I have been training with Marcin Hahaj at GH Training Center for almost 3 years and have no intention of quitting ever! I cannot even express how much it has affected every aspect of my life. My body looks great, My energy level "jumped to the roof" and even though I am 45 years old it feels like i'm 20! Through personally designed workout routine I was able to transform my body and mind. My personal trainer has made me realize that you do not need an extreme makeover or liposuction. The only way to be in good, feel great about your body and be healthy is through proper exercising and diet. Marcin's enthusiasm and commitment to my success gives me a real motivation. His workout sessions are designed personally to each client. Every sessions he questions me about my eating habits. It almost feels like i'm being brainwashed three times a week. He enforces discipline, challenge and innovations into my routine which is a key to every one's success. I highly recommend GH Personal Training Center in Mount Prospect, especially my trainer Marcin Hahaj.
