AJ Sensei is a world class instructor. His teachings are always thoughtful and have meaning and purpose. They will increase your understanding of principles and techniques.

Books are good but seeing movement goes a long way to increasing understanding and confidence. You will not be disappointed.

The videos help the reader to avoid any confusion with the direction of the techniques and the author is very crisp in his movements and does them perfectly.

This would not only be a great supplement for those who train alone, but for a lesson on using technique in crowded spaces. Techniques are only useful if we can make them work in all situations and surroundings.

AJ has many teaching methods, he presents himself well and communicates in a way that is easy to understand, follow and practice.

Back the e-book up with the online video series and a key to The Digi Dojo and you have a world of knowledge available 24/7. Get the videos too, you will not be disappointed.

The videos were very helpful for me to make sure I was doing the moves correctly. I learn by watching and then doing so now, when I go back to the ebook, I have a picture in my head of what the moves look like.

If you're short on space but want to get stuck in to some real practice at home then the ebook combined with the videos will give you lots of guidance and ideas for training at home.

If you want your karate to improve overnight, this book and videos are a must. One of my weakest techniques is uraken, and after practicing one day with this series, I feel I have improved my uraken more than in the last year of dojo practice. Instant results!

Another example: in the video "Fall-In Junzuki", its like having AJ next to me translating the difficult to decipher 'move from tanden'. Instead of that clasically obscure explanation, he turns it into easy to understand ideas like "push your hips while maintaining posture".

The book gives you guidance, the videos give you confirmation, almost like "eureka" moments.

No matter what style you are studying at present, it's so easy to adapt to suit your own techniques and form, and then add some more of your own.

AJ shares knowledge that is next to no other instructor that you have seen on the internet.

The videos compliment all aspects of the e-book, with easy teaching methods & a very articulate teacher no other than Sensei AJ van Dijk. It’s like having AJ in your own room as a private instructor.

AJ's explanations are very clear about karate and techniques, so this book in combination with the videos will be a perfect step to do Karate in a correct way.

This book contains lots of key points that are at your fingertips and you can train straight away. I would recommend training along with the video series first though as the book acts as a great refresher.

The bits that emphasise momentum, timing, and the advanced skills to generate power exceeded my expectations, even though I'm following AJ from quite a few years.

I can go from one to the other very easily as the book and videos complement each other very well. The book is especially good if you want to train effectively but are limited with time.

Getting The Square-Meter Series will improve your karate no end technically and help you relax. They will also motivate you to train more, as there is so much to study and improve on. I watch and I read, then I want to do !

This book is different from other literature I have studied for Karate training, techniques and theory because the illustrations and reasoning are very clear and precise which enables both the senior student and novice alike

The contents of the information exceeded my expectations because AJ and his team have put together information both from knowledge gained and information gathered from other masters and instructors and home the extra mile to produce and relay the information back to the reader clearly which in my opinion has not been achieved before in the martial arts literary field.

The videos complement the book because some students thrive on being able to visualise the technique from video and watch and re-watch the videos until they start to get a better understanding of what they are attempting to learn. Some students cannot learn from black and white reading materials they need a bit more which is where the videos come in .

I have already recommended the book/videos to my students and they have already responded with a very positive attitude towards the content which is very helpful.

The book and videos will give you plenty to explore because it has plenty of bullet points and good explanations.

As they say, a picture paints a thousand words but a video will give you more.
