and it doesn't have to suck

Hey! I’m Kim

Certified Health and Fitness Coach & Founder of Fit Girl Magic Society

Staying Healthy After 40? YES, It’s Possible

✔ Following rigid diets that suck the joy out of eating

✔ Pushing through workouts that leave them feeling more drained than excited

✔ Feeling guilty because they can’t go as hard as they used to

✔ Thinking that YOU are broken? Spoiler alert: It’s not you—it’s the PUNISHING diet and exercise routine that’s been working against you instead of for you.

I followed all the “rules.” I worked out harder, tightened up my diet, and did everything I was “supposed” to do.

And yet… my body packed on the weight!

Instead of results, I got frustrated.

Instead of feeling strong, I felt exhausted.

Instead of progress, I felt stuck.


I’ve seen too many strong women over 40 busting their butts trying to lose weight

Most Fitness Plans Are Built for 20-Year-Olds. Not Women Juggling Careers, Families & Hormones

Less struggle. MORE ease & flow

Less obsessing. MORE trusting my gut & listening to your body

Less exhaustion. MORE guilt-free girls’ nights
(because wine & laughter are non-negotiable)

Less pressure to be perfect. MORE feeling comfortable with taking smaller steps 

Sustainable, results-driven strategies that fit YOUR life. NOT the other way around.

Sound familiar?

And now?

I see you.
I know what it’s like to feel like you’re doing everything right and still not getting anywhere. Like maybe you’re the problem.

But here’s the truth: it’s not you.

That old-school "you must struggle" approach? Yeah, that’s the real problem—not you. Once I stopped fighting my body and started working with it, everything changed. And now?

That’s exactly what I help women like you do.

No more guessing.

No more extremes.

Just real, sustainable results. On your terms.

A bitter pill to swallow —what worked in our 20s and 30s? 
Yeah… that magic isn’t hitting the same in our 40s. 


Our bodies have changed, our lives have evolved, and yet, the fitness industry still wants us to train and eat, like we did decades ago. Hard pass.

Sigh…

Your step-by-step guide to losing stubborn belly fat with simple, sustainable habits

That’s exactly what I help women like you do.

The reason why most plans fail is because everything is so damn overcomplicated.

Weight loss doesn’t have to be hard. we’ve just been fed a bunch of BS bad advice.

 I LOVE to keep things simple

with my 3 Cs approach:

Connection

More willpower? Nope. That’ll leave you stranded. What you need is a real WHY. The kind that keeps you moving forward even when you don’t wanna. Let’s lock that in… so those goals? Consider them done.

Clarity

If you keep moving the target, how can you ever expect to hit it? First thing we do together? Ditch the guesswork. We’ll get laser-focused on what you actually want and create a plan that fits YOU. No more shooting in the dark or moving targets!

Consistency

Doing less beats the “go big or go home” game every.single.time. Let’s take small, smart steps together. They add up faster than you think.

No starvation. No over-exercising. No confusion.
Just a clear plan that works!

(not even close)

Yes, I lift weights

but I also believe in rest days and enjoying my coffee with sugar and cream.

Yes, I take fitness seriously

but myself? Not so much. Because let’s be real… if you’re not laughing, are you even living? So, while I’ll teach you how to get strong and feel amazing, I’ll also remind you that grace > guilt every time. Let’s have some fun while we crush those goals!

Yes, I’ll challenge you

but I’ll also meet you exactly where you’re at every step of the way.

I’m not your typical health and fitness coach for women over 40

You don’t need another “quick fix” diet. 


You need a plan that works for you, real support and accountability to keep it simple, and results that actually last

Real women. Real life. Real results.

Let's get to work!

I've incorporated all of these healthy habits pretty easily, which shows me that I've always been capable of doing it, but having a place to check-in is the motivation I need. It doesn't feel like sacrifices like other programs I've done because it's taking small steps each day.

You lit a fire in me girl! I am very happy to say that I have lost some inches off my waist and my hips which is a friggin miracle!!!! Lol I put on a pair of my work pants and had a jaw drop moment, which was followed by the running man and Roger Rabbit in my hotel room.

Christine C. 

I learned that if I start my day with protein, vegetables, and good fat, I don't have sugar cravings throughout the day.

I've been meaning to text!  I went out laast night and wore a dress that i haven't worn in a few years

I was't sure is was going to zip and OMG when it did...

Kim Barnes Jefferson Thank you!!! I can't tell you how much freer (sp?) my brain feels already. You are the best!

Mandy M.

Thank you for guiding and teaching me. I am so thrilled to be able to have energy to run around and play with my daughter. A year ago, that was so very hard for me. Thank you so very much for helping me!

Mandy S. 

Oof! In my head my workout looks good and I think to myself, “How is this ever gonna produce results.” It never fails though. Halfway through my second exercise I realize that I underestimated my sadistic coach and by the end of the workout I’m toast. Lol
