Exercise Is The Strongest Medicine

IT’S GREAT TO see Robert F. Kennedy Jr elevating exercise in the national conversation, and at Men’s Health we’ve been saying exercise is strong medicine for 35 years—because nothing advances health and can’t be patented by Pharma as much as consistently working out.

We’ve been reporting on the styles of strength and fitness that you need to optimize your health for years—and the pandemic, which saw those who struggled with fitness suffer more than strong, healthy people, put a spotlight on that. Since then, gym memberships are booming; 2023 saw with 72.9 million people with gym memberships.

These days, healthspan (the portion of life during which you’re able to do what you want instead of being frail and weak) is a buzzword, as we’ve covered in our stories with Peter Attia, M.D., author of Outlive: The Science and Art of Longevity. According to Attia: “Exercise is by far the most potent longevity ‘drug.’ The data are unambiguous: Exercise not only delays actual death but also prevents both cognitive and physical decline better than any other intervention. It is the single most potent tool we have in the health-span-enhancing toolkit—and that includes nutrition, sleep, and meds.”

Over the years MH has covered the ideal amount of exercise people should do, and, like Dr. Attia, MH recommend more exercise weekly—ideally 7 to 10 hours— than the government’s regulations. Currently, the CDC says:

Adults need at least 150 minutes of moderate-intensity physical activity a week. There are multiple ways to break this up, but an easy way to think about it is that you should fitness 30 minutes a day, 5 days a week.

Adults also need 2 days of muscle-strengthening activity each week.
The CDC does also note that you’ll gain even more health benefits if you go beyond 150 minutes of moderate-intensity activity or week – or if you have 75 minutes a week of vigorous-intensity activity (think: a pickup hoops game).

The latest research reveals that you need a combination of different intensities of cardio, as well as consistent strength training and stability exercises to be your best self. Here’s how much you should get to be at your best.

Your Cardio Goals

4+ Hours/Week

Dr. Attia says your VO2 max is a good proxy measure of physical capability: It indicates what you can—and cannot—do. Studies suggest that VO2 max will decline by roughly 10 percent per decade after your 20s and up to 15 percent per decade after age 50. Increasing your VO2 max makes you functionally younger. So having average or even above-average VO2 max has long-term ramifications. Dr. Attia’s goal for his patients is to be at an excellent level for the decade (or two) below their age. Many smartwatches can estimate VO2 max, but a real test (e.g., the Cooper 12-Minute Run) is better and VO2-max charts are easy to find online.

The good news?

You can improve VO2 max by as much as 17 percent per year. But you need to put in the work. Dr. Attia advises that patients do at least three 45 to 60-minute cardio sessions per week in zone 2 of their heart rate (57 to 65 percent of max heart rate, a gentle intensity during which you can say a complete sentence). They can involve running, cycling, rowing, even rucking. This is optimal for the health and efficiency of your mitochondria, the factories that burn fat and glucose to power your muscles and that decline as you age.

Along with cruising in zone 2, Dr. Attia recommends that patients do a weekly 30-minute VO2-max effort, such as high-intensity intervals that last anywhere from 3 to 8 minutes. For instance, you can run, ride, row, or ruck uphill for four rounds of four minutes, with four minutes of rest in between. “This is a much higher level of intensity—a hard, minutes-long effort,” he says. By testing your VO2 max and committing to cardio, you can nudge up your score and win in the long run.

Your Strength Goals

3+ Hours/Week

Age-related muscle loss—which starts insidiously in your 40s and picks up the pace in your 50s—is called sarcopenia, from the Greek words for “poverty of the flesh,” says Dr. Attia. Think of strength training as a form of retirement saving, he says. Just as you retire with enough money saved up to sustain you for the rest of your life, you want to reach an older age with enough of a “reserve” of muscle to protect you from injury and allow you to continue to pursue the activities that you enjoy. That muscle also acts as a buffer against the natural age-related decline in muscle mass. The larger the reserve you build up early on, the better off you will be over the long term. And, there are many categories to train:

Grip Strength

New research reveals that American adults have far weaker grip strength—and thus less muscle mass—than they did even a generation ago. In 1985, men ages 20 to 24 had an average right-handed grip strength of 121 pounds, while in 2015, men of the same age averaged just 101 pounds. Dr. Attia notes that many studies suggest that grip strength predicts how long you are likely to live. In these studies, it’s acting as a proxy for overall strength, but it’s also a broader indicator of general robustness and your ability to protect yourself if you slip.

Try These: Weighted carries, dead hangs, and plate pinches. Your goal: Do a farmer’s carry with a quarter of your bodyweight in each hand for one minute.

Concentric and Eccentric Loading

You need strength when your muscles are shortening (concentric) and lengthening (eccentric) under load. In other words, you must be able to lift the weight up and put it back down, slowly and with control. In life, especially as you age, eccentric strength is where many people falter.

Eccentric strength in the quads is what gives us the brakes required when we are moving down an incline or walking down a set of stairs. It’s really important to keep us safe from falling.

Try These: Focus on the “down” phase of lifts, whether doing pullups, curls, or deadlifts. Practice slow stepdowns—can you step off an 18-inch box in three seconds or more?

Pulling Motions

Pulling motions help bulletproof your shoulders against injury, and they’re critical in other underrated ways, too, driving your motion when you open car doors, lift boxes from the floor, and give somebody a hug.

Try These: Practice pulling at all angles. Start with dumbbell rows and progress to overhead moves like pullups.

Hip Hinges

You bend at the hips—not the spine—to harness your body’s largest muscles, the glutei maximi and the hamstrings. It is a very powerful move that is essential to life. If you are jumping, picking up a penny off the sidewalk, or simply getting out of a chair, you are hip hinging.

Try These: Deadlifts, hip thrusts, and kettlebell swings.

With all this exercise, your body may need more TLC. And that’s where stability and mobility training and low impact things like yoga and walking come in. These kinds of activities help your body recover and you can target weak areas to build your overall strength.

If you need somewhere to start and aren’t sure how to get going: Try this simple bodyweight workout: Set a timer for 10 minutes. Start by doing 30 seconds plank walkout, then do 30 seconds of alternating reverse lunges, then do 30 seconds of jumping jacks. Rest 30 seconds, then repeat until time is up. This simple session fires up your core and burns calories, and it gets you moving in multiple planes, an underrated quality you want to preserve for longevity. It also challenges many of the key functions we’ve already listed above. A bonus: As you gain fitness, this can become a warmup drill for any workout you do.
