How to throw strong punches by establishing correct posture!

What if the real secret to devastating punches and throws wasn’t muscle, but posture?

In this exclusive training session, filmed with advanced students only, master instructor Masashi Fujiwara unveils Shutetsu, a method of transmitting the body’s full weight into every strike by recruiting deep stabilizers and locking in lumbar stability.

You’ll learn not only the core principles of correct posture but also how to apply them under pressure. From sparring drills that teach distance and stability to body-strike training for both delivering and absorbing impact, every exercise is designed for real combat effectiveness.
This isn’t abstract theory. It’s a hands-on system for building power that any martial artist can use.
