I have been a client of GCP for about 3 years and it has been a huge transformation for my wife and me. The focus on healthy eating and fitness is what makes GCP different and leads to long term success. The fun and caring community at GCP is what pulls you in and keeps you coming back.

GCP is the first gym that I have joined where I've seen results. I've lost weight and inches but most importantly gained friends. I always look forward to going and can't wait to return. Keep up the amazing work!

GCP is not just a gym, but a support network filled with people who are now my friends and are constantly supporting one another. Nathan and Trevor are awesome coaches and I can’t even imagine going back to working out on my own. This gym has not only helped me get stronger and more fit, but continues to push me to my limits.

The accountability the coaches give helped me so much along the way. I was constantly emailing them with questions and issues, and they were a huge support throughout the six week challenges and beyond. I know I would not have been as successful if it wasn't for them and the encouragement of the coaches. I have been going in to workout at GCP for years and love that it's such a welcoming and friendly environment. It really feels more like a family than a typical gym. I know they care about me and all of their clients. They know how to push me harder than I could ever do on my own, and I've become much stronger both physically and mentally because of them.
