Why Most Fitness Advice Fails Women Over 40 with Heidi Cox
Season 5 of the Field Notes podcast continues with a thoughtful conversation hosted by Heather Moon, who is stepping into a larger hosting role this season with her signature warmth, curiosity, and whole-person approach to health.
In this episode, Heather sits down with returning guest and Alaska-based personal trainer Heidi Cox to explore what fitness really looks like when it’s aligned with real life, changing hormones, injury recovery, mental health, and sustainable wellness.
Together, they unpack the importance of individualized care, behavior change, movement as medicine, and why true health goes far beyond the number on a scale. From navigating perimenopause and burnout to rebuilding trust with your body after injury, this episode offers an honest, encouraging, and deeply practical conversation about creating strength, resilience, and vitality from the inside out.

Key Takeaways:
• Movement should be viewed as a powerful tool for healing and resilience — not punishment or a checkbox to complete.
• Sustainable fitness starts with individualized care: what works for one person may not work for another, especially during hormonal changes, injury recovery, or periods of burnout.
• Small, consistent habits often create the biggest long-term results. Simple daily movement, hydration, better sleep, and realistic goals matter more than extreme routines.
• Real transformation happens when people connect with their deeper “why” — the emotional reason behind wanting to feel stronger, healthier, or more confident.
• True wellness requires a whole-person approach that supports physical health, mental health, nutrition, stress management, and long-term behavior change together.
Heidi Cox
Personal Trainer, Founder of Changing Tides Fitness
Heidi Cox’s journey into health and fitness was shaped not only by education and experience, but by profound personal transformation. From struggling with secretive binge-eating and restriction in her teenage years to navigating the pressures of maintaining a figure skater’s “ideal” weight, Heidi experienced firsthand the emotional and physical toll that unhealthy habits and unrealistic expectations can create.
In 2019, after reaching a critical low point in her health, Heidi made the decision to reclaim her life. Motivated by a deep desire to show up fully for her children — and recognizing that the life she was living was not the life she was meant to live — she committed to healing from the inside out.
Over the following years, Heidi immersed herself in personal growth through gratitude journaling, mindset work, therapy, whole-food nutrition, and healthier coping strategies. She stepped away from using alcohol as a coping mechanism, rebuilt her relationship with movement and exercise, recertified as a personal trainer, strengthened family relationships, and successfully launched a second training location.
Today, with the support of her coach and community, Heidi continues to embrace growth, challenge herself, and help others do the same. Her coaching philosophy is rooted in compassion, sustainability, and meeting people where they are. Whether someone’s goal is simply getting out of bed, crossing a finish line, or learning how to enjoy balance and joy around food again, Heidi is passionate about helping people redefine success in a way that feels healthy, realistic, and deeply personal.
