Why Fit Athletes Keep Getting Hurt

Last week I was talking with an athlete who couldn't figure it out.

They were training six days a week.

The workouts were going well.

Fitness was improving.

But every few weeks, something else started hurting.

Sound familiar?

After more than 16 years of coaching endurance athletes, I've learned something.

Getting fitter doesn't automatically make you more durable.

In fact, sometimes it does the opposite.

Most endurance training happens in a straight line.

You swim forward.

You ride forward.

You run forward.

Day after day, your body becomes really good at repeating the same movement.

But life doesn't happen in straight lines.

It's twisting to grab the water bottle you dropped.

It's stepping off a curb.

It's slipping on wet pavement wearing cycling shoes.

It's getting out of bed after a hard weekend of training.

That's when weaknesses show up.

I see it all the time.

An athlete is aerobically fit.

Mentally tough.

Training consistently.

Then one awkward movement tweaks a back.

A speed workout turns into shin splints.

One bad step becomes hip pain that ruins an entire race build.

Fitness vs. Durability

The problem isn't that they weren't fit enough.

It's that they built fitness faster than they built durability.

There's a difference.

Fitness is your ability to produce performance.

Durability is your body's ability to keep producing it.

Try This Durability Test

One of my favorite ways to demonstrate this is incredibly simple.

Sit down on the floor.

Now stand back up...

Without using your hands.

If that's harder than you expected, your durability may not be keeping up with your fitness.

I recorded a quick 7-second demonstration here:

Build Durability First

The solution isn't more mileage.

It isn't another hard workout.

It's teaching your body to move well in more than one direction.

Improving mobility.

Building strength.

Learning better movement.

Fixing weak links before they become injuries.

That's why durability is the foundation of everything I coach.

Because the athletes who improve the most usually aren't the ones who train the hardest.

They're the ones who stay healthy enough to keep training.

If that sounds like something you need, I'd love to help.

Key Takeaways

• Getting fitter doesn't automatically make you more durable.

• The athletes who improve the most are usually the ones who stay healthy enough to train consistently.

• Train to prevent the strain—not just improve your fitness..

As always...

Start where you are. Use what you have. Do what you can.
