A Step By Step Instruction Manual For Flexibility “When it comes to flexibility Jon Engum knows his stuff.  I had the opportunity to learn these techniques directly at one of his flexibility workshops where the results were literally instant and dramatic.  Jon Engum’s Flexible Steel is the most direct approach to effective flexibility I’ve found anywhere.  It’s a concise step-by-step manual that eliminates all the guess work.  A structured approach to stretching that tells the student exactly what stretches to do, in what order, and for exactly how many reps and sets.  If you want a no-nonsense instruction without fluff for instant and dramatic gains in flexibility, this is it.  You body will thank you, your competition will respect you and your clients will love you.” – John Scott Stevens, RKCII, CK-FMS, 5th degree black belt Taekwondo

Flexible Steel Book

A Simple System of Secrets for Regaining Your Youthful Mobility and Mastering the Art of Flexible Strength

Flexible Steel Book

7th Degree Black Belt and Taekwondo Grandmaster, Jon Engum currently displays an uncanny combination of flexibility and whipcord strength. Jon moves with speed, suppleness and enviable power—a model to his younger students

and a terror to those who face him in a fight.

But it wasn’t always this way. Because there was a time of crisis in Jon’s martial career where he began to lose his edge—from the effects of aging, plus the wear and tear of constant combat.

This book reveals the complete “Flexible Steel” system Jon Engum developed to regain and maintain his edge as a fighter. But even more importantly, Flexible Steel can give you the most priceless gift of all: the freedom to move, pain-free, with easy power, graceful strength and a sense of fluid well being.
