Seabrook Martial Arts Academy has been serving London, Ontario, since August 1995. All classes are taught by 7th Degree American Kenpo Karate Black Belt, Jamie Seabrook. Unlike many schools that will promote young children to black belt, here at Seabrook Martial Arts Academy you will earn your rank through years of commitment. Our focus is street self-defense, not sport.

Advanced Black Belt Grading
Last night I tested my first two students ever to 5th Degree Black Belt in American Kenpo Karate - Matt Trejo and Evan Wiley. Additionally, Darren Wynes was promoted to 4th Degree Black Belt. As part of their test, the three candidates performed all 154 American Kenpo techniques (+ Aggressive Twins, Spreading Branch, and Intellectual Departure), all 96 technique extensions, and Long Forms 4-8. Each candidate also had several stand-up sparring fights, and several fights on the ground.
Unlike many advanced black belt promotions at this level which are considered "honorary" based on "time in the art", or that require students to perform 5-10 of their favorite techniques based on a 5-minute test, these three candidates did a 3-hour grading and performed every self-defense technique in the system. That's how a promotion at this level should be - and these three exemplified what 5th and 4th degree black belts in American Kenpo should move like.

Noah Bragg Promoted to Junior Black Belt
Last night, Noah Bragg was promoted to Junior Black Belt in American Kenpo Karate after more than 6 years of training at Seabrook Martial Arts Academy in London, Ontario. His testing consisted of full-contact continuous stand-up sparring, a jiu jitsu roll (ground fight), and American Kenpo forms and sets. The pictures on the left were from his Junior Black Belt testing and those on the right are from when he was still a beginner at our school. Congratulations Noah!

When to Use a Modified Mount
One reason to use a modified mount is when the opponent is trying to use an elbow escape to get out of the mount position. When their elbow or hand pushes on our knee, immediately modify the mount to take away their elbow escape attempt. The modified mount is effective because it decreases the likelihood that the person trying to do an elbow escape can hook your foot that is now located in the opponent's stomach. Additionally, a modified mount is more advantageous than a full mount when the opponent rolls over to their side.

Escaping the High Mount Position
When you are being mounted and your opponent is sitting low on your hips, the elbow escape, trap and roll technique, and hip thrusts are very good options to escape. However, these techniques don't work well when the opponent is able to establish a high mount on you. Although it's possible for you to wiggle back down to try these same techniques, sometimes the opponent is effective at maintaining the high mount. In this situation, a good strategy is to place your hands in the opponent's armpits with stiff arms (assuming his hands are on the ground), bump your hips, and to place your feet quickly in the opponent's armpits to come out the back door to escape.

Women's Assault Prevention Seminar
On October 19, 2018, Matt Trejo and I teamed up to teach a women's assault prevention seminar in London, Ontario. The class was packed! We taught how to strike effectively, how to establish a strong base, and how to defend against front chokes, wrist grabs, bear hugs, and to defend if you are on the ground and the opponent is on top of you. We also taught self-defense techniques against hair grabs and rear chokes. More seminars to come!

Maverick Helicopter Ride in Las Vegas
Last night Chantel and I had the opportunity to take a helicopter ride over the strip in Las Vegas for our wedding anniversary. We had such a great time and I highly recommend taking this ride if you are ever in Las Vegas.

Swinging Pendulum - Common Problem
I thought I would share a common problem I see in students when practicing Swinging Pendulum (although this could apply for any technique in Kenpo that starts in a neutral bow where we move up the circle to get out of the way of an attack). When the roundhouse kick comes at us, and we step back with our left foot and use a positional universal block to the opponent's kick, be sure that your feet are in a straight line and that they don't cross. In other words, stepping back too far with your left foot so that it is behind your right foot means that you are getting in your own way, thus limiting your ability to effectively use your back leg.

Kenpo Karate Techniques on YouTube
Hi Everyone,
I have decided to put every Kenpo Karate self-defence technique that I teach at Seabrook Martial Arts Academy up on YouTube. This will obviously take some time, but my goal is to have each video lasting anywhere from 1-5 minutes so that someone watching it can get a broad understanding of the application of the technique, and demonstrated at a high level of proficiency. Obviously, the more advanced the self-defense technique, the longer the video will be. The techniques will not be put up in any sequential order, but they will all eventually be available. A couple of days ago, I uploaded Delayed Sword, Lone Kimono, and Five Swords.
