I fractured my ankle at 7 years old.
Spent the next 20 years dealing with knee pain that nobody could explain. Doctors looked at my knee. Therapists worked on my knee. Nobody looked below it.

The tibialis anterior sits directly below the knee joint. It’s the first muscle to absorb force every time your foot hits the ground.

When it’s weak, that force travels straight into the knee.

Tib raises changed everything for me. Not a stretch. Not a foam roller. A muscle that was never trained finally being trained.

This is the first line of defense against knee pain and almost nobody talks about it.

3 sets of 10-15 reps. Add a kettlebell across the foot as you get stronger. Do this daily.

Build below. Protect above.

That’s Basketball Biology 🙏🧬 David Mariani

If you have knee pain, this is the muscle nobody told you to train.

The soleus. Most people know it as a calf muscle. What they don’t know is it’s one of the most important muscles for knee health.

The bent knee calf raise isometrically loads the quad tendon while concentrically and eccentrically strengthening the soleus at the same time.

That combination is everything for knee stability and pain reduction.

I fractured my ankle at 7. Spent almost 30 with knee issues after that. Osgood slattters, patellar tendinitis, torn mcl on both knees, torn meniscus on both knees and no cartilage by 18.

It wasn’t until I understood the full chain - tibialis, soleus, and how they load the knee - that everything changed.

3 sets of 15-20 reps. Slow and controlled.

Knee stays bent the entire time.

If you have ankle pain, weak ankles, or keep rolling the same ankle - this is why.

I fractured my ankle at 7 years old. Spent the next decade spraining it over and over.

Nobody ever told me about this muscle.

The moment I started training it, the injuries stopped completely.

The tibialis anterior and soleus are the two most undertrained muscles in the lower leg
- and the ones I’ve built my entire methodology around.

The tibialis anterior controls how your foot lands and how your ankle absorbs force.

The soleus manages the load that travels up through your knee and hip. When both are weak, everything above compensates - and that’s when injuries happen.

Tib raises fix this. Start bodyweight, progress to a kettlebell across the foot like shown. Slow and controlled - full range beats heavy load every time.

3 sets of 10-15 reps. Do this daily.

The hip joint has no direct blood supply.

Every doctor knows this.

Almost none of them tell you what it means.

It means your hip feeds through synovial fluid.

Produced and circulated by movement and compression.

No movement. No compression.

No fresh, nutrient-rich fluid

That’s why hip pain gets worse with rest.

That’s why surgery often fails long term.

That’s why the system keeps you coming back.

The truth existed before the clinical trials.

Before the studies. Before the papers.

Movement is medicine.

Compression is nutrition.

I’ve had more hip and joint injuries than most people will have in a lifetime.

I’m 38. Pain free. More athletic than ever.

This is what I found.

And I’m giving it away.biology

Billions spent on insoles

Pain still there

Because overpronation isn't a foot problem

It's a muscle problem

The soleus controls your arch.

Your ankle stability

Your knee alignment

Your entire lower chain

Insoles manage the symptom

This fixes the source

What do orthotics cost?

What does physical therapy cost?

What does surgery cost?

Now ask the real question -

What is access to rare, outcome-producing intelligence worth?

I've been broken since I was 7

The system had no answers

This muscle did

And I'm giving it away.
