Grant Cosgrove - Arakan Martial Art Instructor

Grant Cosgrove

Senior Instructor

Grant started training Arakan in 2008 looking to improve his health and fitness.

Little did he know that Arakan was about to transform his life. Through his training, Grant lost a staggering 20 kilos and became a fitter, stronger, healthier version of himself. He thanks Arakan for giving him discipline and focus, and loves sharing his journey with others, to empower and inspire them on their journey.

Grant is a mature minded Instructor and brings a wealth of knowledge across personal development and creating a life you love. He inspires the hearts and minds of his students and walks his talk. Grant’s goal for his students is to learn how to defend themselves and loved ones, to help them achieve their goals and becoming better versions of themselves, improving their health and wellbeing along the way.

Grant trains hard and demonstrates that there is no a barrier for going after what you want in life. He is a patient and compassionate Instructor and loves teaching others to protect themselves and loved ones, to the very best of their ability.

When Grant isn’t training or teaching, he enjoys cooking, reading, travelling, listening to music and personal development. His greatest Arakan achievement is teaching Arakan to others and achieving his Orange Belt.

Student Testimonials

I was first introduced to Arakan and Instructor Grant Cosgrove with a complimentary training session several years ago and Grant has been my instructor since then. He has been inspiration, motivation and challenge all with sensitivity and care about my wellbeing and progress. Grant has been flexible with training sessions on many occasions to allow for healing from old injuries, illness and surgical procedures and other other hurdles called life, supporting me as he carefully pushes me beyond the edge of my comfort zone. He is always positive and calm as we work through the technicalities and practice of skills that are new or that I find complex and challenging; Grant does not let me give in. My Arakan journey so far has been an amazing adventure and I'm blessed to have had Grant consistently as my instructor. I look forward to his continued support and inspiration as the journey continues.

Over the past 18 months that I have trained with Grant I have gain valuable knowledge in self defense & improved to the point where I am completing  difficult techniques far beyond what I thought I would achieve.  Grant is an exceptional instructor who is professional, patient & a wealth of knowledge who can adjust his teaching strategies to make difficult movements achievable. Grant makes every session logical, effective & very enjoyable & it is very clear that Grant puts a lot of effort, thought & expertise into every session. 
I have to finally say thank you for all your effort in teaching me Arakan.  I can see how hard you work to teach this art & I appreciate that effort every session you teach.  
Thank You Grant,

Grant has been our family's instructor for over 3 years. His teaching style and approach is suitable for a great range of ages. In addition to teaching my husband and I, Grant also teaches our two young children, my teenage sister and my mother.
He is adaptable to each person's goals and abilities and always makes the class fun. I would highly recommend Grant as an instructor to people of all ages.

I would like to thank Grant from Arakan Gold Coast, for all he has done with helping me get back on in to shape after 30yrs+ of smoking. As well as the time he's put's in to my 5 year old boy Koby , he's a very shy boy who lacks confidence around other children, and to watch the change in the last year and a bit. Has been the greatest joy for me, to see and getting to train with Koby as well every week . Has helped him come out of his shell and be more focused. With everything he does , once again thank you not just to Grant but to the hole team/family for letting as be a part of this . Loving life again.

At the ripe age of 48 i felt i needed something else to focus on other than work. I had little spare time but knew that if i enjoyed what i did i would find the time.
After training privately with Grant Cosgrove for just over a year now, i have found the art has helped mind, body and spirit immensely. The training is practical, enjoyable and doesn't impact too heavily on the body unlike other arts or sports.
I also had the pleasure of attending various training seminars throughout the year at interesting locations led by Chief instructor Rob and his army of top instructors, which whilst tested the nerve, really reinforced the art in real life situations.
The respect that is shown towards the students by both fellow students & instructors is an absolute credit to the organisation, hence why it continues to grow in popularity.
If anyone of any age is considering adding something special to their personal status, take a complimentary class in Arakan as i did and enjoy the journey.

Grant has a great understanding of Luke's limits but is always encouraging him to do more and want to do more, and to incorporate the use of both sides of his body even though it is difficult. Luke loves training with Grant and there is improvements in Luke constantly. They are a perfect fit as Luke tends to talk too much and get distracted but Grant is very good at keeping him focused.

Grant has been a total professional in all aspects of training and proven himself to be an outstanding role model for my son Deklan. Grant has a wonderful ability to make training seem fun while pushing Deklan in his skills and fitness levels.

Grant is an excellent teacher and Instructor. He is incredibly patient and will answer the same question over and over in a different way until I understand. Grant is very helpful and gives/shows what real life experiences I could expect/anticipate which has made me more confident in my everyday life and I feel safer thanks to Grants training. He is an amazing Instructor because I have watched him train my mum and he does an incredible job with her and adapting to my mums learning style.

My son Deklan is a naturally kind and gentle boy, who as an only child has never had to endure the competition and ruff and tumble of other siblings. Reading how daunting and challenging schools can be these days I was very keen to get him involved in self defense but wasn’t sure what was going to be the best fit for him.

In a chance encounter at a community fate we saw the Arakan stand and after talking to the guys I was really impressed with how friendly the team was and how passionate they were to get Deklan into his first lesson. And here is the part that grabbed me the most, the training is done outdoors in parks and school grounds while wearing shirts and shorts and everyday shoes, now that’s real life training. We booked in straight away for our complimentary lesson and Deklan couldn’t wait to get started.

On the day of his first lesson Deklan was quite nervous but Ryan his instructor made him feel completely relaxed and the lesson was a great mix of training and learning through fun games. At the end of the lesson Deklan ran straight up to me and asked if he could do more training tomorrow and the next day, which was a sure sign he loved it. He has now been training for over 3 years and as much as Arakan is about learning self defense and getting fit I have seen Deklan grow in confidence, co-ordination, self respect and self belief. 

Deklan now jumps at every opportunity to do extra lessons and group training and he totally loves going to school holiday training days and he wears his Arakan uniform with absolute pride.

I can honestly say I have been totally impressed with how Arakan has taught him practical, useable skills in real life environments and we look forward to many more years involvement with the Arakan family.

Watch how Arakan has changed the lives of our students

Being in the Moment
Contrary to what many people think, a long term disciplined practice in martial arts can help you become more tolerant, calm and peaceful, rather than aggressive. 
Many people avoid training in a martial art because they’re “not a violent person”,  in fact, it’s a misconception that martial arts equates to violence.  This misconception actually robs people of a martial arts journey as well as the massive array of benefits that form part of that journey.

Time - the key to success

In todays’ society we expect so much so quickly. There is always so much pressure on ourselves and people around us to gain immediate results, no matter what the venture maybe. 

Our concept of time has changed dramatically; I often hear comments such as, “I have been training for so long now, it’s been almost three years,” and “I have given myself three months to see if my new business can make big profits,” and “it’s time to find a new job, I have been in this same job for two years, it’s been too long.”

Malcolm Gladwell, in his book Outliers states that it takes 10,000 hours for someone to master a topic...
