JJ Johnson “The Jet”

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.

Matt Rogien

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.

Hi, my name is Dylan Young and I am the Muay Thai Instructor at Jet Fitness. I am a student at Michigan State studying advertising and entrepreneurship. Over the past two years, I have developed a love for martial arts, specifically boxing and Muay Thai.

My goal is to push my clients to become the best versions of themselves while also breaking down the importance of the techniques they’re learning. Seeing my clients improve over time is what pushes me to keep improving and striving to be the best version of myself as well.

Aria Kleber

Hi everyone! My name is Aria, I am the front desk associate at Jet Fitness and I do a small amount of PT here at the gym as well. I am the newest member of this Jet Fitness family, working to keep the gym organized and accessible.

A little about me, I am a Senior at Michigan State University studying Criminal Justice and Psychology. I am also the Captain of the MSU Women’s Rugby team, so the sport of boxing is right up my alley. I have started boxing here at Jet Fitness, that is, when I am not behind the desk. If you are looking for a fun way to stay active, this is the way to go! If you have any questions please feel free to give the gym a call and I would love to help.

This is a friendly, motivating, and safe environment to reach your goals. Hope to see you in!

Adam Kehr

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!
