bar squats create lumbar spine compression

When you descend into a loaded barbell squat, you put your lumbar spine under significant compression. One study, albeit from 41 years ago, demonstrated that at loads between 80% and 160% of body weight, the compressive force on the lumbar spine can reach 6 to 10 times body weight.1

Heavy bar squats combined with deep knee flexion, in particular, carry increased risks as discs L4-L5 (the primary load-bearing segments of the lower spine) and L5-S1 (the lowest movable segment) are being compressed and sheared simultaneously while in a mechanically disadvantaged position.2

Back squats exacerbate your accumulated asymmetries

Back squats tend to magnify the asymmetrical muscle development that almost all of us have to some degree—a slight lean to one side, one hip dropping slightly lower than the other, a tilted sacroiliac joint, one foot turned out more than the other. Over time, these asymmetries tend to concentrate stress on one SI joint more than the other, which is a common source of the chronic, hard-to-diagnose low back and hip pain that long-term heavy squatters—me included—often develop in their 40s and 50s.

Beware the asymmetric, tilted SI joint. When SI joints are continually stressed by asymmetrical loading under heavy compression, the surrounding ligaments and joint surfaces can become chronically irritated in a way that is genuinely difficult to treat and often misdiagnosed as a lumbar or hip problem.

This is where the insidious negative impact of bar squats can become a problem, because SI joint dysfunction tends to accumulate quietly and become a nagging problem—the low-grade but persistent pain that seems to live in the middle of your lower back that you can’t stretch or massage away. (Once again, I’m speaking from personal experience.)

Okay, but what about people who haven’t been damaged by four decades of heavy squats?

Other reasons to ditch loaded back squats

At 50 or older, mobility deficits tend to become baked in from decades of sitting, asymmetrical muscle imbalances and accumulated tightness. All these factors, I believe, argue against starting a new habit of squatting with a heavy bar on the back of your neck.

Hormonal changes that reduce the protective buffer. Particularly in women post-menopause, high-compressive loading of knees and hips under a barbell becomes a different proposition after 50 when hormonal support for ligaments, tendons and cartilage diminishes.

The human tendency to ego load. Who among us isn’t susceptible to throwing more weight on the bar in an attempt to impress everyone else in the gym, none of whom actually notice?

Joint pathology accumulates silently. Plenty of people in their 50s have cartilage degradation, meniscus degeneration or disc issues that don’t produce symptoms during most movements but can flare up under barbell squat mechanics.3 That footnote refers to a 2024 paper in the Journal of Functional Morphology and Kinesiology that identifies excessive arching of the spine and knee valgus (inward movement under load) as the two most common problems in older adults who do bar squats, creating the potential for injury, on top of all the other factors mentioned above.

In that regard, I’m pretty much Exhibit A for my argument to ditch bar squats. I can squat heavy, and my form may look fine at first glance. But as you watch the above video, notice how much my left knee wanders with each rep, relative to the red vertical line (my right knee also does but not as much). That’s knee valgus, likely a function of weak hip stabilizer muscles, including medial glutes.

Share

I hadn’t noticed that movement until I recorded myself, and for anyone who continues back squats, I recommend they do the same, from the front, side and rear, to understand exactly how their bodies may be compensating to manage the weight.

Further below, I offer a video of me doing a different weighted leg exercise that works the same muscles but without the lateral knee movement.

Don’t take just my word for it

As it turns out, some heavy hitters in the professional strength and conditioning world have come out in favor of ditching bilateral back squats. Here’s Mike Boyle, a renowned former strength & conditioning coach for the NHL’s Boston Bruins, the U.S. Women’s Olympic Ice Hockey Team and the Boston Red Sox, speaking in September on Peter Attia’s podcast (before Attia’s troubles) about why he moved away from training athletes on bilateral back squats:

Boyle argues against bilateral training in favor of unilateral strength work, which I was heartened to hear because it validated one of my favorite lower-body strength routines—it’s No. 3 in my list below.

6 better alternatives to squats for lower-body strength

If back squats work for you, and you love them and you’re convinced your form is excellent and you don’t want to give up the exercise, don’t. Just don’t go heavy.

But if you’re willing to consider better strength workouts for your legs and core, here are my top 6 strength workouts with explanations why I think each is superior to back squats.

The BLUF (bottom line up front): Research into the biology of long-living older adults reveals unique differences in so-called super agers and centenarians vs other people, and suggests what we can do to help us live longer, too.

The bodies and brains of very old and healthy people are roadmaps with some useful directions for people interested in aging with existential strength.

Two recent studies examined complementary facets of what separates so-called super agers—people who live well into their 80s in superb health—and centenarians from everyone else. Each report suggests that the biology of staying remarkably fit in body and mind may be far more flexible than most people over 50 have been led to believe.In other words: the new science supports the idea that moving your body with purpose daily, and feeding it whole food and clocking sufficient sleep, puts you in position for maximum healthy longevity. (For paying subscribers, here are several actionable recommendations to move and feed your body like its 1899).

What the centenarian & super ager studies revealed

The research on Swiss centenarians (press release here; scientific paper here) finds that certain 100‑year‑olds have blood protein patterns that look more like those of middle‑aged adults.

The new examination of brain tissue taken posthumously from “super‑agers” in their 80s (decent NYT summary here; scientific paper here) finds that they made roughly twice as many new brain cells as their peers, helping them keep unusually sharp memories.

Together these findings suggest that, even very late in life, the brain and body can stay far more youthful than we once thought.

There’s a saying in pro hockey: One shift at a time. It means focusing not on the ultimate goal—winning the game—but on winning only your next 45-second shift on the ice. Stacking small wins consistently is a proven strategy for achieving big goals.

The problem is that the Longevity Industrial Complex tries to convince you otherwise.

On Substack and a growing number of online media sites that have traded their credibility for say-nothing clickbait, wellness “experts” shill longevity through this one thing you should buy: a popular supplement, an expensive membership or a silly workout regimen featuring an AI image of a fake ripped 60-year-old.

As is often the case, though, the simplest solutions tend to be the most effective.

After more than a year of reporting on healthy longevity, I’ve collected a lot of thoughtful, actionable longevity advice from scientists, researchers, doctors, athletes, coaches, nutritionists and actual, ass-kicking older folks. Instead of spending your money on supplements and apps, they talk about a way of creating what I call practical longevity—one shift at a time.

Share

In its simplest form1, practical longevity boils down to three simple commitments.

Ignore most of what the Longevity Industrial Complex says

Commitment 1 — Stop trying to live to 100

A lot of “healthy aging” marketing tries to convince you longevity is measured in years—the more, the better—and can be acquired by credit card. Health & wellness chiselers2 tend to portray longevity as a competition you can win, if you just invest in their bullshit product, at their bullshit price, despite zero clinical evidence that it works in humans.

(Not all longevity supplements are scams, of course. Many show promise or straight-up work, and I’ve written and interviewed reputable scientists about several of them.)

Instead of focusing on reaching a certain age, cultivate the mindset of winning your current age one shift at a time. That’s the better way to “stack wins” (ie, healthy years) and end up a strong and sharp 88, 94, 103 or whatever number your Wheel in the Sky has in store for you.

You already have the facility, the means and, probably, the time to live healthy for as long as your body can — if you apply the discipline to build just two basic habits.

Warning: The two ideas I’m about to share are exceedingly simple in concept, and executing them as daily or weekly habits is exceedingly difficult if you don’t know why you want to. Before you start your practical longevity journey, take time to understand what’s motivating you. (Hint: “Looking better in the mirror” probably isn’t enough…unless it is.)

Dig past the surface rewards to ask yourself why healthy aging matters to you, really. Caveats aside, let’s get into these critical two commitments:

There are many fitness trackers out there. You probably have an idea of what brand, functionality, price tier and look and feel you prefer: Apple, Garmin, FitBit, Oura, etc.

I’m not here to change your mind. What follows, however, is a comparative chart of popular fitness tracker strengths and weaknesses that you can’t find through a normal online search or Wirecutter reviews.

The chart below, which paying subscribers can view and download, compares several different fitness trackers across a few metrics beyond device cost — such as:

• data accuracy

• health data privacy, ownership & jurisdiction (who owns your data & where it’s stored)

• app subscription comparisons and cost comparison over time

• water resistance (for swimmers, surfers and folks who run in the rain)

• notable privacy incidents (server breaches; ransoms paid, etc) for each company

• and more

The data privacy and ability to own your health data is a complex area that isn’t often covered by the (numerous) fitness tracker reviews you can find online. For example, one thing I learned researching the downloadable chart (for paying subscribers) below is that FitBit is now owned by Google — which means that Google also has access to, if not owns outright, all the health data it collects from your FitBit device.

Other, Chinese brands treat your health data as you would expect: it’s theirs now and thanks for donating.

The 4-page PDF below, containing a series of charts, covers all the information I mentioned in the above bullet points and presents fitness tracker information you can’t find in one place anywhere else. (NOTE: I used an upper-echelon, paid version of Claude.ai to research and compile this data…and spent several hours vetting it.)

Greetings—from my garage. Here’s the video (scroll down ￬) for paid subscribers that I promised in my most recent Saturday Coffee. Because so many of you asked for it, I decided to send it to all paying subscribers.

Perhaps the greatest benefit of working with rings is that they force your gym body to adapt to new forms of instability, to keep your weight centered and balanced on the rings. Thus, this workout builds muscles that regular gym weights and weight machines can’t. Talk about functional strength!

NOTE: This movement isn’t for everyone and requires some shoulder and triceps strength as well as some equipment, which I discuss in the video. But if you’re interested in developing upper-body strength in just one minute of daily movement, this simple rings movement works. It also builds six-pack abs in short order, I’ve found.
