To truly master martial arts, we must become one with our partner—to be in sync, to know their mind. This isn’t abstract philosophy; it’s a real-time, second-by-second practice. Our opponents, through their very actions, plant the seeds of their own defeat.

Cheng Hsin is an excellent supplement for students of standing-grappling and throwing arts (Aikido, Japanese Jujutsu, Hapkido, Chin Na, etc.), as well as for anyone seeking a fun and skill-intensive introduction to martial arts.

The art was developed by Peter Ralston, a master fighter who, after mastering all the martial arts available and dominating the martial arts scene in the 1970 and 80s, realized that his success came not from technique, but from his real-time relationship with opponents. Cheng Hsin is his legacy—a system designed to pass that profound insight on.

This Aikido-adjacent art explores joint locks and throws, but focusing on this field from the experience of competitive martial arts. How do we train to take on any opponent, including ones that are stronger, younger, and more athletic than us? How do we train in a safe, fun, and skill oriented manner that supports insight and expertise?
