John Gill in my opinion is one of the top teaching martial arts instructors in the world as his drive for success in everything he does and the passion he has in teaching his students is just amazing.
I was a student of Johns classes and not only did I respect him because of his very high ranking and the fact that his black belts were of such a very high standard but also the way he brought the very best out of all of his students and the way he inspired them.
If your looking for a great way to get fit and learn a style of self defence that will give you great confidence in looking after yourself and will enhance your focus and drive in everything you do then you have found it.
Johns classes are perfect for all ages and bringing a friend with you is a great way to train together.
Also he has a great video you can download and and an online learning system
Best wishes with your training
