How to fight Father Time: The 4 pillars of exercise for longevity

You never think it'll happen to your parents. But there I was, watching my 77-year-old mom struggle to get out of her favorite armchair. She'd always been active; but over the years, she began to decline. The pandemic isolated her, and the sudden slowdown activity began to take its toll.

"I just need a minute," she said, frustration clear in her voice. But a minute turned into five, and I realized this wasn't just a moment of weakness. This was the result of years of gradual muscle loss and decreased activity.

Have you ever worried about losing your independence as you age? Or watched a loved one struggle with simple tasks they once did effortlessly?

You're not alone. But there's hope.

The Silent Decline

Here's something that might surprise you: From age 25 onwards, we're all slowly losing muscle mass. It's a natural part of aging, but that doesn't mean we can't do something about it.

Let's break it down:

- From birth to 25, you're gaining muscle.

- From 25 to 75, you're slowly losing it (about 8-10% per decade).

- After 75, the loss accelerates dramatically.

But here's the kicker: It's not just about muscle. Activity levels fall off a cliff, too. It's all illustrated in these graphs from a study published in the American Journal of Clinical Nutrition.

Muscle mass and activity level decline steadily from 25-75, and precipitously after that.

Think of it like a seesaw. Less muscle means less strength … and less activity. Less activity means less muscle. It's a cycle that can be hard to break.

But what if I told you there's a way to keep that seesaw balanced, even as you age?

The Four Pillars of Lifelong Fitness

Enter what longevity expert Dr. Peter Attia calls the four pillars of exercise. They're your secret weapon against age-related decline:

1. Stability

2. Strength

3. Aerobic efficiency

4. Peak aerobic output

"Wait," you might be thinking, "I walk every day. Isn’t that enough exercise?" Not by a long shot. Walking is essential, too … but not at the expense of any of these pillars if you want to stay active and independent as you age.

Strength training is vital for longevity, regardless of your age.

Let's break them down.

Stability: It's Not Just About Balance

When you hear "stability," you might think of standing on one leg. But it's so much more. Stability is about:

- Dissipating force safely

- Maintaining balance

- Improving flexibility

Think of stability as the foundation of a house. Without it, everything else crumbles.

Strength: Your Life Preserver

Strength training isn't just for bodybuilders. It's your best defense against muscle loss. Regular strength training can:

- Preserve muscle mass

- Strengthen bones

- Improve metabolism

Remember: If you’re inexperienced, start with bodyweight exercises first before progressing to weights.

Aerobic Efficiency: Your Daily Energy Booster

This is all about improving your body's ability to use oxygen efficiently. It's what helps you:

- Climb stairs without getting winded

- Play with your grandkids without tiring

- Enjoy long walks with friends

The key? Consistent, moderate-intensity exercise like brisk walking or cycling so you can build a wide aerobic base.

Peak Aerobic Output: Your Health Insurance Policy

Think of this as your body's maximum capacity for exercise. It's important because:

- It's a strong predictor of longevity

- It improves your overall fitness

- It helps you handle life's unexpected physical challenges

When it comes to cardio, walking alone isn't enough if you want to be active when you're older.

High-intensity interval training is great for this, but always start slowly and progress gradually.

Starting From Scratch (Or Starting Over)

Now, you might be thinking, "This sounds great, but I haven't exercised in years. Where do I start?"

Don't worry. The most important thing is to start somewhere. Here's how:

1. Start with walking. Aim for 5,000 steps a day on flat ground.

2. Add some weight. Once you're comfortable walking, try carrying a light backpack. This is called "rucking" and it's great for building strength and stability.

3. Try bodyweight exercises. Wall sits, box squats, and push-ups against a wall are all great options.

4. Focus on quality, not quantity. It's better to do a few exercises with good form than many with poor form.

5. Be consistent. Aim to do something active every day, even if it's just a short walk.

Remember: Progress, not perfection. Every step counts.

The Long Game

Once you’ve developed some stability, strength, aerobic capacity and confidence, it’s time to ramp up the intensity. It’s important to check with your doctor before starting an exercise program. Once your doctor gives you the green light, it’s important to work with a trainer who has experience with clients your age so you maximize your results in a safe, injury-free way.

Studies show that people who lift relatively heavy weights maintain their strength and muscle function better than those who lift light weights or not at all.

You don’t have to be Mr. or Ms. Olympia, but studies have shown that people who lift weights that are relatively heavy for them (about 60-80 percent of their one-rep max) maintain their lean mass and muscle function better than those who lift light weights or not at all. Interestly, this was even shown to be true for several years after the subjects stopped lifting weights!

As far as “cardio,” the importance of having a high VO2 max – the amount of oxygen you can consume during intense exercise – cannot be overstated. The data show that in order to be capable of more than just walking on flat ground when you’re over 75, you need a VO2 max of a person two decades younger than you at an elite level when you are in middle age! 

And you’re not going to achieve a high enough VO2 max in your 50s, for example, simply by walking. This can only be achieved through consistent bouts of intense exercise, preferable under the guidance and supervision of a knowledgeable trainer.

So yes, you should take it slow in the beginning. But eventually, the weights need to be heavy and the cardio needs to be intense to achieve the desired results.

The Long-Term Payoff

Sticking with an exercise routine that incorporates all four pillars can:

- Help you maintain independence

- Reduce your risk of falls and injuries

- Improve your overall quality of life

- Keep you doing the activities you love for years to come

Think of it as akin to saving for retirement. It’s never too late to start … but the sooner you start, the better.

Your Next Step

Remember the story about my mom? After her wake-up call, she started a simple strength training routine. It wasn't easy at first, but she stuck with it. Six months later, she was not only getting out of her chair easily but also climbing stairs and taking care of her yard with ease..

You have the power to write your own story. Will you let age slowly chip away at your abilities? Or will you fight back, one step at a time?

The choice is yours.
