Conventional Wisdom

Osteoarthritis is a joint problem. But the common non -surgical approach for knee pain from osteoarthritis targets muscle strength.

Most knee arthritis exercise programs are focused on increasing muscle strength because the belief is that stronger muscles will protect the joint and relieve pain.

There's no doubt that having stronger leg muscles helps knee pain.

But there's a problem with trying to strengthen the muscles around your aching knee and you may have run into it.

To strengthen your leg muscles, you have to exercise hard enough that you can feel the muscles tiring out or fatiguing.

It's usually something like 3 sets of 10 -15 repetitions of the exercise. Maybe your muscles get tired, but usually not.

As you push the muscles trying to reach fatigue, your knee starts to ache or it swells or just generally feels bad. Maybe that happens right away or maybe it shows up a day or two later. Either way, you don't make much progress.

If you don't push the muscles, then they just don't get any stronger. If your muscles don't get stronger, they can't help protect the joint.

But the force required to fatigue the muscles is greater than what your knee joint can withstand.

So, what do you do?

The Answer

Strengthening the leg muscles is important but not at the expense of your joint.

The good news is there's a way to boost the strength of your joint and leg muscles without making your knee feel bad.

The concept supporting this idea is based on the science of mechanobiology - how mechanical forces generated within or imposed upon living tissues affect the physiology and structure of that tissue.

Although many in the medical word believe you can't do anything about a weak or injured joint, I debunk this thinking in my book in detail. It's not just my opinion. It's from a large number of scientific studies that support the idea that joints respond to mechanical force but it's how the force is applied and used that makes the difference.

In a nutshell, achy, stiff, sore joints need to be nudged to to get stronger, not pushed. You push muscles. You stress muscles hard and they respond quickly. Joints, you nudge carefully, persistently. And the result is that at a certain point, you can start pushing the muscles because the joint can take it.

You work from the inside - out. Using specific exercises that target the joint tissues and with the right resistance, repetitions, duration, frequency, you nourish the joint, boost the lubricating fluid in the joint, and build the tissue strength.

We lay all of this out in the book and walk you through the process step-by-step.

Who is this book for?

If you have:

  1. A diagnosis of either knee osteoarthritis or chondromalacia patella. If you know you have patellar tendonitis, meniscus tear, ligament injury, a subluxing patella, or a condition other than OA or CP, the solutions for these conditions are different than what I present in this book.
  2. No more than mild to moderate wear or loss of the joint cartilage (Stages 1 - 3). Severe loss of joint cartilage - bone on bone - is a much more difficult problem to resolve and sometimes requires an invasive or surgical procedure.
  3. Intermittent knee pain. If you have constant knee pain, knee pain at rest, pain that doesn’t improve or go away, you should see a physician to determine the nature and cause of your pain.
  4. A strong desire to be active with a clear objective. This is important because you must have a long term goal beyond, “I just don’t want to hurt” in order to fully upgrade your knee.
  5. A desire to learn and apply new material. Much of what I present in this book will be new to you. In order to get the full benefit of the material, you must want to learn and be comfortable applying what you learn independently.

Joints Are Not Muscles

Weak joints need to be nudged to get stronger; not pushed.

Robert is an energetic, trim, attorney in his 40’s. He goes to Bikram Yoga several times a week for his “fitness” routine (Bikram Yoga is performed in a very warm environment). Fitness is critical to him; it’s part of his lifestyle. He likes the way Bikram Yoga makes him feel and he thinks it helps him keep his weight under control.

When I asked him if he ever did any other kind of exercise he said, “Oh, yeah, I used to work with a trainer at a gym but I just found that I hurt more and more after the sessions. I mean, it kept me lean and everything, but my body hurt too much.” In Robert’s case, he found another way to exercise that was kinder and gentler on his joints but not kind and gentle enough. He said that he still hurt; just not as much or as often.

To work through a joint weakness, you first get rid of everything you know to do for muscles including how hard you work, how fast, and how long.

Joints like things to be easy. Muscles like things to be tough.

Joints change slowly. Muscles change fast.

Joints need a lot of motion. Muscles need a lot less.

The kind of exercise you do to strengthen muscles is way too hard for a weak joint. In fact, weak joints are often the reason people either don’t exercise or eventually quit. They hurt too much; too often.

Joints need to be nudged into health; not pushed.

Joints are not muscles.
