There seems to be this idea that once you hit a certain age, getting weaker, gaining body fat and watching your physique slowly deteriorate is simply part of life.
I don’t buy into that.
Does your body change as you get older? Absolutely.
Recovery can take longer. Injuries can become more common. You probably can’t get away with some of the stupid things you did in the gym when you were 20.
But getting older also gives you something incredibly valuable:
Experience.
And if you actually use that experience, I believe your approach to fitness should become better with age — not worse.
I’m 40 now, and there are plenty of things I do differently than I did when I was 20.
I don’t care about impressing anyone with how much weight I can lift. I don’t chase one-rep maxes. I don’t believe every workout needs to leave me destroyed. And I certainly don’t subscribe to the idea that pain automatically means progress.
What I care about is building and maintaining muscle, staying lean, training consistently, keeping my body healthy and being able to continue doing this for decades.
That’s the difference between simply getting older and actually learning from getting older.
1. You Should Know Your Body Better Now
When you’re young, a lot of fitness is trial and error.
You try different workouts. Different diets. Different exercises. Different training splits.
Some things work. Some don’t.
But after you’ve been training for years, you should start paying attention to those lessons.
Which exercises actually produce results for you?
Which movements consistently bother your joints?
How much training volume can you recover from?
What foods make you feel and perform your best?
How much sleep do you need?
At some point, you should stop constantly searching for the newest fitness trend and start using the information your own body has been giving you for years.
Experience should make your training more individualized.
2. Training Smarter Should Replace Training Recklessly
I trained differently when I was younger.
Like a lot of people, there was more ego involved. More emphasis on how much weight was on the bar. More willingness to push through things that probably should have been addressed instead.
These days, my priorities are different.
I’m still a high-volume trainer. I still train hard. I still believe you need to challenge yourself if you want to build and maintain muscle.
But I also want to be able to train tomorrow.
And next year.
And hopefully 20 years from now.
There’s absolutely nothing impressive about destroying your shoulder trying to bench a weight you had no business attempting just so you can say you lifted it.
Train hard enough to create results. Train smart enough to keep creating them.
That’s a lesson I appreciate much more at 40 than I did at 20.
3. Your Nutrition Should Improve With Age
This is another area where getting older can actually work in your favour.
Most of us weren’t exactly making perfect nutritional decisions when we were teenagers or in our early 20s.
But eventually, you learn.
You learn how your body responds to certain foods.
You learn the importance of protein.
You learn how much your portions matter.
You learn that eating well consistently produces dramatically better results than bouncing between extreme diets.
And hopefully, you learn that you don’t need to turn every weekend into a nutritional disaster simply because you were disciplined Monday through Friday.
Your metabolism may change as you get older, but your knowledge should change too.
Use it.
4. Consistency Becomes More Important Than Intensity
One of the biggest mistakes I see people make is thinking fitness requires these massive bursts of motivation.
They decide they’re going to change their life.
They train six days in a row.
They completely overhaul their diet.
They push themselves as hard as possible.
And three weeks later, they’re done.
I’d rather see someone put together 300 good workouts over the course of a year than 20 unbelievable workouts followed by months of doing nothing.
You don’t need every workout to be legendary.
Some days you’ll feel incredible.
Some days you’ll simply get the work done.
Both count.
The older I get, the more I believe that long-term consistency is one of the biggest advantages you can possibly have.
5. Don’t Let Your Age Become Your Excuse
This is probably the biggest one.
There is a difference between respecting your age and surrendering to it.
Respecting your age means warming up properly.
It means paying attention to recovery.
It means not ignoring injuries.
It means choosing exercises intelligently.
It means understanding that what worked for you at 20 might need to be adjusted at 40, 50 or 60.
Surrendering to your age is different.
That’s when every extra pound becomes, “Well, I’m getting older.”
Every missed workout becomes, “I just don’t have the energy anymore.”
Every physical limitation becomes another reason to stop trying.
I don’t think that’s the answer.
Your training might need to change.
Your nutrition might need to change.
Your expectations might even need to change.
But that doesn’t mean you stop.
Your Best Years Don’t Have to Be Behind You
Fitness shouldn’t be about desperately trying to look exactly like you did when you were 20.
It’s about becoming the strongest, healthiest and most capable version of yourself at the age you are today.
And then continuing to work on that version tomorrow.
At 40, I train differently than I did at 20.
I think differently about fitness.
I understand my body better.
I care far more about longevity.
And I’ve learned that being able to consistently show up year after year is much more valuable than proving how tough I am during one workout.
So yes, getting older changes things.
But change doesn’t automatically mean decline.
If you’ve accumulated years of experience, learned from your mistakes and become more disciplined with your training and nutrition, there’s no reason you can’t continue improving.
Respect your body.
Train intelligently.
Eat properly.
Stay consistent.
And don’t use the number on your birth certificate as permission to stop taking care of yourself.
Getting older is mandatory.
Getting out of shape isn’t.
Yours in Good Health,
