Matthew AddisonOne SYNCCYCLING class and Matty was hooked. Growing up as a non-athlete, Matty spent his summers indoors watching daytime talk shows and old movie musicals, eventually finding his passion for performing and television. He became a professional performer, toured in musicals and plays, trained in dance, and did television work for several years before deciding to take a break for school. While touring, he saw arts enrichment for youth lacking in many areas and school districts, so he started a business designed to provide theatre and physical fitness workshops/summer camps to children of all socio-economic backgrounds. Performing and dancing helped him discover a love for cardio/aerobic exercise, which sparked in him a newfound understanding of the disciplines of the mind, body and diet. Currently, Matty has his own freelance graphic design business, and you can catch him on-air during pledge drives on our statewide public television station, UNC-TV. Matty is TYRO Certified, CPR/AED Certified and a Licensed Zumba® Instructor. He lives in Chapel Hill with his partner (and fellow SYNCCYCLING Instructor) Kyle. |

Kim GranthamAn active and athletic kid, Kim spent much of the ‘80s dancing, playing soccer, and cheerleading. She learned a lot during the early fitness boom (yes, even from Jane Fonda), but it was in ‘87 during her freshman year at Duke that she first joined a gym and discovered the motivating magic of group exercise. For much of her adult life, Kim enjoyed lifting and aerobics classes, but she ultimately tired of being a gym rat and left the gym in favor of hiking trails with her two labs. In 2008, however, major life changes sent her back to the gym, yearning for energy, encouragement, strength, and an incredible fitness challenge. She found all of those things in the cycling room. After following her favorite instructor, Christine Wall to SYNCSTUDIO, she received her SYNCCYCLING TYRO Certification in Spring 2011. She is excited to share with others this ever-evolving and empowering workout experience. Her musical tastes are broad and not what you’d expect, so you’ll always be surprised by what turns up on her playlist! When Kim’s not at SYNCSTUDIO, she’s running to keep up with her 17 and 13 year old daughters, Hannah and Drew, and her puppy, Cooper. |
