Certified Strength Coach

Hi, I'm Marilyn. I'm a strength coach, lifelong learner, and the founder of Built to Last. After years in competitive powerlifting and bodybuilding (and getting hurt... a lot) I shifted my focus to what I think actually matters—building bodies that move well, feel good, and stay strong for the long haul. I work with women just like YOU who are ready to train smarter, not just harder, with programming built around movement quality and longevity. I'm based in Georgia with my husband and our cats Max and Ali, and I'm here to help you build a body that lasts :)
