I am a practising martial artist, and the discipline that I practice, Tae Kwon-do, requires not only a great degree of flexibility in the leg muscles, but enormous suppleness in the joints (particularly the hips).
After reading many other flexibility books and from my own personal training, I formerly believed that I had what many would call a very large range of motion in my legs. However, after reading P. Tsatsouline's 'Super Joints, I was immediately amazed with the results.
I slid into the box splits with greater ease and with very little effort in my warm up; I performed thousands of repetitions of different kicks every workout without the aching in my knees that was all so familiar. My ankle joints became much stronger, which was very beneficial to my breaking techniques.
This book is a God-send. It helped me to develop and hone my skills as a martial artist and athlete to the a level which I, and many others, had never before witnessed.
Are you a budding martial artist? Are you a passionate athlete? Then buy this book. I can't put it simpler than that!
