We started this for people who still want to train well as they grow older.
We exist because adults aged 35+ deserve a fitness program built specifically for them — not a scaled-down version of something designed for a different body, different goals, and a different stage of life.
"Growing up, I realized very quickly that I come from a family of sport and exercise. Ever since I can remember, my parents had a very active routine and always encouraged us to do the same.
The apple did not fall far from the tree, and I always found a way to get outside and play some form of sport. Over the years I have trained or competed in everything from tennis and rock climbing to horse riding and surfing. Through all of that I also found my life in rugby, a sport I have now played and competed in for the last 20 years, including for the UAE National Team in Asian Championships.
As I grew older, I realized my parents still wanted to stay active but no longer had the right avenue. My dad would restart training, overdo it, and get injured. My mum would sign up for classes or memberships but quickly feel that they were not built for her changing body and interests.
That was when they started asking me the same question their friends were asking too: how do we stay fit at this age? The intent was there, but the right solution was not.
To answer the question, this motivated me to start my personal training journey. I completed the International Sports Sciences Association level 3 personal training certification. Followed by ISSA senior fitness specialization. Most recently, I completed the GMP fitness certified longevity and wellness coaching accreditation.
That is how AETERNUS was born. I researched what gyms, fitness studios, yoga spaces, and different specialists were offering, then focused on education so I could build something genuinely suited to people aged 35+.
The result is the AETERNUS program: a science-led training system designed to help people move better, feel stronger, and age with more confidence, capability, and independence."

Every exercise, every protocol, every rest interval is grounded in peer-reviewed research on human longevity and functional aging. No trends. No shortcuts.
You are not a template. Your programme is built around your health history, goals, lifestyle, and movement patterns — and it evolves as you do.
60 minutes. Twice a week. That is all it takes when the programme is intelligent. We designed AETERNUS around busy, high-achieving adults.
We do not do drop-in classes. AETERNUS is a committed relationship. We track every session, every metric, and celebrate every milestone with you.
Mind, Body, and Heart are not separate. Our sessions integrate breathwork, cognitive stimulation, strength, mobility, and cardiovascular health in every session.
Bi-annual health assessments, movement screenings, and progress tracking mean you always know exactly how far you have come — and where you are heading.
