In tonight's online International Black Belt Class, we spent the full hour breaking down the hows and whys of Long Form 3.

Everyone was awesome, and we had representation from Chile, the USA, and Canada.

A key message from today's class was this: Be humble and eager to learn, and knowledge and skill will follow.

Earlier in the day, Heteng Zhang took a 1-hour private lesson and worked on the following: B5a, B5b, B5aP, B5bP, B5aPbk, B5aPhk, B5aPbkhk, B5aPhkbk, Swinging Pendulum, Crushing Hammer, Captured Leaves, Evading the Storm, Charging Ram, Parting Wings, Thundering Hammers, and Coordination Set 1.

Today I taught a Gracie Jiu-Jitsu private lesson to Josh Girges, a 4th Degree American Kenpo Black Belt at SMAA.

Today's session focused on practical self-defense applications, including a body-fold takedown against haymaker punches, a half-nelson takedown in response to a two-straight-punch attack, and a counter to a cross-collar lapel grab.

We also covered wrist-grab escapes (same-side, cross-wrist, and two-on-one variations), defense against a single-hand push, two effective counters to a two-hand push attack, and a hammerlock in response to a single lapel grab.

Great training session focused on timing, leverage, and applying simple, effective techniques under pressure.

Today at SMAA, I taught two private lessons and one group class, covering a combination of American Kenpo and Gracie Jiu-Jitsu.

During the first private lesson, Brennan Weatherhead worked on American Kenpo freestyle and self-defense techniques. His training included Blue Belt freestyle techniques (R/L): B1aPHrk, B1bPHrk, B2aPHrk, B2bPHrk, B3aPHrk, B3bPHrk, B4aPHrk, B4bPHrk, B5aPHrk, B5bPHrk, B6ahKbkls, B6bhKbkls, B1arKsrK, B1brKsrK, B3asKrKsrK, B3bsKrKsrK, B5atsKrK, B5btsKrK, B6arsK6hK, and B6brsK6hK. He also reviewed Green Belt freestyle techniques (R-R), including Green/Orange (R-R): B1a, B1b, B2a, B2b, B3a, B3b, B4a, B4b, as well as the Green Belt extensions Detour from Doom, Squatting Sacrifice, and Escape from Death.

In the group class, Dave Wolfe, Scott Wolfe, and Darren Wynes worked on Gracie Jiu-Jitsu self-defense techniques from a standing position, focusing on defenses from a distance as well as responses to grips and holds. The class covered a body fold takedown against haymaker punches, a half-nelson takedown against straight punches, a single-leg takedown off a fake front kick, single- and double-leg takedowns in response to an attempted grab, single- and double-leg takedowns from a collar-and-elbow clinch, a leg hook takedown, and a deep cross-collar lapel grab escape. They also reviewed three wrist grab escapes, including same-side, cross-wrist, and two-on-one variations, along with a push defense that transitioned into a wrist lock.

During the final private lesson, Darren Wynes worked on Gracie Jiu-Jitsu defenses against front and rear grips and holds. His training included two defenses against a two-hand push (high and low), two shoulder grab defenses (straight and bent), three single lapel grab defenses (hammerlock, chop and wrist lock, and wrist throw), and two defenses against a two-hand lapel grab (narrow grip and wide grip). He also practiced a shoulder push defense from behind, two rear choke defenses featuring an Americana shoulder lock takedown and a hip toss, and three wall-defense counters covering push counters, a single-hand choke, and a two-hand choke.

We had a special Black Belt class today as we welcomed Karri Barnes, who made the trip from Ohio to train with us in person.

In Kenpo, the class worked on Blocking Set 2, Delayed Sword, Five Swords (Extension), Hooking Wings (Extension), Raking Mace, Kneel of Compulsion, Snakes of Wisdom, and Marriage of the Rams.
