If you’re a weekend warrior or you’re admittedly out of shape, you probably know all about sore muscles, stiff joints, and the battle you have to fight every morning to get out of bed. You may even be in good physical condition and a well-trained athlete, but experience joint pain and stiffness that can hinder your workouts and competitive edge.

In Flexible Steel, Engum recounts his own experience with losing his edge, feeling the strain of tight muscles, sore joints, and a lack of flexibility. And he describes in detail how being an aging 7th Degree Blackbelt and Taekwando Grandmaster motivated him to find a way to improve flexibility and joint strength to remain at the top of his game. He studied flexibility, meditation, and biomechanics from the best gurus and practitioners in the business for over a year. His quest for ultimate flexibility even included training from the legendary bodyweight training expert Pavel Tsatsouline.

Based on his exhaustive, hands-on research, Engum developed the Flexible Steel training program. Early in the book he lays the foundation for Flexible Steel by explaining the three big S’s of stretching: strength, space, and spread. This training strategy helps improve strength, range of motion and flexibility, and joint health needed for squats, kicks, splits, and other exercises. You’ll learn proper technique to execute stretches to improve the strength and flexibility of every joint and muscle group in your body. Once you learn these basic principles and some beginner and intermediate stretches, Engum shows you how to master the hallmark move of flexibility: the splits. You’ll learn the techniques and stretches necessary to master this move and improve flexibility throughout your body in the process. You’ll be stronger, fitter, more flexible, and less prone to injury.


Martial arts expert Jon Engum provides a solid program to improve flexibility, mobility, and joint strength in Flexible Steel that is suitable for all ability levels.


Some of the flexibility exercises are ones used by many other fitness practitioners. While the exercises may not be new, Engum provides a fresh perspective on these flexibilty exercises.
