Ryan SandersPersonal Trainer
Ryan Sanders
Personal Trainer
Coming from a family background of amateur and professional athletes, Ryan was exposed to fitness at an early age. However, through some very challenging times as a child, he became deconditioned and very overweight. Playing sports in high school was difficult and science and math was his escape from those challenges. He later became a Project Manager in construction after completing his B.S. in Civil Engineering. While in that role, he learned how to apply what he had from assessing and building civil structures to applying it to the human body. For the technical growth, he utilized NSCA’s Certified Strength and Conditioning Specialist certification to grow his professional career in training.

Ryan’s specific goal is to assist you with reducing and eliminating joint pain, improving your strength and cardiovascular abilities and establishing key lifestyle habits to live an abundant life. Ryan lives with his wife Oliana in Denver, where they love camping, snowboarding, martial arts, hiking, fishing and outdoor music concerts.
