More incredible work put in by Heteng Zhang today, who spent an hour working with me on Long Form 3.

Heteng is a great martial artist and an even better person. Below is a picture of us from a few weeks ago when he traveled all the way from Edmonton, Alberta, to London, Ontario.

Grateful for the time, effort, and dedication he continues to put in.

We had a great class today at SMAA.

In the morning, Mike Klusman, Karri Barnes, Ivan Valdivia, and Lori and Mac Herrington, worked on the first 12 moves of the Kenpo Club Set, as well as Thrust into Darkness and Circling Fans.

Awesome!

Back-to-back days of solid training here at SMAA, with continuous sparring, Kenpo self-defense techniques, sets, and forms.

Last night, Shaun Thornhill took a two-hour private lesson and reviewed all 24 Orange Belt extensions, Blocking Set 2, Thrust into Darkness, and Circling Fans. Shaun will be testing for his 2nd Degree Black Belt in December 2026.

Today, Dave Wolfe and Cheryl Twist took a two-hour semi-private lesson and reviewed Long Form 5, Deflecting Hammer, Grasp of Death, Flashing Mace, Encounter with Danger, Courting the Tiger, Prance of the Tiger, and the extensions to Obscure Sword and Squeezing the Peach. The class wrapped up with continuous sparring to put everything into practice.

Great work on some advanced material in our online international Black Belt class this evening!

We covered Kicking Set 2 from American Kenpo, as well as three Espada y Daga drills from Modern Arnis.

Amazing work, everyone!

Two private lessons tonight at SMAA, with a great mix of American Kenpo and Gracie Jiu-Jitsu.

In the first lesson, Josh Girges worked through Long Form 7, the extensions to Fallen Cross and Returning Storm, and Kicking Set 1 from American Kenpo.

For Gracie Jiu-Jitsu, he covered the palm-up cross choke from the kneeling position, closed guard, and mount; four defenses against the cross-collar choke; two counters to the cross choke from closed guard; the baseball bat choke from knee-on-belly; three variations of the bow-and-arrow choke; the rat-trap Americana armlock from side mount; and a standing clinch against an aggressive fighter.

In the second lesson, Karri Barnes spent the entire session exploring the hows and whys of Short Form 3, with particular attention to reverses and opposites. She has an outstanding Short 3, and it was great to see her really digging into the principles behind the form rather than simply memorizing the sequence. What an outstanding black belt!

Tonight I taught a Brazilian Jiu-Jitsu class at Sherbourne Martial Arts Academy focused on side mount escapes and the Punch Block Series from closed guard.

We worked through four side mount hip escapes: standard, thigh drive, top knee through, and hip and shoulder, along with Stages 1–2 of the Punch Block Series. Good times and good training!

Some solid training at SMAA today!

First, Brennan Weatherhead took a one-hour private lesson, focusing on Club Set and Long Form 5.

Following that, Brennan, Callen Clark, and Tommy Shepherd put in a two-hour group session covering continuous sparring, kickboxing line drills, Raking Mace, Shield & Mace, Fallen Cross, Short Form 3, Single Sinawali, Double Sinawali x2, and Visadario 6-Count.

A great day of hard work, skill development, and putting in the reps!

Today was one of the best Brazilian Jiu-Jitsu (BJJ) classes I’ve had in 2026.

Taught by BJJ black belt Mike Pol, the class brought together one blue belt, two purple belts, one brown belt, and one black belt. We worked on side mount maintenance and escapes, transitioning from side mount to mount, the hip escape, rollover escape, and ghost escape from side mount, as well as a bread cutter counter to the ghost escape.

To top it all off, everyone had the opportunity to roll with each other. It was an excellent resistance class, with great technique, challenging rounds, and a fantastic group of training partners!

With more rank comes more responsibility. That responsibility includes continually acquiring knowledge, refining skill, practicing humility and self-control, and, perhaps most importantly, spending more, not less, time on the mat. There is an old saying that goes:

“Miss one class, you notice. Miss two, your instructor notices. Miss three, everyone notices.”

That mindset is exemplified by Shaun Thornhill, a 1st Degree American Kenpo Black Belt who spends one hour with me in person every week for private instruction, and sometimes puts in two-hour private lessons as well.

Tonight, Shaun reviewed Coordination Set 2, Long Form 3, Leap from Danger, Circles of Protection, Capturing the Storm, Conquering Shield, Kneel of Compulsion, Clipping the Storm, Glancing Wing, The Back Breaker, as well as the Orange Belt extensions to Clutching Feathers and Triggered Salute.

Shaun continues to demonstrate the dedication, discipline, and perseverance that come with taking his training seriously.

Amazing work and perseverance, Shaun!
