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.

  • Fitness has been a big part of my life since starting sports at the age of 3. Not only has it given me a community of like minded people, it paved the way for me to break the state of Michigan’s state record in discus. This led me to pursue higher education and athletics at Texas Tech University. I want to help as many people as I can reach their goals and give them the community and outlet I was lucky enough to experience. Reaching fitness goals gives people an unexplainable confidence in all areas of their life and I love helping people gain that.

  • 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.
