Client Testimonials

Training with X was a great experience. After only meeting with him once, I knew I wanted to continue working with him. Not only was I pushed to my limit, but I also got to make a great relationship with my trainer. Each day I was pushed with varieties of workouts that focused specifically on my goal of training for Volleyball. The fact that X really shaped my workouts and directed them towards my goals in interesting and difficult ways, made me have confidence in him and in myself. I always left the gym wanting a nap, and for me, thats a sign that I had worked hard. I will definitely continue to go back when I can because X always has new workouts to share with me. With the music, friendly people, and energetic environment the Body By X gym is an unforgettable place to workout in. I would definitely recommend X to any of my friends because I know they will be able to achieve their personal goals in his hands.
