JAKE MARTINEZ

[Brazilian Jiu-Jitsu ]

My Jiu-Jitsu journey started at Xtreme Couture in Vancouver, WA in 2007. Walking into that gym was both terrifying and exciting. Out of shape and never having played sports, I wanted to quit 10 minutes into my first class. Feeling that I had made a terrible mistake and was ready to walk off the mat, I was given a promise from my instructor “come in every day for 30 days and you’ll never quit”. It made me angry, so angry, that I showed up to every class just to show him that I didn’t want this and that I wasn’t going to renew my contract. After a few weeks my anger faded, the workouts got easier, and 30 days later I signed a 1-year contract. The next few years would be spent rolling 7 days a week gi and no-gi, wrestling, going from 290lbs to 220lbs, and competing around the northwest with my first coach and BJJ black belt Chris Dealy.

No matter how small or weak you think you are, you can train Jiu-Jitsu with consistency and patience.

ROBBIE Baltzell

[Muay Thai]

In learning how to help others, Robbie learned the hard way that it is also important to help one’s self. During graduate coursework in counseling, Robbie took up Muay Thai and has since made it an important point to incorporate its discipline and philosophies into a life practice. In doing so, Robbie has found value in Muay Thai’s teaching of a new level of mindfulness of one’s own body. Robbie’s belief is that a person can incorporate this mindfulness into a new understanding of the person’s sense of self and the world around them. Robbie also tries, (and may or may not be successful) to incorporate humor and admittedly nerdy pop culture references in his explanations of techniques. In addition to coaching and training at SBG Idaho, Robbie also serves as a Licensed Clinical Professional Counselor in multiple locations throughout the Treasure Valley. Robbie often enjoys water and snow sports with other members of the SBG Idaho family. Robbie serves as an advocate for anyone looking for a supportive and safe space to learn and grow with others.  The SBG Idaho Tribe has been an incredibly positive force for Robbie and he strives to pay their support forward.

HOLLY LEWIS

[Fitness / Strength & Conditioning]

I was introduced to Brazilian Jiu-Jitsu in 2016 at SBG Idaho. It was pretty special to have two female coaches starting out in the world of Jiu Jitsu with Coach Veta & Coach Shino, thank you ladies! The strong community at SBG inspired me and made me want to contribute to helping others. I have been a lifelong athlete, with my fitness journey beginning with Richard Simons VHS tapes in my grandmother's den and Billy Blanks' Tae Bo Videos at my mama's house. This eventually grew into certifications through Suples®, Yoga for BJJ®, and TRX®. These are only a few I’ve implemented into my own training and coaching for members of all ages and backgrounds. I am currently a blue belt in BJJ and the Head Coach of Strength & Conditioning here at SBG Idaho. I am endlessly inspired by the potential of human performance. My work is dedicated to empowering others with practices and insights to move freely, recover well, and live courageously! I am reenergized by my family, nature, and food. Backpacking through the Sawtooths, paddling in the rivers and lakes, snowboarding/tubing down the mountains and enjoying nourishing food is where you'll find me if I'm not in the gym. I love training for many reasons; from the mental and physical challenges and breakthroughs to the individual and team efforts. I look forward to training with you. Trust the process and enjoy the journey.

Stephen Stirewalt

Stephen Stirewalt

[Boxing]

Stephen began his martial arts journey at the young age of 5, when his parents enrolled him at the Karate Tech school in Ramstein, Germany, as a means of general self defense. Being part of a military family, he never had the chance to stick with any one particular school for long, but continued to train and compete in more traditional forms of martial arts (i.e. Karate, Kajukenbo, etc.) for a good chunk of his young life all over the world! In June 2012, upon graduating high school in Mountain Home, Idaho, and having followed the UFC and the sport of MMA a number of years, decided it was something he wanted to try. After researching gyms in the nearby city of Boise, he decided to begin his MMA journey at Combat Fitness (now known as SBG Idaho)! 5 months later, in November 2012, Stephen had his first Kickboxing bout and won by split decision. He has been hooked ever since! Stephen currently holds the rank of Brown Belt in Jiu-Jitsu, fights professionally in MMA (Pro debut May 2018), and teaches the foundations boxing class in the evenings.

Rebecca Rogers

[Muay Thai / Boxing]

Rebecca Rogers has been training martial arts since 2015. She first started with a cardio kickboxing class that really began to pique her interest in Muay Thai. She found the cardio bag class to be a fun way to work out, however, she soon desired more technical training. This prompted her to reach out to SBG Idaho, where she began training Muay Thai and fell in love with the art. She then began boxing, and is now dedicating a substantial amount of her time to training Brazilian Jiu Jitsu. Rebecca has also recently transitioned into coaching, where she assists Foundations Muay Thai and boxing classes, and has been thoroughly enjoying it. She loves sharing her knowledge with others who bravely choose to step out of their comfort zone and try something new. When Rebecca's not in the gym training, you'll find her in a coffee shop drinking an Americano or at home in her small makeshift studio designing jewelry.

Jo Guinness

[Muay Thai / Boxing]

Born and raised in Columbia, South Carolina, Jo Guinness is no stranger to fighting. A veteran of the underground punk scene and a retired officer in a motorcycle club, violence became routine. After witnessing the murder of his best friend, the stress, frustration, and anger would eventually become crippling. Moving to St Louis shortly after, a change became inevitable and necessary. Jo decided that he needed an outlet and found himself signing up at the local boxing club. While boxing, Jo would also begin training Muay Thai and Brazilian Jiu Jitsu; earning his blue belt from Royler Gracie. After years in Missouri, Jo would relocate to Virginia where he would continue his Muay Thai and Jiu Jitsu training. While training out of The House of Muay Thai in Norfolk, VA and competing in over 20 unsanctioned amateur fights, Jo was booked to compete on a national level in 2020, but COVID-19 cancelled the event. Jo has assisted both as a coach and a training partner in training camps for UFC, Bellator, LFA, IKF, WKA, and Invicta competitors and champions. Jo now finds himself in the Gem State with his wife, Marina and son, Oliver, and is thrilled to show the world that Straight Blast Gym has more than just incredible jiu jitsu.

Brian Robertson

[Kid's MMA / Kid's Brazilian Jiu-Jitsu]

My martial arts journey began with junior high and high school wrestling. About 10 years ago I began training at SBG Idaho after enrolling my son in their youth martial arts program. At the time, my focus was mainly on boxing and Muay Thai as a means to get back in shape and have a shared activity with my son. I promptly lost 20 lbs in my first two weeks! After a year of training I switched my focus to BJJ and MMA. I immediately fell in love with BJJ and wanted to spend as much time on the mats as possible. As I moved my way up the ladder at work, the additional freedom allowed me to spend even more time training, and I eventually earned my BJJ Blue Belt. I also now have two children enrolled in Kids BJJ and MMA. I started coaching by volunteering to help out with kids classes. Having some experience with coaching kids wrestling when I was in high school was helpful. After a couple months of volunteering, I realized I was passionate about working with kids. The fact that I got to share the mat with my own children while watching them learn and grow was a huge bonus! Coach Veta suggested I take the SBG Coaches Course, which ended up being one of the best decisions of my adult life. I find coaching incredibly rewarding and look forward to it every week!

Christina Schraer

[Fitness / Strength & Conditioning]

I have always been passionate about fitness, so when we moved to Boise a few years ago, we decided to check out SBG and loved it! I had never done anything like Muay Thai or BJJ, so it was all new to me, and I was excited to learn more. Of course, with those classes I started doing Strength and Conditioning, and was immediately drawn to that class (even more than the others). Suples is such a cool and unique way to train, and even after years of doing it, there is always something new to learn! I can honestly say I look forward to participating in and coaching SBG's strength and conditioning classes every day. I am a Certified Personal Trainer through the National Academy of Sports Medicine, and I love that I get to help teach people new ways to get stronger. I love getting to see people's excitement as they start to see progress in their skills, strength, and even feel a boost in their self-confidence!

I began my professional mixed martial arts career in 2010 and look forward to fighting until my body crumbles! I love coaching because I want to leave behind a legacy. I want to help change the perception around martial arts and combat sports and help other’s see how much it can positively impact their own lives. Coaching is one of my life’s biggest passions, and I want to share my knowledge and help our students gain physical and mental strength.
