“Lots of people have asked me about advanced flexibility training since they can do this or that & are looking for the next step in their training.  If you’re looking for an easy-to-follow format that’s going to get you more mobile in a manner that’s still going to give you quick-twitch strength, I strongly recommend that you peep this work by my colleague, Jon Engum.  Engum is a Master RKC strength training professional & a legitimate 7th degree Taekwondo black belt who can  COMPLETELY walk the talk.  This book gives you the fast-track insights into the training methods that he’s used to turn the below-average Jon into flexible steel.” – Dr. Mark Cheng, Los Angeles, CA

Flexible Steel Turned Back Time “When Jon Engum presented this material in a workshop, I had two questions: 1) Can I get my kicks back and 2) would I be able to see the return of a split.  The answer was yes and yes on both counts.  The drills presented in this book will get your flexibility goals in an insanely fast period of time.  With my background in Chiropractic, I have seen many different flexibility modalities and Jon has taken these principles and made them accessible for everyone.  If you work on the program as laid out you will improve.  PERIOD.  And even better…Master Engum isn’t just peddling theory.  He is a living breathing example that this system works and he also has a growing list of student to prove it.  Don’t take my word for it however.  Practice the drills and convince yourselves that Flexible Steel is a gold mine for your flexibility training.” – Dr. Prentiss Rhodes, Chicago, IL

“Just finished reading Jon Engum’s new book Flexible Steel.  It is excellent explanation of both the methodology of stretching and how to apply it into your own program to safely, quickly and effectively take your flexibility to places you never thought possible.  It is the perfect companion to Pavel’s Relax into Stretch.” – David Whitley, “Iron Tamer Dave” Master RKC

“Great techniques that really work.  I just this spring had the privilege to become one of Grandmaster John’s students both in Taekwondo and Kettlebells. He has incorporated the techniques in his book into his classes. As a soldier it is vital that I remain both strong and agile. I came into his teachings from a background of heavy lifting with little emphasis on mobility. I have gained inches of flexibility and retained my strength. Now I have a guide I can take anywhere I go. This book gives a detailed guide on how to revitalize your body and move with power and grace. It is easy to follow and as I can personally attest, effective. I look forward to accomplishing the splits as a 30 year old.” – Shawn Jacobson / Randall, MN, USA
Even us Old Folks“As an older adult and having been desk bound for 30 years with little exercise, I find this very helpful.  Adjusting it for my age and physical condition, I am progressing and very well pleased.  The range of motion exercises are expecially helpful.” – Miriam Brougher / Elizabethtown, KY, USA
