Chokushin — Unlocking Explosive Power in Grappling and Striking

Strong muscles. Weak output. Sound familiar? That's because you're relying on the wrong muscles.
Shutetsu method teaches you how to channel your deep stabilizers instead of using your surface muscles.

Learn how to activate your deep stabilizers and unlock explosive power!
When your body moves as one, power flows from the ground in any position.

Volume 2 applies the Chokushin structural system to real combat applications, integrating ground reaction force into striking and grappling.
