Should You Do Chair-Based Exercises?

/in /by

There are two more questions on the benefit of the chair-based exercises for getting stronger and getting ripped while doing it.

Will Chair-Based Exercise Increase Muscle Mass?

Examining the research on the benefits of chair-based exercise for increasing muscle mass seems clear. It will not—at least not to the degree the chair-based exercise ads suggest. People, specifically those over 60, will gain some strength that will help with balance and increase flexibility, but there’s no evidence it will increase muscle mass to any degree. I think that makes chair-based exercise beneficial for most people at some point in their lives.

And, by the way, how are those thighs feeling after doing one maximum set of squats every day by standing up and sitting down in a chair?

Should Men Over 50 Avoid Strenuous Exercise?

No. Whether it’s lifting weights or running a 5K, there’s no evidence that intense exercise is only for the young. What I think they were heading for was preventing age-related muscle loss called sarcopenia. Limited data shows that weight training can slow down muscle loss or reverse the loss somewhat, but it involves lifting weights, not chair exercises.

The intensity of your exercise program should always be dictated by discussions with your physician or physical therapist to plan your exercise path according to any cardiovascular disease, metabolic, or orthopedic issues you have. Chair exercises are definitely beneficial in helping you live your life, but looking lean and ripped is not going to happen. (That dream guy in the image is created with AI.)

The Problem

The companies that are promoting the apps related to chair exercises are doing a genuine disservice to potential customers. It’s a classic bait-and-switch. What they’re really promoting is intermittent fasting, focusing on the keto or Paleo diets, and tracking everything: food, exercise, sleep, and more. They offer chair exercise programs, but they begin easy. I’ve seen some of the videos later in the program, and the increase in intensity will make it difficult for people to keep up. That’s not going to happen in 15 minutes a day.

One more thing? The people in the videos are AI-enhanced. I thought something was off, but now, in very faint letters in a very small font, the use of AI-enhanced actors is admitted in the ads.

Chair-based exercise programs are legit and a great way to begin resistance training or to maintain your strength while you’re temporarily sidelined, such as after twisting an ankle. Consider it for 2026, but remember there are no quick fixes or ways around improving your health: you have to eat better, eat less, and move more.

What Is Chair-Based Exercise?

/in /by

Time marches on and we’re counting down to the New Year; it’s time to start planning how you’re going to maintain health and fitness if you have it or improve it if you could do better. Recently, especially on click-bait websites, there are a couple of companies that are pitching chair-based exercises as a solution to increase muscle and lose weight. “Only 15 minutes per day” they say and seem to imply you can have a body that’s ripped and toned. It’s tempting.

Part of the pitch is that after 50, men should be doing more resistance exercise and leave the heavy exercise behind because “it’s a young man’s exercise and too strenuous.” The premise of chair-exercise raises questions about increasing muscle mass.

The first question is simple: Do chair-exercise programs benefit the people who utilize them? Yes. They appear to help people who are older than 60 with flexibility and balance issues. There are dozens of exercises, from the simple such as ankle flexion and extension, to something more rigorous like squats by standing up and sitting down in a chair.

There are two more questions related to chair exercises and the approach the ads take while promoting such programs; I’ll cover that on Saturday. In the meantime, find a solid chair (preferably with arms, but it’s not critical) and do as many squats—meaning standing up and sitting down—as you can, every day, in one set, from now until Saturday.

Finding New Ways

/in /by

Thanks to everyone who wished me a happy birthday by replying to Paula’s Memo or on social media. I appreciate the sentiments and the kind words; it’s great to have you along for the ride as we all try to be healthier.

After a long, drawn-out process, my email has been whitelisted again by the powers that be in that arena. If you’ve missed some Memos in the past couple of months, check your spam folder. They may be there, or you can just visit the website and look through the Memos section.

New Ways

Whether you’re in your 20s, your 70s, or any place in-between, our bodies change over time. The things we used to do with ease, even something as simple as walking, can become challenging.

I heard a quote that went something like this: “I can’t do things the normal way. I have to do things a different way.”

We can relate that to anything we used to do with ease but may now limit us. I’ve noticed a subtle change in my balance—not one that has resulted in falling, but just enough that I notice it. I definitely have noticed a change in my strength. Those are physical attributes.

Our brains change as does just about every system in the body. There may be changes in the digestive system. If there is one thing I’ve learned over the years is that pretty much everyone dislikes any change in their bathroom habits. What was once your normal may not be normal more for you.

That realization is a critical junction. You can begin to limit what you do, or you find a different way to do it. It may require a change in the type of exercise or even beginning to exercise at all. Or maybe a more diverse diet, weight loss, or better dental care. And on and on.

As our bodies change, our normal way of doing things may change. You can decide to shrink your world, or you can decide to do things a different way. It all depends on what you want your world to be.

Lift Five Kilos to Live Better

/in /by

Anybody up for knocking out 25 pushups? How about 10? How about just one? Let’s make it more practical: pick up your largest cast iron frypan or Dutch oven. Or pick up a 10-pound sack of flour or sugar and lift it over your head. Can you do it? Who cares? Maybe you should, and here’s why.

Researchers examined data collected between 2013 and 2020 from the Survey of Health, Ageing, and Retirement in Europe (commonly called SHARE). This includes 16 countries and has over 51,000 participants over the age of 50 who have joined the study. The participants were tracked for over four years. The participants provided medical histories, health habits, and included some physical testing at baseline and then twice afterward including handgrip strength. Key question was, “Can you lift five kilos (11 pounds)?”

After analyzing the data, researchers found that those subjects who could not lift five kilos had higher risks for developing a low quality of life, depression, low handgrip strength, and osteoarthritis. In addition, they were also at risk for rheumatoid arthritis, heart attack, type 2 diabetes, hypertension, Alzheimer’s disease, stroke, or hip fracture. Nothing good on that list for sure.

This was an observational study, so cause and effect cannot be established. But the genius of the study was using objects used in everyday life that weighed about five kilos. That demonstrates that age-related sarcopenia, the loss of muscle, really can impact life, and the risk increases the older that we get. You don’t have to have Hulk-sized muscle, but you still need to maintain a practical amount muscle strength as you get older. Time to hit the weight room or yoga or exercise tubes!

Insiders Call Is Tomorrow

For all those who’ve let me know about their vegetable and fruit intake over the 4th, I’ll send out the log-in information Wednesday morning so you can participate in tomorrow’s Insider call. Main topic is a look at some of the products such as drinks and patches that seem to be highly promoted these days; fact or fiction? You’ll find out tomorrow and find out what being an Insider is like.

Creatine: Does Size Matter?

/in /by

The researchers in Tuesday’s study demonstrated that the use of creatine did not increase muscle size after considering the increase in fluid levels. The major problem is the limited scope of the study: looking only at changes in lean body mass. While the researchers should be given credit for the approach using DEXA, there are several issues with the study.

Age: The researchers used both men and women in the study—no problem if you have enough of each gender. The problem was that they included subjects between 18 and 50 years old; research has shown that muscle loss due to age can begin as early as 40. With only 63 subjects, ideally it would mean 15 men and 15 women in each group. Dividing those few subjects into under 40 and over 40 means as few as six or seven subjects in each group. That’s just not enough subjects to prove their point; it’s sufficient for a pilot study, but not enough to determine health recommendations.

SEM: SEM stands for Standard Error of Measurement. The DEXA scan has limitations in determining the lean body mass with precision. The differences in lean body mass fell within the standard error of the measurement; the measuring tool wasn’t precise enough to measure actual differences.

Strength: Where was the strength data comparing differences in gains between the creatine and experimental group? Looking at lean body mass is looking at a combination of factors, but strength is strength: the amount of weight can you lift in several lifts like the dead lift, the squat, and the bench press. You can’t do such an intensive study and not measure the simplest variable. I’ve emailed the corresponding author, but he’s on a break in Australia. If I get a response, I’ll share it with you.

The Bottom Line

Creatine is a natural substance that may be beneficial for a variety of issues besides muscle growth. I use it every day because I lift to increase strength, but also because it benefits energy levels, skin, muscles, and other organs as well. I think everyone over 40 can probably benefit from taking five grams of creatine monohydrate every day.

Check with your doctor to find out your limitations on exercise intensity and get after it. Weight training should be a part of your regular routine, and creatine is a natural way of making more energy to increase muscular strength.

Use It!

/in /by

Paula, Riley, and I were in South Carolina for the past week visiting our son and his wife; the picture shows some of us collecting shells at Edisto Beach. After getting in and out of a boat, I came face to face with an issue that’s been bothering me for a while: balance. I don’t mean I’ve been falling down a lot; I mean getting the sensation that I’m not as stable as I used to be.

I decided that I was going to hit the road again—walking. I’ve been using the recumbent bike almost exclusively to maintain my fitness. But the lack of movement over uneven surfaces as you’re moving forward (or backward or sideways) causes stabilizer muscles to atrophy quicker than when you were younger.

We also helped cut down a couple of small white oak trees and stacked what will be firewood. Freshly cut wood is heavier than you might expect, and that brought to light the muscle I’ve lost.

Let me summarize it this way. Your body is going to change, without question. The more physical tasks you give up, whether it’s shopping for and carrying groceries, working in the garden, even taking out the garbage, the more physical decline you’ll have. Exercise is important for many reasons, but functional fitness helps you live your life. Use your body, or your world will start to shrink.

If losing muscle is worrying you, download Taking Back Your Muscle and Reclaiming Your Power, the first two parts of the Aging with a Vengeance series; they’re on sale for only $9.95 each. Meanwhile I’m working on the next Aging with a Vengeance presentation; the topic will be memory and learning. If you have any questions about diet, supplements, or products you’ve heard about, let me know and I’ll weave them into the presentation. It doesn’t matter how old you are now—this is about the number one fear that comes with aging: losing what we know. We’re going to attack it with a vengeance!

You’ve Got Another Chance

/in /by

Did you assess your time spent investing in your health as I outlined in Tuesday’s Memo, counting up the time per day, week, or month you spend in the activities that will benefit your long-term health? How did you do? Did you think of more than the short list I provided? Did you come away disappointed with your efforts? I know that I did in some areas.

Life is giving you another chance—in fact, it’s giving you more than one. As long as you draw breath, you can always start. You don’t even have to wait until the new year; pick one thing and begin working on it today. Then, when that change becomes a habit, start on another one. You don’t have to begin everything all at once; in fact, it’s better if you try one change at a time and see how that works before adding more.

If you fail, start again. As Seth Godin said in a recent post, everyone needs more chances. But whether this is the time you actually lose the weight, lower your HbA1c, add that muscle, or whatever is important to your long-term health, taking that next chance is determined by only one thing:

What are you going to do with that chance this time?

It doesn’t matter what you haven’t done—you need to succeed only once at changing a poor health habit into a good one that you will maintain. Take that chance and do something with it this time. Next year, we all could be having completely different conversations. So, really:

How Much Time Did You Invest?

/in /by

As the new year approaches, it’s a good time for reflection. Regardless of your age, taking care of your body should always be a top priority, so let’s assess 2024. Here’s a series of questions—not a complete list by any means, just a place to begin. The overall question is this:

How much time do you spend each day taking care of your body?

How many minutes do you spend on aerobic exercise?

How much time in resistance exercise to maintain or gain muscle?

How much time stretching to maintain flexibility?

How much time massaging your aching muscles?

How much time do you spend cooking foods with natural nutrients?

How much time recording the foods that you eat?

How much time flossing and taking care of your teeth?

How much time caring for your skin?

How much sleep are you getting?

These are not just rhetorical questions. Spend some time thinking about it. Add other questions related to how you take care of your body or issues you’ve been having. Write down the minutes per day you spend in each one of those areas. Do it for the next three days, and you’ll see where you stand now and where you can improve.

You get out of your body what you put into it. You need to think and assess so you can identify what you need to work on in 2025.

This year’s final Insider Conference Call is tomorrow night. The main topic is going to be why research on science should never stop or slow down. This is the time to become an Insider to help you achieve your health goals in 2025. Join by 8 p.m. ET tomorrow night and you’ll be a part of the call.

Sprint Interval Training

/in /by

Keeping with the theme of using interesting training techniques from the last Memos on HIIT training, this next study took it one step further. The objective was to see how fast subjects could get fitter using a sprint interval training program.

I think I need to define some terms here. When we talk about getting fit, there are different types of fitness. There can be tests of strength like lifting the most amount of weight in a bench press. There can be tests of stamina such as how many push-ups a person can do. But when exercise physiologists talk about fitness in the classic sense, they mean how much oxygen your body can use at maximal levels. It’s called max VO2.

To test whether or not someone could become fitter in as little as two weeks and continue to increase their fitness level through the six weeks of a training program, researchers recruited a group of 18 sedentary men with an average age of 23; five subjects dropped out over the course of the study. The reason the researchers chose this particular research topic was because prior research had shown that the initial gain in fitness was not increased further with continued training.

While prior research had used 30 seconds of sprinting with four minutes of easy moving, the researchers chose 15-second intervals on a bike with two minutes of easy pedaling and rest before the next interval. After a physical including an ECG, the subjects were allowed to practice the sprint/rest cycle twice before the actual program began. There were three cycles of workouts that went like this: they began with the max VO2 test to determine the resistance in the sprints. Then in succeeding workouts scheduled every two days, the number of intervals per session began at 10 sprints, then two sessions at 12 repetitions, a session of 14 sprints, and finishing with eight sprints. Then the cycle repeated.

What did they find? Were they fitter? You bet they were, but I’ll save the details for Saturday.

Insiders, I’ve changed the conference call date from June 12 to June 19. Being an Insider allows you to get details that would be too time consuming in Memos. For example, I’m researching omega-3 supplementation in light of all the recent studies questioning its use. I want to find out what’s going on, and I’ll talk about it a week from Wednesday.

Anticipate Change

/in /by

Adapt. Innovate. Improvise. Overcome. That’s a group of words I put together years ago about how to respond when faced with challenges. The approach works in the present. When it comes to changes in health that are associated with aging, we don’t know exactly what they will be. Therefore, we must anticipate what might happen. I’ll give you some examples to consider.

Things to Consider

What we value the most is our independence. Still, your body will change; you may see changes in strength, balance, vision, joint health, mental acuity, or fitness. That doesn’t count any new conditions or diseases.

Should you continue to drive? That would be about the last thing I’d want to give up, but glaucoma may have a say in it. And reaction time declines with age. Which abilities can you work to improve? What alternatives can you prepare for?

Having a two-story home with a basement is great. Will you always have the capacity to go up and down the stairs to do laundry or to retrieve stored items? Would moving to a ranch home with everything on one level be a better choice?

Going up and down a ladder to clean gutters could become a problem. Heck, getting the extension ladder out of the garage could be an issue. Plan for gutter covers. That’s one change I made when I could do it myself. I could still clean them, but now I don’t need to.

What about cooking? Cleaning? Snow shoveling? Lawn maintenance? Anticipate what you really want to do yourself and what you’re willing to let someone else do.

Am I Just Giving Up?

Understand this. This is not about giving up; this is making a conscious decision to adapt to new circumstances. Your body is different from what it used to be.  Doesn’t matter whether you’re 40 now, or 50 or 60 or over 70—your body doesn’t have the same capabilities, and it will differ even more in 10, 20, or 50 years. You must adapt to it, or you’re going to end up frustrated all the time. Because believe me, you’re not going to be able to do everything that you used to do in the same way.

Anticipate the changes that may occur. If you start preparing for that now while you may not need it, you’ll be ready for it if you do. The choices of what you will and will not be able to do are going to be different for every person, but we can probably all stand to simplify our lives.

Anticipate. Innovate. Improvise. Adapt. And you will overcome.

The Bottom Line

There’s a new year on the horizon, so now is a good time to think about the changes I’ve talked about. Most of us are not good at anticipating what our bodies will do, but I can virtually guarantee one thing: the less body mass you have, the easier it will be to do everything. What you can do starting now is methodically get to a normal body weight for your height, stay active, and work on your strength and stamina. I’ll continue to provide you with research-based actions you can take to age with a vengeance. Nobody ever said you have to go quietly.
