I’m Kaysi Marshall

Owner and coach of Kaysi Marshall Fitness (KMF). I was born and raised in the Lake Zurich/Hawthorn Woods area and love being able to build my business and raise my family in the same community I’ve always called home. I’m married to my husband, Brad, and we have two boys, Luke and Austin. When I’m not coaching or working out, you’ll usually find me spending time with my family, outside with our golden retriever Murph, or finding our next adventure.

My own health and fitness journey hasn’t always been easy. I’ve struggled with endometriosis and experienced firsthand the challenges it can bring. Learning to work through those seasons has shaped the way I approach fitness and coaching and has given me an even greater appreciation for feeling strong, capable and confident in my body.

I believe fitness is about so much more than how you look. It’s about building strength, creating confidence, taking care of yourself and developing habits that allow you to live a healthier, happier life—without feeling like you have to be perfect to make progress.

Through KMF, I offer both in-person training and online coaching designed to meet you where you are. Whether we’re training together in the gym or working together virtually, my goal is the same: to give you challenging, purposeful training along with the guidance, accountability and support you need to reach your goals and create lasting change.

I believe the best fitness program is one that fits into your real life. I want my clients to feel supported, challenged and proud of what they’re capable of—and to walk away stronger than when they started, both physically and mentally.

Work hard.
Get stronger.
Build a lifestyle you love.
