Chad Letterle

I am a retired firefighter/Fire Chief with 22 years of service. When I was younger, I was introduced to strength training through sports but did not realize the importance until I learned about the health issues facing firefighters. I became a Certified Personal Trainer to help my firefighters, and this sparked my love for the field. I am currently a Pit Coach and also an assistant football coach at Normal Community High School at the JV and Varsity level. I also coach/compete for The Pit Powerlifting Team which is made up of myself and 3 very successful Special Olympics athletes. I started powerlifting at 46 years old, so it is never too late to start your fitness journey.

Tanner Johnson

Hello! My name is Tanner Johnson, I just graduated from ISU's Exercise Science Bachelor's program, and am almost completed with my NASM-CPT Personal Training Certification. I've been interning here at Four Seasons full-time, and am super excited to begin a part time position coaching classes in The PIT and acquiring personal training clients. I also look to complete my spin cycle certification, so hopefully you'll be seeing me around here a lot!

I've been involved in athletics & training my whole life, beginning my coaching career in high school as a volunteer with youth league football. I played football & lacrosse in high school and have been consistently training on my own ever since, experimenting with a variety of training methods. I use a very adaptive style of coaching, molding to how you as the client prefer to be coached. When training with me, your goals, priorities, & preferences will be the main focus of the session programming.

I believe exercise and physical activity to be the solution to many of the modern world's problems. Whether you're trying to combat the effects of a sedentary occupation or searching for a more positive outlook on yourself, I think taking steps to be physically active will put you on pace to do both of those and more. Whatever your fitness aspirations may be, I'm excited you chose to chase them at Four Seasons, and I hope to see you soon!
