Personal Trainers in Lewiston, ME

Hey, I’m Erin — speaker, author, coach, and personal trainer with a mission to help people build strength from the inside out. I’ve been training clients since 2010, and my approach is all about meeting you where you're at. Every program I create is fully customized to your goals, your schedule, and your life. I stay connected with my clients, making adjustments as needed and being available when support matters most — because real coaching is about more than just workouts. Beyond the gym, I’m also a keynote speaker and author of You Are More Than Your Sport, where I dive into the deeper work of balancing life, mental health, and identity. My coaching goes beyond reps and sets — it’s about building lasting strength, both physically and mentally.
