David Callicott

I am heavily involved in fitness, and I have been for multiple years now. I started training years ago when I trained my brother and my friends. I strive to get my clients to be in the best shape of their lives, but I also want them to have fun while getting there. I believe that fitness should be fun and I recognize that, for people to stay involved in fitness, it has to be fun. I want my clients to feel stronger and feel better and I help them achieve that by using my experience in HIIT training and weight training. I also strive for my clients to be able to move freely in their daily lives by using a wide range of mobility exercises that will allow clients to be able to move much more comfortably.

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!

Nathan Parker

I am someone who has found a passion for fitness after years of inconsistency. I originally became interested in weightlifting at the age of 14 when I was in FS1, but I was inconsistent and had little idea of what I was doing. Now, I have taken on a mix of strength and hypertrophy (muscle gain) training. I train my clients with the intention of helping them achieve their specific goals and utilize calorie tracking to best control their weight, whether it be to gain muscle or lose fat. My goal is to help people create a solid foundation with proper technique and then push them beyond their comfort zones to reach new levels.
