ACL tears aren't just knee problems. Non-contact tears often stem from elsewhere: foot mechanics, hip rotation, even thoracic spine issues. Fixing the root cause is key to restoring function and preventing re-injury.

We discuss this and much more with the legend Gary Gray on this week's podcast.

You don’t have a marketing problem.

You have a retention problem.

You hired a marketing agency.
You spent thousands on ads.
You got 20, 30, maybe 50 new members through the door.

Congratulations.

But here’s the question nobody wants to ask:

How many of them will still be there 6 months from now?

Because getting people through the door is easy.

Getting them to stay is the real business.

Your ads can be incredible.
Your social media can look amazing.
Your offer can be irresistible.

But if the actual experience inside your gym is mediocre…

You’re just marketing a bad product.

Imagine opening a pizza joint.

You spend thousands on marketing.
Your ads look incredible.
You hype up your food.
You get people through the door.

Then they take their first bite…

And the pizza tastes like three-day-old Domino’s.

Do you think they’re coming back?

Of course not.

Yet this is what gym owners do ALL THE TIME.

They focus on getting more members while ignoring the reason members leave.

And that’s a problem.

Because the most successful and profitable gyms don’t need 30 new members every month.

They keep the members they already have.

Retention beats marketing 99% of the time.

So ask yourself:

Do you really need more members?

Or do you need to create a better experience for the ones already walking through your doors?

That’s where systems come in.

Systems for your intake process.
Systems for your evaluations.
Systems for your programming.
Systems for your coaching and cueing.
Systems for educating and developing your coaches.

Because great gyms don’t rely on one great coach, one great program, or one great personality.

They build systems that consistently deliver a great experience.

Stop trying to fix a retention problem with more marketing.

Fix the product.
Fix the experience.
Build the systems.

If this sounds all too familiar, shoot us a message.

We can help.

Stop wasting your time on "Remedial Feel the Burn" core training. Burning your abs doesn't build muscle or function or create 6-pack abs. Train your core by following the principles of exercise science.

When we talk about training the "core" we need to define what that actualluy means, which is easier said than done, because is core isn't just your abs.

Before you scream at young athletes, understand their stress. Ask them why they aren't meeting expectations. They might not have missed your workout due to laziness or lack of commitment. They may have a sick parent, take care of younger siblings or have to work part-time to support family. Acknowledge their burdens before you place blame.

This week Eric and Mike discuss Strength and Conditioning at the High School level.
