Hope Walton

Personal Trainer

I know how overwhelming fitness can feel when you don’t know where to start because I started there too. I’m a former athlete and have been lifting consistently for the past five years. I know what it feels like to start from the beginning, feel overwhelmed, and question if progress is even possible because I’ve been there too. That’s why I love working with people at all stages, especially beginners or those who feel like they’ve “failed” in the past.


At 19 years old, I am currently working towards becoming a firefighter. Helping people is my passion, and fitness is one of the ways I get to do that every day. Whether your goal is to lose weight, gain weight, build muscle, improve definition, or simply move more and feel better, I meet you where you are.


I’m very flexible in my approach and believe there is no one-size-fits-all plan. Every program I build is based on your needs, lifestyle, and goals so it’s realistic, sustainable, and something you can stick to long term.
