    My name is Art Biglow, and I’m a certified personal trainer (CPT), certified strength training specialist (CSTS), performance enhancement specialist (PES), and pain-free performance specialist (PPSC) who's dedicated to helping increase functionality through movement. Growing up, sports played a huge role in my life. Football, basketball, and wrestling kept me busy through high school, giving me a healthy outlet for my energy and teaching me valuable lessons about sportsmanship, teamwork, and self confidence. I took up boxing in my early 20’s and won a New England Regional Golden Gloves boxing title. I hung up the gloves but my passion for athletics continued to grow. Countless hours in the gym brought me to the realization that I'm happiest when I'm active and challenging myself. The desire to share that happiness with others while making a positive impact in peoples lives is what drove me to become a coach.
