Your fitness plan shouldn’t look like everyone else’s.
Your goals, experience, schedule, injuries, strengths, and Alaskan lifestyle are different. Your coaching should be too.
Programs Built Around You
Every exercise, tempo, and weight is chosen based on your movement assessment, injury history, and current energy levels.
Realistic Nutrition Support
No rigid, joyless food charts. Learn to eat whole foods and satisfy hunger while maintaining energy for family and work.
Progress Beyond the Scale
Track stamina, joint mobility, lifting numbers, sleep quality, and daily confidence—not just a fluctuating bathroom scale.
Coaching That Changes As You Do
Whether recovering from an injury, managing hormonal changes, or traveling, your plan adjusts dynamically with your life.
Three ways we can work together.
Whether you prefer private hands-on instruction in our Homer studio, flexible online coaching via our app, or standalone nutrition guidance.

Hi, I’m Heidi.
I’m a lifelong Alaskan, a wife of 27 years, and a mom of two. I know firsthand what it looks like to balance family, work, seasonal changes, stress, and caring for your health without turning fitness into a grueling second full-time job.
My own relationship with food and fitness wasn't always smooth. As a young competitive figure skater, I lived through the pressure of strict weight standards, restrictive dieting, and secretive binge-eating. It took years of study and unlearning to discover that real health is never about punishment or shrinking yourself.
I started coaching back in 2006 with "Heidi’s Booty Camp" and built Changing Tides around a simple truth: fitness should give you more life, not take your life away. I coach clients through injuries, menopause, hormonal shifts, and busy work weeks because our bodies deserve smart, compassionate, and enduring strength.

Words from people who train with Heidi.
No stock fitness models or fabricated reviews. Real voices from clients and medical practitioners on the Kenai Peninsula.
“I wholeheartedly endorse Heidi Cox as an extremely talented, and superbly educated, expert in personal fitness and coaching. She has a deep understanding of how the body works, and the real mechanics of facilitating personal, positive lifestyle changes. Those traits alone would make her a good investment. She is also a very effective communicator, demonstrates terrific integrity and is super positive. The way she approaches her work dovetails perfectly with the best practices and principles of functional medicine. My patients achieve optimal health much more quickly, and with fewer unnecessary detours, with a top-notch trainer like Heidi.”
“Heidi is incredible. She’s been where I have been physically. She’s not only a health coach but a friend. I love that she pushes me when I need it and also lets me whirl as well! I’m so thankful for the time I have with her! Plus, I know if I want a Reese’s—she’s there to talk to me and sort “why” I need it. Thanks Heidi!”
“With Heidi, you get what you give. If you give her your honesty about your goals, she’ll give you what you want and need, and a little more. Heidi was my weight loss and fitness trainer seven years ago. Heidi was more than a trainer to me though; she was also my therapist, nutritionist and cheerleader! She knew when to push me physically when I didn’t think I could. She thinks about the whole person; all their needs, strengths and weaknesses, and does a great job to give them the results they work to achieve.”
