Expert Instructors
Any fool can make someone tired. The fitness industry is inundated with online/weekend certified trainers who became trainers because they like working out.

Training Methodology
The Altus training methods were developed by our founder while serving in the military as an Army Ranger with 75th Ranger Regiment. John had been a performance coach before joining the Army and during a portion of his 7-year military career, he served as the NCOIC of the Ranger Athlete Warrior program. Our military men and women needed a fitness regime that helped them be versatile in all aspects of fitness or a “Master Generalist.” He developed a progressive training system for developing mental and physical fitness cooperatively for Rangers to develop adaptability, versatility, and capability in unfamiliar environments, situations, and conditions. This was a monumental divergence from a sports specificity paradigm of training that prepares athletes for performing in highly specific, predictable, and controlled environments.
He realized that most people were looking for a basic version of this style of training. They did not want to copy professional athletes because they wanted to be more well-rounded. They did not want to copy other functional training programs because those were too focused on “in-the-gym” fitness and not fit for their day to day lives.
