Hi, I’m Kristin—a strength & fitness coach specializing in High Intensity Training.

I help real people get strong, lean, and finally feel like themselves again—without living in the gym or obsessing over every bite.

I live in a suburb of Grand Rapids, MI with my three teenagers and two dogs, and I’ve been coaching since 2014.

With 15,000+ sessions under my belt, I’ve worked with pro athletes, busy moms, doctors, social workers, teachers, business owners, and everyday people who are ready to stop starting over and build something that actually lasts.

I DIDN'T GROW UP THINKING I'D BE A PERSONAL TRAINER.

Like a lot of people, my relationship with food, exercise, and my body has been… complicated.

I didn’t grow up dreaming of being a personal trainer.

I just knew I wanted to feel strong.

Fast-forward 10+ years, and here I am—a strength and behavior change coach helping people:

✔️ Stop chasing smaller and start building stronger

✔️ Take up more space, not less

✔️ Keep muscle, ditch diet culture

HOW I GOT HERE

Growing up, I was always moving—swim team, volleyball, softball, Tae Bo with Billy Blanks (you know the vibe).

Then life threw curveballs. I lost myself.

I did what I thought I was supposed to do:

✔️ College, marriage, kids

✔️ Every diet in the book (even the sketchy ones)

✔️ Always feeling like my body was the problem

Truth? I wasn’t just trying to fix my body—I was trying to fix my soul.

Spoiler: That doesn’t work.

ROCK BOTTOM & BREAKING CHAINS

Turns out rock bottom has a basement.

It was dark, but it’s where I started breaking the chains.

I was ending my marriage, burned out at work, and hollow inside.

In a last-ditch effort to make money from home, I joined Beachbody (we don’t talk about it)—but it reconnected me with my inner athlete.

Hiring a personal trainer flipped the switch:

✔️ I stopped training to shrink—I started training to grow
✔️ I fueled for strength instead of punishing with food
✔️ I became someone I respected

And I knew: I wanted to help other people do the same.

BECOMING A COACH

told my coach I wanted to do what he did. He said, “You’ll never pass your cert during a divorce.”

…Yeah, no.

Mid-divorce, I became a certified trainer.

I started in my basement. People thought I was nuts.

But failure wasn’t an option.

By 2016, I moved into a private gym—and I’ve been growing ever since.

MY COACHING STYLE

Big sister energy + strength + strategy + a proper amount of woo ✨

I train anyone who wants to get stronger—men, women, beginners, athletes—but I have a special place in my heart for helping women break free from diet culture and self-doubt.

Most people come to me for “toning” or weight loss.

What they really need?

✔️ Support

✔️ Accountability

✔️ Behavior change

✔️ Permission to want more

That’s why I created Unchained—a 12-week transformation experience for women ready to get out of their own way and feel strong in body, mind, and life.

Because fitness should make you feel better, not worse.

Because you’re not broken—you’re just buried under BS that wasn’t yours to carry.

THINGS I KNOW FOR SURE...

✔️ You don’t need another cookie-cutter diet. You need one that works in real life.

✔️ You don’t need to live at the gym. You need intensity, consistency, and a plan.

✔️ You’re not the problem. The fitness industry profits off your insecurity.

✔️ When you stop fighting your body and start working with it—everything changes..

BEYOND THE GYM...

I’ve got three teens, two dogs, ADHD, a lip gloss obsession, and a love for sparkles + 90s rap (yes, I’ll out-rap you to Hypnotize).

I’ve also:

✔️ Been burned by diet culture
✔️ Rebuilt after injuries
✔️ Made fitness simple enough to actually stick

If you’re tired of starting over—you’re in the right place.

Let’s break the rules. Build the muscle. Take back what diet culture stole.
