44”… IN NIKE SLIDES. 🩴😳

Julian Whitfield just touched 11’4½” on the Vertec for a 44-inch max vertical…

…wearing Nike slides.

Imagine what happens when he laces up. 👀

The best athletes don’t just hope to become more explosive—they train for it.

The work speaks for itself.

How high do you think he gets next week in athletic shoes? Drop your guess below. ⬇️

🥱 …

Everyone wants to know the secret to dunking… 😏🏀

Years of training.
Countless hours in the gym.
A commitment to excellence.

…and a strategically placed staircase of boxes out of frame. 😂

Work smarter, not harder.

🚨 “Knees caving in causes injuries.”

But what if it’s not that simple?

For years, dynamic knee valgus (the inward movement of the knee during jumping, landing, and cutting) has been treated as the villain behind ACL tears and knee injuries. Yet emerging research suggests the relationship may be far more complex.

Athletes don’t compete in perfect laboratory conditions. They move in chaotic, unpredictable environments where adaptation, strength, coordination, and load tolerance matter just as much as movement mechanics.

So instead of asking:
❌ “Does the knee move inward?”

Maybe we should be asking:
✅ How much load can the athlete tolerate?
✅ Can they control that movement?
✅ Are they strong enough to handle the demands of their sport?

This isn’t about saying dynamic knee valgus is good or bad.

It’s about thinking critically, questioning assumptions, and recognizing that human movement is rarely black and white.

I’d love to hear your thoughts:

Do you think dynamic knee valgus has been overemphasized in sports medicine and performance training?

Work speaks 🗣️

Most athletes don’t have a performance problem… they have a training problem.

If your athlete wants to:
✔ Jump higher
✔ Move faster
✔ Stay healthy all season

They need the right system—not more random workouts.

Train with pwd by The Jump Doctor™️

For years, parents have been told:
“Don’t let your athlete’s knees go over their toes.”

Sounds protective… right?

But that advice comes from outdated research that only looked at knee stress in isolation—not how the entire body actually moves.

Here’s what we now understand:

When the knees travel forward during a squat, yes—there is increased load on the knee joint.
But that’s not a bad thing… that’s how the body builds strength and resilience.

👉 When you force the knees to stay back, you don’t eliminate stress—you shift it.
And where does it go?

➡️ The hips
➡️ The lower back

In fact, modern biomechanical research shows that restricting natural knee movement can dramatically increase stress on other joints.

Now think about your athlete in real life:

Running.
Jumping.
Landing.
Walking up stairs.

Their knees go over their toes every single time.

So the goal isn’t to avoid that position…
It’s to prepare them for it.

Because the athletes who get hurt aren’t the ones who use these positions—
They’re the ones who aren’t strong enough in them.

Train movement.
Build capacity.
Stop fearing normal human mechanics.

That’s how you actually protect your athlete.

❌Stop calling it tendonitis.
That mindset is why athletes stay stuck.
⠀
Most knee pain isn’t inflammation—it’s capacity failure.
⠀
And not all “jumper’s knee” is even the same injury.

🔑If you want to fix it… you have to understand it first.

Jumper’s knee is one of the MOST misunderstood injuries in sports.

And most athletes are doing the exact things that keep it around longer.

So I’m breaking it all down—step by step.
