Introduction: Unraveling the Concept of Functional Aging
Aging - it's an inevitable process. But how we age, especially regarding our physical capabilities, is within our control. As a certified personal trainer, nutrition coach, and functional aging specialist, I've dedicated my career to helping individuals like you navigate this process and maintain your fitness and independence as you age. This journey starts with understanding the concept of functional aging.
Understanding Functional Aging
Functional aging refers to maintaining independence and easily performing day-to-day activities as we age. Essentially, it's about preserving our quality of life (Stenholm, Westerlund, Head, Hyde, Kawachi, Pentti…& Vahtera, 2015).
The Three Pillars of Functional Aging
Three key factors significantly influence our functional aging:
Exercise: A progressive exercise routine focused on one to two primary areas of deficit, including strength, balance, and flexibility exercises, is vital to preserving physical function (Paterson & Warburton, 2010). These deficits can be focused on for "blocks" of training, after which the target adaptation may be modified according to an individual's training progress.
Nutrition: Proper nutrition supports overall health and energy levels, aiding in maintaining independence (Houston, Nicklas, & Zizza, 2009).
Cognitive Health: Mental exercises, social interaction, and stress management techniques can all contribute to maintaining cognitive function and independence (Karp, Paillard, Neuhaus, & Guralnik, 2006).
Practical Strategies for Functional Aging
Adopting practical strategies can support your journey to functional aging. Here are some actionable steps you can take:
Exercise: Opt for a mix of aerobic, strength, balance, and flexibility exercises.
Nutrition: Focus on nutrient-dense foods, stay hydrated, and consider consulting a nutrition coach to optimize your diet.
Cognitive Health: Engage in mental exercises such as puzzles, reading, or learning a new skill. Don’t forget to include relaxation techniques into your routine to manage stress.

About the Author
Hi! I'm Emma Mattison. I’m a certified personal trainer (NASM), certified nutrition coach, Functional Aging Specialist, certified virtual coach, stretch & flexibility coach, pranayama breathwork guide, kettlebell trainer, and full-time holistic movement nerd. I'm also the founder of the Academy of Superior Online Coaching (ASOC)—because, yes, I like to stay busy and yes, I think trainers deserve better education than random PDFs and influencer vibes.
I specialize in functional fitness for adults 40+, especially those managing chronic conditions like fibromyalgia, arthritis, joint replacements, or multiple sclerosis. I believe strength, balance, and movement can be playful and scientific—and I live for making complex topics feel like a conversation, not a textbook.
I genuinely love diving into peer-reviewed research (yes, for fun), and my mission is to turn that science into practical, empowering tools you can actually use—whether you’re a client, a coach, or just curious.
My love for fitness really started with helping my best friend—who I now get to call my husband. He’s the reason my work feels so joyful (and why my YouTube channel, Emma Mattison Fitness, looks as polished as it does!). He edits all my content and is probably working on the next video as you’re reading this. Go give it a like if it’s helpful—we make these together, with real humans in mind. 😊😊
