Why You Feel Stiffer After 50—and What to Do About It

By Bobby Kelly | Results Only Fitness | Phoenix, Arizona

After 35 years on the gym floor, I’ve heard this sentence thousands of times:

“I’m just getting old.”

Usually I hear it right after someone struggles to get off the floor, reach overhead, squat comfortably, or turn around to look behind them.

And I usually have the same response.

Maybe.

But let’s not give age credit for everything.

If you’ve spent the last 20 years sitting at a desk, driving everywhere, staring at screens and gradually moving your body through fewer and fewer positions, some of what you’re feeling isn’t simply age.

Your body gets really good at doing what you repeatedly ask it to do.

And it also gets really good at NOT doing what you stop asking it to do.

Mobility and Flexibility Aren’t the Same Thing

People often assume being mobile means being able to stretch farther.

Not exactly.

Flexibility is about range of motion.

Mobility is being able to actually control your body through that range of motion.

That’s important after 50 because I don’t just want you to be able to touch your toes.

I want you strong enough to use your body.

Get off the floor.

Reach overhead.

Carry groceries.

Play with your grandkids.

Travel.

Golf.

Hike.

Keep doing whatever makes your life your life.

That’s the goal.

Stop Treating Mobility Like Another Workout

Here’s where busy people make this harder than necessary.

They think:

“I already have to exercise. Now you’re telling me I need another 45-minute mobility workout?”

No.

Good strength training should include mobility.

At Results Only Fitness, that might mean moving through different ranges of motion during a warm-up, working side-to-side instead of always straight ahead, using single-leg exercises, or getting stronger through ranges you haven’t used consistently.

You don’t necessarily need another workout. You need a better-designed workout.

Ten Minutes Done Regularly Beats an Hour You Never Do

This may be the least sexy fitness advice I’ve ever given.

Do a little bit consistently.

Five minutes today.

Ten minutes tomorrow.

Move during your workday.

Get out of your chair.

Use your joints.

Then come into the gym and strengthen those movements.

Your body responds to what you repeatedly ask of it.

One heroic stretching session on Sunday doesn’t erase six days of sitting.

Strength Is Part of Mobility

This is the part I think gets missed.

If you can get into a position but don’t have enough strength and control to use that position, how useful is it?

That’s one reason strength training becomes so important as we age.

We aren’t simply trying to make muscles bigger.

We’re building a body that can still DO things.

I want you stronger at 60 than you were at 50.

I want you confident getting off the floor.

I want you traveling without worrying about whether you can carry your suitcase.

I want you saying yes to things instead of wondering whether your body can handle them.

Don’t Blame Your Birth Certificate

Aging is real.

Our bodies change.

I’m not going to sell you some ridiculous story that 60 is exactly the same as 25.

It isn’t.

But there is a huge difference between aging and simply becoming less active.

Don’t surrender something your body may still be perfectly capable of doing because you’ve decided, “I’m too old for that.”

Give your body a reason to keep moving.

Give it resistance.

Give it different ranges of motion.

Give it consistency.

And get some coaching when you don’t know what to do.

The Bottom Line

After 35 years of coaching, I’ve become much less interested in helping people simply “work out.”

I want to help people stay capable.

Because the real goal of fitness after 50 isn’t winning your workout.

It’s being able to keep saying yes to your life.

At Results Only Fitness in Central Phoenix, we help adults over 40 build strength, improve mobility, increase energy, and create sustainable habits that fit real life.
