Correlation or causation?

One of the best parts of my job is that I get to work with some incredibly bright people who ask great questions.

I got one this week.

I had mentioned that grip strength and leg strength are two of the biggest indicators associated with “longevity.”

Longevity being the hot word these days that basically means:

How long do you get to keep being YOU?

And one of my clients immediately asked:

“Would you say that’s correlation or causation?”

Great question.

And the most accurate answer is…

We don’t completely know.

We have really good evidence that people with better grip strength and lower-body strength and function tend to have better outcomes as they age.

But that doesn’t necessarily mean squeezing a gripper until you have the hands of a gorilla is going to make you live to 100.

Grip strength may also be telling us something about the person attached to the grip.

Are they active?

Do they have muscle?

Are they generally healthy?

Can they still DO things?

Success leaves clues.

But I think we have to be careful not to turn the clue into the goal.

Because if stronger is associated with better outcomes…

It doesn’t automatically follow that infinitely stronger is infinitely better.

Money works the same way.

Having enough money can solve a LOT of problems.

But eventually…

More money probably doesn’t improve your life much if getting it requires giving up your family, friends, hobbies and everything else you actually enjoy.

Strength is a little like that.

I want you strong enough to pick things up.

Get off the floor.

Carry your groceries.

Play pickleball.

Travel.

Garden.

Play with your grandkids.

Keep doing the things that make you YOU.

After that?

We can certainly keep getting stronger.

But we’re not trying to win strength training.

We’re using strength training to help you win everything else.

So How Strong Is Strong Enough After 50?

Here’s the problem with most fitness advice:

It tells you to do more.

More weight. More workouts. More exercises. More suffering.

But after 50, the smarter question isn’t: “How much can I possibly do?”

It’s: “What is the right amount to keep me strong, capable and doing the things I actually care about?”

That’s exactly what I help people figure out inside my 12-Week Get Stronger and Live Longer Program.

I handle the exercises, weights, repetitions and progression. You show up, train intelligently, and get stronger without turning your workouts into another full-time job.

Not Ready for Coaching Yet?

Fair enough.

Keep reading. The more you understand what actually matters after 50, the less likely you are to waste time doing things that don’t.
