How to Fix Knee Pain

If you have ever suffered from any type of knee pain, stiffness, clicking or weakness, The Knee Fix is for you. In this program, you’ll get our expert combo of physical therapy and strength training plans to improve joint stability and leg strength, along with identifying and fixing the hidden dysfunctions that are the source of your specific knee issues.

Why The Knee Fix Works

No shot, pill, adjustment, or massage can replace the success, health, and longevity given by The Knee Fix. Other treatments withhold the keys to success and miss the root cause of your dysfunction.


Medicine and drugs only mask pain.

Chiropractic Care

Chiropractic care temporarily adjusts your pain response.

Physical Therapy

Physical therapy often misses the root cause.


Pay high costs for a low chance of fixing the cause.

In simple terms, only by fixing your movement will you fix your knee.

Obviously, fixing movement is not that simple. Doing so requires a specialized doctor, a strength and conditioning coach, a breathing specialist, a massage therapist, a personal motivator, and a personal trainer – and they all need to work together. So we got them to do just that: The Knee Fix is the result.

I’m one week into this program and the pain is gone! I can’t wait to see what else happens. Not getting ahead of myself, but I love the relief. Finally!

My baseline pain has really decreased here by week 6. Oh my God, this is what it’s like not to have to be so constantly and intensely nagged by pain!

Thank you, team! I’ve gained so much confidence in the past 3 months it’s unreal. I didn’t think I’d be picking up a weight for a year after my injury.

The Knee Fix FAQs

How am I billed?

You will be billed immediately upon purchase, as well as monthly after that for as long as you remain a Member.

Describe the money back guarantee.

If you are unsatisfied for any reason within the first 14 days, just contact us and let us know that you would like a refund. We will grant that request and remove your access to the program.

If I have a question or need technical support, what do I do?

Ask away! Think of us as your coach and physical therapist. For health, fitness, nutrition or mindset questions, join an office hours session! We monitor our private member Facebook group and our technical support email and phone 8am-5pm, Monday-Friday (PST).

Is the program mobile-friendly?

Our platform is optimized for any modern device. You can use the program on your smartphone, tablet, or computer.

What if I am unsure how to do an exercise?

Every exercise has written and video instruction. Read and listen carefully to the cues you are given for each exercise or movement, as there’s a ton of knowledge distilled into that guidance. You can also contact us for more help.

Do I need a gym membership or can I follow this program at home?

While access to a gym is useful, it is not required. If you do not have access to equipment, there are workarounds for most exercises.

How much time should I set aside on program days?

If you do everything each programmed day (and you should), the exercises take 40-60 minutes to complete.

How soon will I see results?

Great question. This, of course, varies: some folks feel distinct differences as early as the end of the first week. For others, it takes a bit longer. If done properly, you will feel better and be more likely to avoid further issues while on our program.

If I miss a week, can I go back/re-do it?

Let's start by agreeing that your progress is dependent upon your diligence. Each week, your weekly program is revealed to you. However, if you do miss a week, those are all available to you in your Member Area at any time.

Dr. Megan Graff completed her doctorate in physical therapy at Texas Woman’s University in Houston. In addition to her DPT, Megan is a Certified Strength and Conditioning Specialist, USA Track & Field Level 1 Coach and is a board-certified Orthopedic Clinical Specialist (OCS) for her advanced clinical knowledge, experience, and skills in working with patients with orthopedic conditions.
