Trainers

  • Jet Fitness was founded by head trainer & boxer, JJ “The Jet” Johnson. What initially began as a side project to help friends get in shape while supporting his boxing career, Justin has evolved Jet Fitness into a full-scale gym with a local and international clientele.

    What makes Jet Fitness unique is the genuine companionship between the trainers and the clients, who are both invested in reaching each other’s goals and overcoming obstacles. In order to achieve a client’s goals, the duty of an elite trainer goes beyond what happens in the gym, it’s about making serious and dramatic lifestyle changes – this is the Jet Fitness mission.

  • Hello! I’m Grace, a certified nutritional coach and a personal trainer here at The Jet. Michigan State University brought me to the area, where I received a Bachelor's Degree in Nutritional Sciences and started bodybuilding as a hobby fresh out of college. This year I was the Michigan Kalamazoo Bikini Champion, and made it to second call-outs at the National North Americans in Pittsburgh.

    Nutrition and fitness isn’t something I just learned by reading books, but by implementing in my lifestyle over six years. I know what it feels like to feel lost, insecure, and frustrated with myself. From not knowing if you're doing a form right, to restrictive and fad dieting, I have done it all. When I prioritized myself in my life, and committed to a coach, I haven’t looked back. Getting a coach changed my life. My goal as a coach, is to provide you with the resources and the environment for you to identify what's holding you back, and for you to start to envision and implement on who you want to become.

  • Hi my name is Antonio Urista I’m a trainer at Jet fitness.

    At a very young age I developed a passion for fitness, from playing basketball to finding a place in boxing. With over 85 amateur fights, I became a professional boxer in 2013 to the present. I am goal driven, and with an extensive knowledge of the art. I enjoy sharing my expertise in the field and helping people reach their fitness goals.

  • Hi, my name is Matt Rogien, I’m a senior at Michigan State University studying at the Broad College of Business. I started weight training in early high school and along the way developed a passion for martial arts. I started boxing about 2 years ago and incorporated many unique training methods into my workouts.

    What fuels my passion is seeing clients, family members, and friends progress physically and mentally. I’m excited to push you to be the best version of yourself inside and outside of the gym.

  • I am super bubbly, personable, and compassionate. I love being a mom to the coolest kid ever. I am the 2023 King of the Jungle national champ. I box for Team Glass and fitness is my absolute passion. I am in complete beast mode when I'm in my fitness element. I also truly enjoy helping others and push others to push themselves past what they think is too much. I love the saying "Pain is Weakness leaving the Body" because as soon as you feel like you've had enough, go harder! That's where the inner dog mentality is built!

  • Hello, I’m Adam Kehr, a personal trainer here at Jet Fitness. I’ve been competing in sports since I can remember, from playing t-ball as a kid to pursing wrestling for almost 10 years now. It began back in 8th grade, where I started lifting weights, and decided to pursue wrestling.

    My pursuit continued through high school, while also playing football and track. While in college, I wrestled competitively. In my junior year(2016), I moved back home and began to train MMA while also attending Ferris State University. I wrestled on the club team taking 6th at nationals. In 2020 I moved to Lansing to pursue my dream of making it to the UFC, joining Murcialago MMA.

    As a personal trainer I look to help my clients reach their goals, not only in the gym but as a person. I hope to impact people lives, make them better, and bring happiness so it can be spread to the next person and generation!
