    Mario exceeded my expectations of what I would achieve from working out with a personal trainer. He not only did what was expected in getting me into the best shape I've ever been in my life, but provided invaluable advice and help with nutrition, lifestyle practices, and self-motivation. He helped turn me into not only a prepared college athlete, but also a prepared college student. Staying consistent with Mario's workouts will not only help you achieve your benchmarks, but greatly exceed them as well. Give him a try you won't regret it!!

    I’m not much into Reggae, but the other day I watched a documentary on Bob Marley and what it means to be Rastafarian. The whole concept is about keeping your BODY and MIND strong at all times, an all around FIT mentality. THAT is what Mario Marshall does to assist and better my life. No matter what mood I am in or what has happened before I walked in the door, Mario somehow CHALLENGES me physically, mentally, and emotionally in the gym and somehow ENCOURAGES me to do things I never thought I was capable of doing! Working out is the only weakness in my life and he helps me overcome it and FINISH! The follow through mentality then carries me over into the workplace and he continues to make sure I’m on task throughout the week. Being an athlete himself, he understand the obstacles and does not only sympathize, but empathize. And he is a pretty cool guy! This is in no way robot trainer, Mario is very real and if you are real about maintaining and incredible lifestyle...then he’s your guy!

    I've been an athlete since I was 13 years old, and began weight training soon thereafter. I began training with Mario in 2007 when I was 21. Within a matter of months I was in the best shape of my life. I have not found any other trainer that can constructively train, while having a complete understanding of how to gauge a regimen for any body size. I'm completely happy in training with him now and know that my goals will be met as he has great foresight into how to achieve the results your looking for. Could not recommend more! Call him NOW!

    Thank you for the comment and recommendation Jason. You are the definition of motivation, dedication & determination. Every level I have tested you with, you have not only met it but surpassed it. I can not wait until we reach the next level. You give me drive to be a better trainer everyday. Remember, "The only way out, is through!"

    Mario has transformed my daughter (9) from an ordinary YMCA swimmer into a skilled technical swimmer ready to join a Team USA swim team. Her audition is Friday and we are very excited. Mario's workout habits and attention to detail are a great role model to us all. I would highly recommend him for all children wanting to get to the next level. Good luck in the Olympic trials Mario.

    I'd like to personally encourage anyone who's on the fence with exercise DVDs or with choosing a real trainer to join Mario's team. He's someone that will consult with you on a curriculum that’s meant for you....and that works! No mumbo-jumbo.

    I'm a former pro athlete with 2 kids, clearly with my best days behind me. But when I need that jump start to my physical goals - Mario's my guy!

    Response by Mario Marshall on Oct 22, 2012

    Bernard, thank you for the comment. It's always a treat to train a pro! You truly are a person of great drive. You put everything into what you do and don't mess around. I'm proud to call you a REAL TRAINING client. You have a beautiful family and your kids are very blessed to have such a great role model. Remember, the only way to be number one, is to be number one!
