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!

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.

Excellent workout program and very motivating instructors! GCP really cares for the health and fitness of its members, as demonstrated by amazing communication about diet, fitness and on-site body metric evaluations to help gauge personal progress.

This is the best gym ever, it's like having a personal trainer at all times. I'm no athlete, I'm 59 and have several autoimmune diseases but this gym got me moving. Do yourself a favor and check it out. It's the best decision you'll ever make.
