Longevity Lifestyle and Fitness Specialist Online Course


This product is an online, self-study course.

By 2030 there will be more people over the age of 65 than those under 18. Our population is changing and while we are living longer lives, with 6 out of every 10 people having a chronic disease, it would seem we are still not living better. For some, this poses concern, a possible health crisis, yet the longevity industry understands that aging is the #1 finding present in all chronic health conditions. By extending lifespan by just one year, research has shown we will improve how well we live, we will save $38 Trillion dollars in healthcare costs in the US alone and we will boost the economy from money spent on leisure and life-giving activities.

This presents a unique opportunity for health, fitness and wellness professionals to gain specialized knowledge and expertise in the field of longevity. People, regardless of how long they live, want to live well and now more than ever, we know how.

This course will cover the hallmarks of aging and the varied treatments, solutions and strategies available to live longer and healthier lives. With a focus on epigenetics and complex systems biology, you will gain a comprehensive understanding of why we age and why we don’t have to be paired with key findings at each stage of life. You will understand how to assess, recommend and support longevity lifestyle solutions including fitness, nutrition, sleep, mindset, stress optimization and wearable technology solutions in clinical, coaching and community-based settings
