Billings MT Gym & Training Facility

Thank you for your interest in GymJay and CoachJay Inc. Gym Jay is a new home for Coach Jay — a functional fitness facility set in a warehouse in the historic Old Town Works corridor on Minnesota Avenue in Billings, MT. The culmination of many years of work, study and experience, GymJay is an overarching concept that strives to help you exercise and educate every area of a healthy body and mind. Coaching services by CoachJay will continue as before. This program is not just for elite athletes or triathletes — we welcome all levels of fitness and anybody at any level of activity. We have assembled an outstanding collection of programs that will lead you to your fitness and performance goals. We have extensively studied the science of developing training programs and classes to produce effective, efficient results. We have purchased the highest quality, most state-of-the-art equipment for you to use to carry out these programs. We have state of the art testing equipment so we quantitatively know: where we are starting from, where we want to go, and the best way to get there.

Our trainers, coaches, and clients are the cornerstone of GymJay; they live what they teach and they love what they do. They are constantly honing their skills and expanding their knowledge. Despite their level of excellence within in their craft, they agree that there is no room for complacency; at GymJay we want to grow with you. We know each member has his or her own unique goals and every member’s goals are equally valid. We understand the commitment you have made to your health and we are equally committed to you. At GymJay you can expect to have fun. You can expect to be pushed, tested, motivated and encouraged. You can expect to learn. You can expect to see results.

Please contact us if you have any questions about GymJay. We look forward to a long and healthy relationship with you.
