Precision Trainer

Sean Marcolus is the owner and main trainer at No Limit Fitness. After high school, Sean chased his love of soccer all the way to Hiram on a scholarship. He was only there for a year after a soccer injury caused him to be unable to play. He came back to Richmond Hill and fell in love with the training world. He began doing shows and getting his training certification. After working as a trainer at another facility, he decided to venture out on his own and No Limit Fitness was born. He is extremely experienced and continues to train for shows. Sean believes that working out isn’t just going to a gym and doing something written down or found on the internet. He believes it is all about focus and determination outside the gym with every daily choice from food to activities. He understands that not everyone and every facility is made the same and makes it his mission to make everyone work to be the best version of themselves.

Elite Trainer

Christie Nix, is an Army wife and busy mom of three. She graduated as a NCAA Division 1 college athlete and earned her Bachelors in Exercise Science and Kinesiology with a minor in Business. Now as a busy mom of 3 and army wife she knows how important it is to find a forever fit, creating those healthy habits that can be maintained on autopilot when life gets hectic. The frustrations of pregnancy weight gain and postpartum caused her to lose sight of taking care of herself and obsess about being a certain size. It took three pregnancies to understand that her body is fit if she trains it to be, regardless of how it looked. It’s always been more than a workout, it’s life expressed through movement, creating more not obsessing about less. Striving for progress and not perfection keeps her motivated and craving more; discovering her inner athlete and helping you do the same. Christie has been featured in Gorgo Women's Fitness Magazine as a cover model and featured trainer. She also challenges her inner athlete by competing in Figure, Fitness, and Powerlifting.
