My Story

Hi, I’m Jen Calling—a 48-year-young mother of two, living and thriving in beautiful Newport Beach, CA.

My journey has been anything but linear. I’ve faced injuries, surgeries, hormonal changes, and life’s inevitable ups and downs—all of which have shaped me into the strong, resilient woman I am today. Through it all, I’ve learned to embrace every part of me—flaws and all. My passion is helping other women do the same: to discover their true selves through self-love and fitness.

I recently relocated from Seattle after reconnecting with my college sweetheart more than 20 years later. Love brought me to California, and I couldn’t be happier to call this place home. With its year-round sunshine, warm weather, and endless opportunities for outdoor adventures like water sports, hiking, and swimming, I’ve embraced a lifestyle that fuels my passion for movement, health, and personal growth.

A Lifetime of Fitness & Competition

Fitness has been my foundation since childhood, beginning as a competitive gymnast at just six years old. Over the years, I’ve evolved into an endurance athlete, completing multiple marathons and triathlons—including competing at the Ironman World Championships in Kona, HI. At age 46, I took on an entirely new challenge: competing in my first fitness competition. Now, I’m working towards earning my IFBB Pro Card in the Masters Women’s Division—proof that it’s never too late to chase your goals.

My Mission

To empower women to reclaim their strength, confidence, and vitality through a holistic approach to fitness and wellness. I believe every woman deserves to feel strong, capable, and confident in her own body, regardless of her age, fitness level, or past experiences.

Why I Do What I Do

I’ve been where you are. I know what it feels like to feel disconnected from your body, to struggle with confidence, and to feel like you’ve lost yourself in the chaos of daily life. But I also know what it feels like on the other side – the incredible strength, confidence, and joy that comes from taking care of yourself.

My approach isn’t about quick fixes or extreme transformations. It’s about sustainable change, self compassion, and building a life you love from the inside out. Because when you take care of yourself, you show up better for everyone else in your life too.

Ready to Start Your Journey?

If you’re ready to transform your relationship with fitness, nutrition, and your body, I’m here to guide you every step of the way.
