We all know that good and rational training is the most important ingredient of health and prowess. But what is the standpoint of scientists in this topic? Why should we stretch? Why should we train a few times per week? What can be the cause of chronic lumbar pain? What is fascia and how does it work?

If you are interested in scientific explanation of what is hidden under Flexible Steel training, follow our recommendation and watch the documentary below:

It has become a yearly tradition to set ourselves new goals for the coming 12 months. For some it’s a start of a long journey towards desired skills. For others, it’s merely a formality to achieve their goals. While the advanced will want to take their abilities to the next level.

The Flexible Steel 5 – featuring Andżelika Stefańska-Kowalik from Poland, member of the international FSIS team

All the below moves are high-level techniques that require both strength and flexibility. Please, understand these are our flagship, end-range movements, but inside Flexible Steel we have progressions for each that will allow even the most inflexible student to safely begin training at his or her current level.

1️⃣ Split Press
The move that started it all. Get into a front split or martial arts split and press a kettlebell. Gold standard weight: men 32kg, women 20kg. Introduced into the system by Jon Engum.
2️⃣ The Gauntlet
Very challenging combination movement that includes a pike, straddle, and cobra, and the reverse of these moves. Introduced into the system by Patrice Remarck.
3️⃣ The Gazelle
Front split switches done between boxes using as much leg strength to rise up as possible. Introduced to the system by Jon Engum.
4️⃣ The Split Up
Front split combined with a push-up. Introduced to the system by Andżelika Stefańska-Kowalik.
5️⃣ The Loaded Frog
Part armbar, part get-up, and part frog. Inspired by Mike Perry’s get-up variation, developed by Jon Engum and Louka Kurcer.

We encourage you to try one or all exercises from Flexible Steel 5. Keep us posted on your results!

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.
