  • If you have a tight iliacus muscle and why.
  • The role of the iliacus in human movement and pain.

What customers say

  • Life Changer!

    I stumbled on the book “Tight Hip, Twisted Core” in a used bookstore. I took one look at the title and bought the book, because it described exactly how I felt! For years, I had been telling chiropractor after chiropractor, how I felt like one side of my body was “twisting” inward. I had been diagnosed with everything...arthritis, bursitis, sciatica.....and none of the prescribed treatments or therapies worked. Fast forward to me finding this book. Before I even finished the book, I ordered all three of the tools. These, along with the instructional videos online, have completely turned my physical and mental health around. I no longer limp. I am able to lift weights again, pain free. I can engage in everyday life and not be afraid that I’m going to fall, due to my leg buckling! I feel hopeful and normal. Do not hesitate to buy any or all of these tools. If you are “on the fence”, order these, and you’ll be able to JUMP off that fence in no time!! : )

  • Completely changed my mind about the cause of my issues.

    I only bought the book as I wished to to learn more before I invested in the equipment. After reading the book, realised that the cause of my scoliosis and lower back pain may be due to to tightness in the hips. The author explains the issues well. Now will make the investment in the equipment. The only downside for me with the PDF was the inability to use highlighting. Thinking of getting a Kindle version too.

  • Getting an Education!

    Hello, I have not had a chance to use the Range yet, as I have been reading the book! Wow, it is jam packed with so much great information. To me it is evident that most practitioners are not aware of the importance of the iliac muscle!! Your book has shed light onto why various other techniques either have not worked at all, or only provided temporary relief. I am so grateful that you took the time to put you knowledge out there so we can gain the ability to help ourselves!!

  • Informative and easy to understand

    This book provided context to why I was feeling pain and tightness in my hips. I’ve had tight hips before related to desk job, but as a distance runner and on my feet for work and parenting, I was perplexed as to why I was now getting hip pain. Through this book I understand more clearly the relationship between the muscles in the hip and the symptoms are hinting at a deeper issue: an overly activated illiopsoas. I purchased both the Hip Hook and the Mark (pressure point ball), have found pain relieve after the first use. The book helped me understand the whole system and why I was treating my illiopsoas and not my pain points in my posterior chain and abductors. Highly recommend!
