TJ STEINEBACH - OWNER/HEAD BRAZILIAN JIU-JITSU COACH

TJ Gemini.jpg

I have been wrestling and grappling since 8th grade (20 years). I was a member of the 2021 USA Grappling team and competed with them in Serbia. TJ Steinebach is a seven-time BJJ state champion, national BJJ champion, and a three-time 145 lb MMA champion. He is also a two time USA Grappling Team Member. Currently he is a Brown Belt whose lineage is from Soul Fighters Association. TJ studied under Sal Flores at Pallaton BJJ, who studies under head of association Augusto Mendes, a six-time world champion. Throughout his life, TJ played all the sports, excelling in cross-country, track and football. After a falling-out with his football coach during his freshman year, TJ switched his focus to wrestling, which he had started in 8th grade. He found success in wrestling, winning several competitions culminating in being chosen for the 1st Team All Southern Arizona. After high school, TJ started working in gyms and training at Apex MMA in Tucson. He trained in various other gyms, dabbling in higher level MMA and BJJ competitions which led to TJ winning his first six MMA fights. An injury in 2013 led to a shift in priorities to focus on training BJJ under Sal Flores. After moving out of Arizona, TJ ran the UFC gym in Colorado while training at various gyms in the area before opening his own gym with Dave in 2020. The following year, TJ qualified for the USA Grappling Team and competed with them in Serbia. He is currently training for the UWW World Championships in Spain and the Professional Grappling Federation season 4 tv series in October.

DAVID BANKO - OWNER/HEAD STRENGTH & CONDITIONING COACH

smile david Gemini (1).jpg

I have been involved in sports and fitness since I was 5 years old. Playing sports growing up gave me the passion for fitness and I was able to make it a reality in 2016 when I left his accounting job to pursue a career in fitness. I have been working in gyms, running classes, and training clients in person and online ever since. Now living out my dream of opening my own gym with my friend and business partner, TJ Steinebach. I actively train and compete in Brazilian Jiu-Jitsu. He runs the strength & conditioning programs for our competitive athletes and our recreational fitness clients as well.

WHAT OUR CUSTOMERS ARE SAYING

PROVEN RESULTS

SARAH H. - DENVER, CO

“I just had my first bootcamp workout today and it was amazing! I’ve been super nervous about joining a gym or even going to a class because I am not in the best of shape. But I don’t feel that way here. The owners/trainers are super professional and very motivating. They never let you feel like you’re not good enough. The rest of the people at the class welcomed me in and made me feel like I could be myself. I’m excited to go back and continue my fitness journey.”

ALEJANDRO F. - DENVER, CO

"Before coming to Gemini Fitness I had no knowledge of martial arts/combat sports. I thought I would be intimidated in a new environment like that but the coaches and even people who work out here have been nothing but friendly and helpful. The atmosphere is so positive but the coaches still push you to be better everyday. This is a gym run by genuinely good people who sincerely want to better everyone around them. This gym has got me through the insanity of studying for the bar exam, I can't recommend them enough!"

KYLE K. - DENVER, CO

I started training at Gemini pretty early on when things were coming together for their opening. The school is run mostly by two down to earth guys with pretty extensive knowledge and experience in combat sports and physical training/fitness in general. They offer a variety of classes and services ranging from personal training, weight lifting, striking and jiu jitsu. The owners/trainer are very adaptable to individuals and seem to have the resources to add value to whatever your fitness goals are. For me, I have taken a lot from the Brazilian Jiu Jitsu classes run by coach TJ. The culture here is very positive and the folks who current train here are a great, welcoming group of guys with some serious skills. What I appreciate most is TJ's approach around teaching in principles and concepts as oppose to a narrow range of individual techniques. He's also the kind of guy who is happy to have a life talks and values an environment of positivity and character development. The mat space is also really nice. In general I would recommend Gemini as a great place to check out if you're looking some help/guidance with your fitness goals or have an interest in trying jiu jitsu or striking. I have had experience's with sleezy, disconnected owners in past gyms and I am relieved that there is a solid fitness/fighting gym in my area where I can trust the integrity of guys running the place. The price is also very competitive for what is offered.

KAYANNA L. - DENVER, CO

“Gemini Fitness and Combat is one of the most welcoming gyms I have been to. I have felt the most apart of a team in the 3 classes I have attended, than I have in any other team sport I’ve been apart of. If you want to learn self defense, get in better shape, or try something out of your comfort zone, this is the place to do it! Everyone there wants to see you grow and the instructors are very knowledgeable. The environment is so supportive and friendly and it does not matter what kind of shape you’re in. Seriously recommend this place!”

ANDREAS A. - DENVER, CO

"I came into Gemini Fitness & Combat on a whim with no experience. It's clear to see that regardless of your experience, whether you're a beginner or competitive athlete, this is a great place to learn, train, and break a sweat. Above all else, the community around this gym is one of education and support. The coaches are there for you, members are eager to help, and the facility makes you want to get after it. I'm excited for what's to come!"
