I have know Carlos for some time, he is a superb personal trainer and coach. The cost is very reasonable and he keeps the sessions interesting and and you stay involved. They also provide excellent dietary and supplement advice; it is truly full service training.

Carlos is a great personal trainer. He has helped me accomplish many of my fitness goals by changing programs based on my goals. When I was focusing on building muscle we worked on individual muscle groups and when I signed up for the Tough Mudder he changed the routine to a whole body approach. Carlos is always listening and adapting to your goals and motivating you to accomplish those goals. I worked out with Carlos for nearly 4 years before I had to move and have not been able to find a suitable replacement since I moved. Above all Carlos truly cares about everyone of his clients.
