If I wanted to push you or an object, a heavy door perhaps at the university or at a shopping mall, say I could bench press 300 pounds. Well, I can't anymore, but say I could. The bench press muscle is the pec major. Let's look at the architecture of the pec major. The pec major crosses the shoulder joint, distal to the shoulder joint, to where it connects on the upper arm bone, the humerus.

The muscle contracts and creates the desired push. But proximal, it connects to my rib cage. Look what it does. It collapses my torso into my shoulder, which is an energy leak. That is anti-push. But if I can use core control and core stiffness and lock down proximally, 100% of that muscle activity now goes distally to the athleticism.

So you may have heard the expression, a stronger core makes you stronger throughout your body. Well, how does that work? I've just explained to you that when you create proximal control and stiffness, it directs the athleticism distally. If you want to wiggle your finger quickly, you had to stiffen your wrist. If you want to wiggle your arm quickly, you had to stiffen your upper arm, etc.

So the mother of all proximal stability is your core. In exactly the same way, a heavy equipment operator using a backhoe, the first thing they do is they put down the stabilizers, which are posts that go into the ground and lift the tires off the ground to stabilize the tractor so that now the arm can be the athlete pulling earth. Failure to stabilize, you're just pulling the tractor around.

So core stability is essential for ability and performance. It's... arresting all little micro movements. We're all shrinking. You will notice this probably over the next decade. The disc height is now shrinking and there's going to be a little bit more micro movement in the discs.

Yes. It will increase disc height for 15 minutes. and then gravity and the hydrostatic pressures will cause the fluid flow. And the fluid flow, there's a little bit through laterally through the disc, but most of it comes through the end plates. So from the vertebral body, into the nucleus of the disc, and you can draw fluid in under tension.

But the hydrostatic pressure overrides the osmotic pressure in gravity, and then the discs lose all the fluid. So it's a 15-minute effect.

I haven't seen any evidence of PRP doing so. Mm-hmm. Now, I didn't condemn PRP throughout the body. I swear by it for stubborn muscle tears in one example. Ball and socket articular joints. There's no question. Not all the time, but it can make a measurable difference, but not injected into the disc. So I just need to give a little bit of a context to this now.
