90 Minutes a Week Could Add Years to Your Life — and Most People Do Zero

It’s 6:40 on a Tuesday. Mark is sitting in his car in the gym parking lot, engine still running, scrolling his phone. He’s 38. He’s been meaning to “start lifting” for about four years now. The membership has been auto-charging his card the whole time. He’s used it maybe nine times. Tonight he drives home again.

If you’ve ever been Mark, this one’s for you. The science just changed, and it’s good news for the people who do the least.

The study that should be on every fridge in Madison

In June 2026, researchers at the Harvard T.H. Chan School of Public Health published one of the largest looks ever at strength training and how long people live. They tracked 147,374 people for up to 30 years. That’s not a small lab study. That’s a small city, followed for three decades.

Here’s the headline. People who did just 90 to 120 minutes a week of strength work had a 13% lower risk of dying from any cause , a 19% lower risk of dying from heart problems, and a 27% lower risk of dying from brain diseases like Alzheimer’s. (Strength work here means anything that makes your muscles work against resistance: pushups, squats, lunges, lifting weights.)

Read that 90-minute number again. That’s about 13 minutes a day. Less time than you spend deciding what to watch.

And when people added some cardio on top of that strength work, the payoff climbed to around 45% lower risk of early death compared to people who did neither. The full study ran in the British Journal of Sports Medicine.

The real problem isn’t that you’re overdoing it

Here’s where most fitness articles get it wrong. They tell you to relax, you don’t need to live in the gym. True, but useless. Almost nobody is overdoing it.

The actual problem is the opposite. According to the CDC, about 60% of U.S. adults do zero muscle-strengthening activity in a typical week. None. Six in ten. And only about 22.5% of adults hit both the strength and the cardio targets.

So this isn’t a story about cutting back. It’s a story about going from nothing to something. The jump from zero to 90 minutes is the most valuable move in health you can make. It’s also the one most people never make.

That gap is where Mark lives. It’s where a lot of us live. The question isn’t “how do I optimize my routine.” It’s “how do I become a person who actually shows up.”

Why the barbell loses people

Let’s be honest about why Mark drives home. Lifting weights, for most beginners, is boring. You do a set. You wait. You check your phone. You do another set. You drive home and do it again Thursday, if you go.

The numbers back this up. Roughly 60% of new gym members quit within the first year , and the top reason isn’t cost. It’s monotony and the lack of a real routine. We’ve written before about why most gym-goers quit and the one fix that works . The short version: willpower runs out, but a community you’d feel bad ditching doesn’t.

That same research found that group and social fitness keeps people training far better than going it alone. New skills, novelty, and a sense of belonging are what bring people back. There’s a reason your treadmill habit died and your group-chat habit didn’t. We dug into that pull in the admin-night effect .

So the move isn’t to white-knuckle your way through a routine you hate. It’s to pick something you’ll actually come back to.

Where Brazilian Jiu-Jitsu fits

Here’s the part nobody tells the Marks of the world.

Brazilian Jiu-Jitsu (a grappling martial art — think wrestling that ends in submissions, no punching) hits that strength stimulus the Harvard study is talking about. But it does it through real, full-body movement instead of isolated machine reps. You’re not curling a dumbbell. You’re holding position against a resisting human, gripping, bridging, framing, controlling. Your back, grip, shoulders, hips, legs, and core all work at once. A lot of it is isometric — holding tension without moving, like the bottom of a plank — which is exactly the kind of muscle work that counts.

Then there’s the cardio. This is the surprising part: you get way more cardio out of a BJJ class than you do out of a lifting session. During live rolling — the part of class where you actually spar — your heart rate sits around 164 beats per minute, roughly 85% of max, and stays there . A hard set of squats touches that number for a few seconds on the last rep. A round of jiu-jitsu holds it for five straight minutes.

That same research review found trained BJJ athletes carry the kind of aerobic fitness (your body’s ability to use oxygen during sustained effort) you’d expect from a serious endurance athlete. A match-physiology study describes it well: rounds blend steady aerobic work with hard anaerobic bursts, the whole body moving through different angles the entire time. It’s a mixed workout by design. If you want the deeper dive on the cardio side, we made the case for why jiu-jitsu burns fat better than steady-state cardio .

So you get the resistance stimulus the study rewards, plus more cardio than the weight room, plus a skill that changes every single session.

Let’s be fair to the barbell

I won’t oversell this. If your goal is a max deadlift or building the most muscle possible, structured weight training wins. It lets you add a little weight every week in a measurable way, and nothing matches that for pure strength and size.

But that’s a problem for the 3% chasing a personal record on their deadlift. It is not the problem facing the 60% doing nothing at all. For that person, the best workout isn’t the perfect one on paper. It’s the one they’ll still be doing in a year. As the Harvard team’s Edward Giovannucci put it: “For people who are less active, the key message is that small amounts can still matter. Building a routine gradually may be more important than trying to do a lot at once.”

You can always add targeted lifting later. Plenty of our members do. Start with the thing that gets you off the couch first.

“But I’m out of shape and I’ve never done this”

Good. That means you’re exactly who BJJ is built for. You don’t need to be fit to start — you get fit by starting. We answered that worry head-on in should I get in shape before beginning BJJ , and the answer is no, you come as you are.

Our adult classes in Madison are filled with working professionals and parents, not cage fighters. At Journey, adult classes skip the warmup and go straight into technique, broken into small steps a beginner can follow. Every class is different, you’ll burn around 500 calories without watching a clock, and nobody expects you to be good on day one. If you want to know exactly what walking in feels like, here’s how to prepare for your first BJJ class .

Three things you can do this week

You don’t need us to get healthier. Start here, today:

1. Do 90 minutes of resistance work this week, split however you like. Three sessions of 30 minutes. Bodyweight counts — pushups, squats, lunges, planks. That’s the whole Harvard dose. No equipment, no excuse.
2. Stack it onto something you already do. Ten squats while the coffee brews. A two-minute plank-and-pushup set after your shower. Giovannucci’s point was to build the routine slowly, so anchor it to a habit you’ve already got.
3. Try the thing you’ll actually stick with. If the weight room bores you, that’s not a character flaw, it’s a signal. Find a class, a sport, a group — something with people and a little novelty. The best workout is the one you don’t quit.

And if you want that “something” to be jiu-jitsu, come see the room before you commit to anything. Book a free, no-pressure meeting with Coach Alex — you’ll tour the facility, learn how the classes work, and decide for yourself. No sales pitch, no obligation.

You don’t have a researcher’s 30-year study to run. You have a Tuesday at 6pm. That’s enough.
