John Alderman

With my training and background, I followed my passion and opened In-N-Out FITNESS in 2014. As a small business owner, I wanted to ensure that the business I started was designed so that it met both key criteria and my high expectations. In-N-Out FITNESS is not a franchise which might be fashioned following another person's vision. Rather, In-N-Out FITNESS is a result of  years of research which includes:

  • acquiring state of the art best products for the fitness center
  • creating a system so that members can be motivated and accountable
  • designing a program appropriate for men and women of all ages and fitness levels
  • ensuring members receive value and strong results when following the program
  • providing nutritional products and programs for members who need to lose weight
  • working with a personal trainer during each and every session

​John has been developing optimal program and rehabilitation designs for 1000’s of clients, over his almost 20 years as a kinetic specialist.


He has a B.S. in Exercise Science from the College of Charleston, as well as holding C.H.E.K institute certifications in Scientific Core Conditioning, Scientific Back Training, and Program Design.


He holds a Black Belt in Shotokan Karate, and has training experience in Jiu-Jitsu, Wing Chung Kung Fu, Muay Thai, Boxing, and Wrestling.

He believes in full body exercises that mimic primal movement patterns designed to create an ideal environment to develop and improve on all aspects of conditioning.


This includes nutrition, speed, strength, injury prevention, endurance, agility, and self-confidence. In addition, he has years of experience conducting Strength and Conditioning classes,


Women’s Self-Defense, and specialized Co-Ed Boot Camps. He is a dynamic and energetic instructor with a passion for helping his
students’ progress.
