  • Great workout!!! And excellent trainers. I have tried many gyms over the years and at one point in time I was even a trainer myself. Alex and his staff are very knowledgeable and can customize the workout to fit my needs and ultimate goals. The training routine is very accommodating for all of us with a busy work schedule, and family obligations. It is definitely worth it!!! 10 out of 10 Cheers!!!
