New to KJ Fit? Grab Your Free Strong Start Guide
With over 12 years and 15,000 coaching sessions, I know what it takes to get busy people strong, fit, and lean in less time. The work starts in the gym, but the results go way beyond it—into your energy, confidence, and everyday life.
Random workouts, no plan.
Believing “more is better.”
Form and technique need work.
Overcomplicating nutrition or chasing quick fixes.
Not training hard enough.
Prioritizing cardio over strength.
Inconsistent efforts.
All-or-nothing mindset.
But don’t worry...this is where I come in.
Most people think they need to spend hours in the gym 5–6 days a week to see results. They don’t.
I’m Kristin Johnson. Personal trainer, strength coach, and big believer in doing less, better.
My 2x/week, 30-minute sessions are designed for busy people who want real results without living in the gym.
You’ll build strength, improve fitness, and finally feel in control of your progress without extreme programs, endless cardio, or complicated meal rules.
For women looking for deeper change, I also offer coaching that blends strength training with nutrition, mindset, and lifestyle work — helping you break free from all-or-nothing thinking and create lasting results.
Whether your goal is dropping weight, gaining strength, or just feeling good in your own skin, we’ll train smart, stay consistent, and make it fit your life.
The ultimate 12 week transformation for women who've tried everything and are tired of feeling stuck and uncomfortable in their own skin.
Lose the weight, keep it off, and feel like yourself again without starting over every Monday.
What Clients Are Saying
“I was lifting, running, doing spin class, and many other workouts but I didn’t start to see any progress until I met you”
Tara
I have come so so far leveling up my fitness by working with her for less than 6 months. The accountability is something I need. Her knowledge and ability to create well-rounded accessible programs for her clients (from all walks of life) is incredible.
Natalie
Kristin is really gifted at what she does. My life is better for having worked with her.
