The myths surrounding fitness and health are quietly sabotaging your ability to age well, maintain independence, and enjoy quality of life as you get older. This article reveals the truth about what it really means to be “fit to live” by exposing common misconceptions about muscle confusion, the “no pain, no gain” mentality, and how your body’s energy systems actually work for optimal results.
Understanding these fundamentals will help you build sustainable movement habits that protect against sarcopenia (age-related muscle loss) while avoiding the overtraining mistakes that lead to injury and burnout.
In my recent video discussion with fitness expert David Hesterley, we break down these critical concepts in detail.
Why Movement Naturally Becomes Exercise as We Age
When you think about fitness and you think about all the things that we’re told, there’s so many videos we see about people who are working out and strength training and doing fascinating cardio things, but what is it really all about? The foundation starts as a child and a child has so much energy.
I was watching a couple little ones the other day and they were just running around playing basketball and they weren’t thinking about exercise. They were just playing and they were just moving and having a ball, running around, throwing a basketball. Games just turned into movement.
No one had to teach them to do that. They were just moving naturally. But as we age with lifestyle and with culture and with the demands of job and career and those kind of things, relationships, we become sedentary. Different injuries happen and that causes us to move different or move less.
Responsibilities of office jobs or driving a lot keeps you from moving and then all of a sudden it becomes a chore and we call it exercise when we should have just kept moving the whole time like we did when we were children. So a lot of times people get great results doing very basic movements, going back to those foundational things.
How Technology Creates Comfort but Reduces Movement
It’s the blessing and curse of technology, right? We have so much access to be able to do things with technology, but we still have to move our bodies. And so we have to make sure that we don’t allow technology to keep us from moving.
At that time, you know, 3,000 years ago, 4,000 years ago, people didn’t have technology to keep them from doing things. They had to physically do things. And now that’s why you see there’s great benefit and it’s not even exercise is great, but even just staying active has so much health benefit throughout your life.
The person you ever talk to somebody and they’re just always doing this kind of stuff, you know, as they’re talking, they’re talking with their hands, they’re making these great gestures, they’re actually burning so many more calories than the person that’s just sitting and just talking like this.
Moving consistently throughout the day is actually more beneficial than someone that’s spending an hour in the gym strength training three times a week and getting their cardio in four times a week. Someone that’s just actively moving throughout the day as a way of life – that’s the best exercise.
The Myth of “Muscle Confusion”
Muscle confusion became a marketing fitness marketing term, but I like to think of, you know, if my muscles were confused, how could I walk? I picture walking with confusion, you know, you’d look real clumsy. I like to think of muscle organization.
To get increase in fitness, you have to place specific demands on your body and those demands have to get more challenging over time. There’s two ways to increase intensity in a workout. You increase intensity by increasing the load or you increase intensity by increasing the reps.
Reps are king. There was a real famous trainer Charles Poliquin that I got that from because if you really think about any movement you’re doing in terms of strength training, it’s dictated by reps. If I tell you I need you to do 12 repetitions of this movement, you’re automatically thinking it’s going to be a lighter amount of weight than what I would do for five.
Understanding Your Body’s Energy Systems
You have different energy systems in your body. You have the creatine phosphate energy system. This energy system is the type of energy that’s going to last for 20 seconds or less. It’s the type of energy that you would use to lift a really heavy weight.
Then you have the aerobic or oxidative energy system that has to be trained. That’s using oxygen for fuel. The creatine phosphate system uses ATP, adenosine triphosphate for fuel. It’s stored in the muscles. It’s ready to go for instant movement.
And then there’s glycolytic training, which is kind of in the middle of those two. It’s using glycogen for fuel. It’s like a sugar that your body has that can burn hot, but at a certain point you’re going to run out of that and going to have to transfer to oxidative or aerobic oxygen fuel source of training.
Debunking “No Pain, No Gain”
No pain, no gain – that’s a big one. You do have to push. There will be sometimes a certain amount of pain involved, but there’s still great benefits to just moving. The problem with the no pain, no gain is people have pushed to the point of injury.
The best thing to do is train to a place where you’re challenging yourself. There’s actually a buffer zone. If you look at like your speedometer or even your RPMs on your car, there’s this sweet spot where you’re at the three to four maybe RPMs when you’re accelerating, but then you can really step on the gas and be in that red line spot.
You don’t want to always train in that red line spot. You want to touch that red line from time to time, but there’s a buffer zone. There’s only so much you can stay there without increasing your risk for injury exponentially.
Learning from Professional Athletes
What’s the big deal in the NBA right now? Load management. These athletes are saying, “Look, my body is worth millions of dollars a year. It makes more sense for me to sit a game every fourth game or something because this is my way to make money.”
World record powerlifters, and they’re mostly enhanced, and even them at their enhanced state, they’ll only do a max lift every third or fourth week. So they train for three or four weeks to get to that one day where I’m going to be at my max.
Every day can’t be game day. There’s some days where your body maybe those workouts shouldn’t have been an intense workout. Maybe those days it should just be skill focused.
The Truth About Training to Failure
I like to say train to muscle failure, not mechanical failure. Muscle failure is when you get to that rep where all of a sudden the bar speed slows way down. The first few reps you were just jamming through them, but then you get to that spot where as you press up – that’s muscle failure.
Now you can rack the weight. You’ve now stimulated your muscles sufficiently for some progress. Don’t do another rep at that point because you increase your risk for injury.
One set to failure is going to give you 90% of results as five sets would give you. The gains or the law of depreciation kicks in on your second set, your third set – there’s less benefit to each additional set you do.
Focus on Functional Movements
Most good strength training programs will be built around movements that focus on compound joint movements – pull-ups, push-ups, squats, bench press, deadlifts, lunges. These are things that are multi-joint.
