A Black Belts Nightmare

303’s current Head MMA Coach also happens to be one of Colorados very best WelterWeight Fighters and my good friend.   If you have never seen him fight and you are a fan of MMA then I promise you, you will be a big fan after seeing this man go after his opponents with a persistence that one can only describe as frightening.  He just keeps going, he just gets stronger, and he enjoys the hurt. No doubt he wants it more!  He has hate in his strikes.  These are the vibes he is throwing and all his opponents and fans can feel it. 

Art "THE ARMENIAN NIGHTMARE” Petrosyan is truly a nightmare in all aspects of MMA.  Possessing heavy punches in both hands and always seemingly able to place well timed kicks, knees and elbows, makes this Armenian born fighter a very bad dream for anyone that cannot withstand his heavy onslaughts.  Not that taking him down is an easy task for anyone that is not an exceptionally high level wrestler but even then it is no picnic. On the ground Art is well versed in defense and submissions and not easily fooled and never surprised.  Art eats sleeps and breathes combat arts and has lived on the mat for over a decade grappling all the best Colorado has had to offer and wherever he may find them.  What does this all amount to?  Well for starters The Sparta Champion has not lost a fight since 2017 and has the youth, strength and experience to make a serious run at the UFC.  

First however the 30 year old 303 Coach and fighter must get through a seasoned vet and very tough challenger by the name of Charles Hayward who himself is a Jiu Jitsu Black Belt and respected competitor with a total of 31 Pro MMA fights with 17 wins and  many of them over very well known and respected fighters. Mr. Hayward is what we like to call a “Game Opponent!”

  So how will our 303 Coach handle this kind of fighter?

Will Art Stay away from the Black belt and batter him from a distance? 

Will he put Charles against the cage and hold him there punish him and win that kind of way?

Or will he beat the Black Belt at his own game and take the fight to the ground and sub him? 

This is why I love MMA!  There is so many ways to win… or lose for that matter. 

 Either way I would bet the yacht (if I had one) on Art Petrosyan!


Because of the fact I have personally witnessed his development for over ten years on and off the mat.  Seeing him time and time again working, training and fighting amongst the very best Colorado has had to offer.

Art Petrosyans MMA skills have been defined over the years in many versatile ways but one of the most defined ways for sure is he has defined the ability to completely dismantle an opponent with the particular set of skills in which Mr. Hayward possesses. 

I mean that with 100% respect to Charles his skills and his entire camp.

We are actually big fans of Charles Hayward and love the way he grapples, carries himself and fights!  Just not so much in the case of this fight… and yes, I am bias.    

All I know is I can’t wait to see these two true professionals throw down this Saturday night!! 

Let’s go ART!!!!


This fight will take place this Saturday In Aurora, Colorado at the Arpahoe County Fairgrounds. 

Purchase tickets below by following the link and putting “PETROSYAN” in all caps so Coach Art gets credit for the ticket sell.

NEWS & UPDATES: Art Petrosyan Article

The True King of Sparta

 Have you ever heard of the term “Street Legend”?  The Urban dictionary defines the term as “A legend of the streets, someone who has earned respect through the streets.” 

 Well, if there ever was a version of “Street Legend" in MMA then certainly LT “SMASH” Nelson would be one name that jumps to mind immediately or at least it would for all that know Colorado MMA.   

 After all, at only 32 years old the South African native has competed in just about every sort of combat event one can think of.  From MMA at the top level to Bare knuckle championships that were won in a devastating violent fashion.  His Lethwei debut and victory is one of the best displays of all out fighting you will ever see. If you are not familiar with Lethwei then just think of the movie "Blood Sport"  He has also competed in Boxing, kickboxing and Muay Thai and always at the utmost top Professional levels. His Glory kickboxing record is amongst the best in the World and all his fights and I mean ALL his fights are must watch tv!

 Truly LT has seen it all in the combat sports world and has always fought and trained with some of the very best fighters in the world and almost all of the best fighters in Colorado since he was 19 years old. 

  Ironically Lt made his pro debut against the 303 Training Center back in 2011.  His fight was against our tough, relentless and loved Joe "The Sicilian Terror" Guerra.  LT won that fight after two bloody rounds via a submission. From that day on we would always have a special even profound connection with Mr. Smash Nelson who would later fight for the 303 brand many times, then while still fighting became the Head 303 MMA Coach from 2019-2022. During that time The South African born and loved 303 fighter would amount other incredible achievements.  Among these achievements "Smash" would win the very coveted $10,000 prize and “King of Sparta” Title TWO times in TWO different weight classes! 

 In the summer of 2022 the feared LT would move to Oklahoma where new opportunities would lead him to instant success in the bare knuckle boxing world including titles, instant classics and FOTY nominations.  

 Now he is back in Colorado and on a mission to defend his 155lbs King of Sparta Title and win the $10,000 prize for a record third time! 

 This card is absolutely stacked and to win it all our 303 Legend must get through all three fights including the possibility of facing well known and very respected UFC veteran Luis “Violent Bob Ross” Antonio Peña.  

 This has potential to be the MMA Event of the year!  Buy tickets now by clicking the link below and putting the code “NELSON” in all caps so Coach LT gets credit for the tickets!

 This card will feature TWO of 303 Training Centers very own Coaches including our current MMA coach, manager and Sparta Champion Art Petrosyan!  If I could only pick 2 or 3 MMA event to go to this year than this would certainly be on the list! So Let's go scream our support! 




Featherweight Champ Nick Montez!

Nick Montez becomes the new "King Of Sparta" Featherweight Champion and he does it in spectacular fashion! The "Mile High Menace" started off his historic night with a spectacular 1st round TKO in the Boxing portion of this event. His second fight of the night would take place under Colorado Amateur Kickboxing rules and would prove to be Nicks toughest challenge of the night. Nick would overcome his opponent through his relentless attacks and outright determination. This would win him a decision and the opportunity for the $3000.00 grand prize and to become the new Sparta Featherweight Champion.  

 Getting to this portion of the event is quite a challenge in itself, both fights have different sets of rules (Boxing and Kickboxing) but you also have to win both of those fights. Winning both gets you a chance to fight a three round MMA fight for the $3000.00 prize and Featherweight Title.   

Nick came out the first round like a man on a mission that was as fresh as his first fight and he never eased up, not even for a second.  Any opportunity the "Mile High Menace” had to hit his opponent he did and he did so with what looked to be vitriol. Every punch was thrown with bad intentions along with every knee to the body and takedown. For three rounds Nick battered and beat his opponent until the very last second of the last bell. This final display of power would earn him the victory, the Featherweight Title the $3000.00 and only the second 303 Training Center fighter in a decade to win this unbelievably challenging MMA event.  

We want to send our gratitude to all of Nick's opponents for the evening who were all tough, skilled, and game opponents. A special thanks to Jeff Cisneros and the entire Sparta Combat organization for always putting on incredibly well run MMA events.

  We also want to thank all his Coaches, especially Art Petrosyan and Kevin Jacobe. Without them this hardly would have been possible. 

Along with our coaches we also had a great amount of help from Jake Ramos and the entire Genesis Academy.  Please check them out if you are in the Arvada area and want the best MMA academy in Colorado. Tell them 303 sent you! 

And finally, we want to say, Thanks to Nick Montez for representing the 303 Training Center, his coaches, family friends and fans with such class, honor and respect. You truly represent all the characteristics of a great champion. We can hardly wait to see what the future brings for you Nick! Your accomplishment will always be remembered here at 303!

Blue is the color of Tiger lilies

Don't let this little girl's adorable name fool you. She is as sweet as she is fierce and that is saying a lot! The color of this belt promotion is very special considering not only is it just BLUE, but Blue belt marks a full year of Brazilian Jiu Jitsu training just like the adult belt system does! You can imagine how pumped a hard working little student like herself is being able to say she has been training for a year! The coolest thing about her getting on the mats is it got her father and assistant coach Billy back into training BJJ as well! Which is all around very inspiring. Keep encouraging people on and off the mat Tigerlily!

Congrats on the blue belt Tigerlily!

$3000.00 Prize On The Line For The Mile High Menace

In a sport full of nicknames, you might be hard pressed to find a fighter with a better suited nickname for their style than Nick Montez. 

The 26 year old up and coming 303 Training Center fighter fights with a ferocity, power and seemingly endless gas tank that will surely make you a fan from the moment the bell rings.   

As an amateur fighter The Mile High Menace is as well rounded as any up and coming professional fighter which makes him a true threat to all contenders no matter where the fight may go.  

Why is being well rounded so important? Well outside the obvious reasons... being well rounded is particularly valuable when there is $3000.00 on line for possessing such abilities.

 Yep, that’s right $3000.00.


"Wait" you might say! 

Nick is a 2-0 amateur fighter, how can he make $3000.00?  You would be right to wonder such a question.  

Just to give you a little context on how much money that is for a fighter. Let's just say most all fighters making their professional debut only make $500.00 to show and $500.00 to win. 

 So, this is definitely an unbelievable opportunity for any fighter much less an amateur fighter.  

 The way Nick can accomplish this is by winning the very prestigious "KING OF SPARTA FEATHERWEIGHT ELIMINATION TOURNAMENT” on January 21st at the Arapahoe County Fairgrounds in Aurora, Colorado.

The tournament itself is a unique one of a kind tournament that requires fighters to participate in a Boxing match, Kickboxing match and an MMA fight all in one night! 

This is a single elimination tournament so to win it all and the $3000.00 prize you must win all three fights in the order mentioned above.  

Nick Montez is truly an up and coming star and there has not been a 303 Training Center fighter better equipped to win this tournament since the last time we witnessed Coach LT “Smash" Nelson become The King of Sparta and win it all in dramatic fashion at the professional level twice in two different weight classes!  

Buy your tickets now by following the link below and putting the CODE  “MONTEZ” in all CAPS so Nick gets credited for the tickets!  

So bring your loudest cheers and join your 303 Training Center Jiu Jitsu and kickboxing family on the 21st of this month as Nick “The Mile High Menace” looks to make his name live forever in the halls of the 303 Training Center by becoming the 2nd fighter off our mats to be the next KING OF SPARTA!
