Smart Fit Method Announces Breakthrough Findings in Age-Reversal Study

The Smart Fit Method has announced promising early findings from a clinical study exploring how a structured fitness, recovery and longevity protocol may influence markers associated with biological aging.

Participants between the ages of 50-70 demonstrated an average predicted healthspan increase of 8.2 years over the eight-week study period. One participant experienced as much as 30 years age reduction. Additionally, VO₂ max, meaning the maximum amount of oxygen your body can utilize during intense physical exertion, increases were associated with a 15–30% reduction in mortality risk.

"This study reinforces a simple but powerful idea: aging is not a fixed process, it is something we can directly influence," said Connor Darnbrough, co-founder of The Smart Fit Method. "By combining efficient, high-quality training with targeted recovery and oxygen therapies, we're seeing real improvements in how people move, think and feel in just weeks."

For participant Vivian Phillips, the results were life-changing. "My life has been changed. Before the study, I was very unhealthy," said Phillips. "In eight weeks, my blood sugar greatly decreased, my heart is much stronger, my blood pressure has gone down significantly and I'm definitely much stronger. At the end of the day, the ASU Team Healthspan program saved my life."

The findings contribute to a growing body of research focused on extending not just lifespan, but healthspan — the number of years a person remains healthy, active, and independent. The study is part of Arizona State University's Team Healthspan initiative, a qualifying effort for the $101 million XPRIZE Healthspan competition, which challenges teams to restore muscle, cognitive and immune function by at least a decade.

The Smart Fit Method was selected as the fitness protocol for the initiative because of its personalized, technology-enabled approach to training and recovery.

The company lent its proprietary AI-driven equipment and training protocols to support the study workouts, allowing researchers to deliver precise, measurable, and individualized exercise interventions throughout the eight-week program. Meanwhile, the hyperbaric and hypoxia sessions involving multibaric chambers were led by Joseph Dituri, associate professor at the University of South Florida and core member of the ASU Team Healthspan research team.

Conducted over eight weeks, the study incorporated:

• Smart Fit Method workouts
• Hyperbaric and hypoxia sessions
• Consistent, scientifically guided supplement protocol recommendations

Smart Fit Method provided its proprietary training technology and protocols, while oxygen-based therapies were overseen by ASU Team Healthspan researchers.

Observed participant improvements included:

• Average predicted healthspan increased by 8.2 years
• VO₂ max increases were associated with a 15–30% reduction in mortality risk
• Significant gains in strength and physical performance metrics, including ARX and OxeFit output, grip strength
• Reduced body fat
• Lower blood pressure
• Lower fasting glucose levels and improved insulin sensitivity
• Enhanced immune system functions
• Improvements in cognitive performance markers
• Increased resting metabolic rate (RMR)

ASU Team Healthspan is a team of dedicated researchers, scientists, and healthcare professionals driven by the mission to revolutionize aging. Their goal is to develop cutting-edge solutions that extend healthspan and enhance quality of life for individuals seeking longevity.

"Our findings support the hypothesis that strategically applied hormetic stressors can improve multiple dimensions of healthspan simultaneously," said Judith Klein-Seetharaman, Professor in ASU's School of Molecular Sciences and College of Health Solutions and Team Healthspan Team Lead. "The same adaptive mechanisms that help us respond to environmental challenges may also contribute to slowing the effects of aging and improving a person's healthspan.”
