Nicolas Poltipoulos
Ju Jitsu Blue Tip CourseBeing a lifelong martial artist, I was skeptical of joining online martial arts training. I researched a few options and came upon Northstar Ju Jitsu and the Mastery Academy. I am so happy I did. I have really enjoyed the training so far. The Mastery Academy has so much to offer. It’s changing my life, it will change yours for the better. Five stars.
Mike Mejia
NSJJ Mastery AcademyI have found these courses essential for perfecting my technique. Along with my practice in the Dojo, my training has become a more well rounded experience over all. I can learn at my own pace at home. With the well structured videos it leaves no questions unanswered. I’ve also found them invaluable before grading.
Keith Hennessy
Ju Jitsu Yellow Belt CourseDoing these tutorials is extremely helpful, particularly for the higher belt grades as complexity of the self and multiple defences increase significantly. You get the most out of the dojo sessions if you study the curriculum at home and just have to practice the application in class – this way you get confident for the grading in no time!
Jonas Schoefer
Ju Jitsu Brown BeltA great source of information. This was a huge help for me learning and understanding the new multiple defence. I was able to watch Angus over and over again to ensure I was getting it right. The instruction for the self defence and ground defence was also invaluable. I’m sure these course will be utilised many times.
Michelle
Ju Jitsu Red Tip CourseI have found these online tools invaluable to adding that extra dimension to training. We all learn in various ways and being very visual, I find it a great tool. Having Andy Sensei and the senior students using foundation techniques, and explanations that I can watch on my phone while travelling, keeps my finger on the pulse anywhere. Thanks Andy Sensei

Ju Jitsu Blue Belt CourseUnique And Invaluable Lessons The lessons I have learned during from the Northstar program have also been unique and invaluable. On Saturday night I was lucky enough to be taken along to the Rugby league test (Oz vs England), and it was my Northstar training that allowed me to not only avoid a vicious alcohol fueled brawl right next to where I was sitting, but also to identify the looming fight and assist my hosts in getting out of the danger area promptly. Thanks once again for your interest and willingness to help me to progress

NSJJ StudentNorthStar Has (And Continues) To Help Me With My Inner Demons For a while pre joining, for a long time after and occasionally now, I have suffered from depression. NorthStar has (and continues) to help me with my inner demons….it has been the best drug whenever I feel down.
John
NSJJ StudentIncredible influence Drew and Martin have had an incredible influence on Atlas in the short time he has been coming. He was quite withdrawn and lacking confidence. He was finding it difficult to play with other children and hurting his little brother a lot. 6 months later he is now playing with lots of children, speaking up if play gets rough with other kids and not hurting his little brother. He talks often about Drew and Martin and says ‘What would Mr Drew do?’ if something is hard or scary. You have amazing teachers and Atlas and ourselves will miss your classes greatly. I hope to find somewhere else to provide such strong male role models for our kids outside of their father.

Victoria
Mum of NSJJ StudentsTerrific grading Just wanted to drop you a line and say thank you for a terrific grading last Sunday at North Sydney. Ben is so proud of himself for gaining his Junior Black Belt. It is wonderful to see him achieve something he has worked so hard towards, through hard work and dedication. A huge thank you to Angus and Carlos for working with him towards this. We look forward to seeing him continue to grow and develop at Northstar. Thank you and kind regards
