The following letter is from Sangtiennoi “The Deadly Kisser” Sor. Rungroj, translated from Thai to English.

Artur Nowacki, Poland

           “He has visited me, staying and practicing at my gym since 2014.  He also assisted me with my Thai and international boxers.  Artur is a great Thai boxing trainer.  Before he arrived, I researched his profile about his boxing skills; he trained about boxing (Muay Thai) in Canada for 3 years then he came to Thailand.  His character is a perfect match for coaching Thai boxing on an advanced technique level, as he is calm, has brilliant skill, and loves to help others.  He surprised me once when we went to Ratchadamnern Boxing Stadium, where he coached my fighter in a World Class fight (Thanonchai Tor Sangtiennoi vs Sangmanee Sor Tienpo).  That day, my boxer got cut by the elbow; during the fight he was still bleeding a lot.  Artur was able to stop the bleeding of my fighter and the fight went to the full five rounds, with my fighter winning the fight.  Later my fighter had 38 stitches to his face.  This situation showed me how he is World Class.  I am so proud to have worked with him.”

Kind Regards,

 “I've been training with Artur Nowacki for two years at his gym, Nak Muay Muay Thai. He has been my primary sparring partner for my two professional world title fights and for my K-1 debut. He is a very skilled Muay Thai fighter, but equally impressive is his ability to instruct. He has brought his students’ skill level extremely high in a relatively short period of time. Everyone I've had the pleasure of training with at Nak Muay is friendly, skilled, and hardworking. Canada Island is very fortunate to have someone of Artur's skill level building Muay Thai talent.”

“I trained with Professor Artur Nowacki and his students/fighters for several of my professional Muay Thai fights in North America. Artur's passion and willingness to engage fully with his fighters is what sets him apart from other trainers. Not only is he willing to share his craft with his students but also is always learning himself and trying to make himself a better trainer. He has spent the past 6 months at Tor Sangtiennoi gym holding pads for Lumpinee level fighters and learning from a legend in the sport Sangtiennoi Sor Rungroj. In a short period of time (2 years) he has developed several fighters who can compete on a high level in Thailand and North America. I call Artur the Professor because of his scientific approach to a flowing art form. He is able to explain every technique from the inside out. I'm so grateful for the period of time I have spent with Artur and I am excited to see the next great fighters he produces.”

“Thank you for your teachings, all of them; technical, tactical and profound. The quality you wear can be seen by the depth of your explanations and how you connect them together. You paint a beautiful picture of what it is to be fully present at the moment of a fight.
I will forever be grateful that you shared your knowledge.”     

-Gabriel Rossi (Muay Thai sparring partner for Georges St-Pierre, trainer, & professional fighter)

    “I have been involved in Muay Thai for over 20 years as a fighter, trainer and a gym owner. I have travelled all over the world and seen many gyms, trainers and fighters; Artur Nowacki is one of the best trainers that I have had the honor of meeting. Not only does he understand the sport, but he understands people and how to help them reach their full potential. To see proof of this, just look at his young stable of fighters and the amazing things that they have accomplished in such a short period of time. More important than all of that though, is that the whole Nak Muay team is a great credit to the sport.”

“When Artur asked me to write a testimonial for him, I was honoured as a lot of my success can be attributed to the coaching and life lessons he has shared with me.  Most of our time together was spent in Thailand training and fighting in Muay Thai.  I never imagined I would train Muay Thai Let alone participate in competitions but when I meet Artur, he saw something in me and took me under his wing.  Artur has an innate ability to take any negative self-image you may have, break it down, make you believe in yourself and empower you to be a stronger more resilient human being.  Artur uses Muay Thai as a tool to pass on his lessons in physical, mental and spiritual strength all of which I try to incorporate into my teachings.  Without Artur’s belief in me and continual encouragement and support, I wouldn’t be in the position I am, teaching over 120 students and trying my best to inspire them as he inspired me.”

“I was always that one fat kid when I was young.  Because of my weight, I was always very shy and introverted.  Meeting people was extremely difficult for me so I spent most of my time just playing computer games.  I could no longer live my life that way as it was hurting my parents and myself so I decided to try to exercise.  That’s when I first encountered with a Muay Thai gym in Korea at the age of 16.  The Muay Thai gym was where I met Artur Nowacki for the first time.  It also hadn’t been that long for him to have started learning Muay Thai at that time.  As he didn’t really have an appropriate workout partner, we naturally got to spend a lot of time together which eventually took up the most important part of my adolescent years.  As I still struggled when meeting new people, he taught me how to treat others, how to speak English, and how to exercise properly.  In addition, we became very close as he told me what foreign cultures were like and his own travel stories.  As I spent more time with Artur, I became more confident and it allowed me to make new friends much more easily and make great memories.  I cannot describe how much I value my time I have spent with him and how much influence he has left on me to become a coach today.  He is the best coach as well as the most perfect training partner in my life who has made me the person I am today.  I send so much gratitude to my amazing Muay Thai coach Artur Nowacki for all the things he has done for me.  Thank you, Artur.”

“Last training session this morning with the legendary "Polish Professor" before he and his team head off to Thailand on Monday.  It's hard to put into words what he and I have shared over the past couple of years; there have been many challenges and hard earned victories both in and out of the ring.  Above all though are the lessons I carry forth with me, that little "Art" voice inside me that always has seen how capable I am and speaks with unwavering confidence of my abilities.  This man has taught me that I can endure and overcome anything, and I remind myself of that almost daily.  Artur Nowacki, thank you for being the coach I needed right when I needed it most.  I am forever grateful for everything we accomplished together, and the unending journey still ahead that you will always be a part of!!”
