Why VO₂ Max, Grip Strength, and Adipose Tissue Health Are the Metrics That Matter
By Erin Phelan
Fitness Industry Council of Canada
Across Canada, a powerful shift is underway — from performance to prevention. As healthcare systems strain under the weight of chronic disease, the fitness sector has a once-in-a-generation opportunity to redefine itself as a cornerstone of health care, not an accessory to it.
Three measurable indicators now dominate the research conversation on longevity and disease prevention: VO₂ max, grip strength, and adipose-tissue health. Each one offers a tangible way to track — and transform — the health trajectory of Canadians.
WEBINAR ALERT
This Thursday, November 6th at 1:00PM EST, we are diving deep into Preventative Healthcare with Dr. Kaitlin Link, co-founder of Benchmark Proactive Health. After spending a decade as an emergency physician, Dr. Link witnessed far too many patients arriving in crisis — with diseases that could have been prevented through earlier intervention. Her mission now is to change that narrative: empowering Canadians to measure, track, and manage the data that drives long-term health before it’s too late.
VO₂ Max: The Longevity Marker We’ve Been Ignoring
VO₂ max, the body’s ability to use oxygen efficiently, is one of the strongest predictors of all-cause mortality. A JAMA Network Open study (2018) found that elite cardiorespiratory fitness is linked to an 80 percent reduction in mortality risk. Even modest improvements — roughly one metabolic equivalent (1 MET) — can lower risk by up to 15 percent.
This means cardio fitness isn’t vanity — it’s vitality. Fitness professionals can use VO₂ testing or sub-max estimations to quantify aerobic health, shifting the conversation from “fat-burning” to lifespan training.
“What gets measured gets managed — and right now, we’re ignoring the data,” says Dr. Link. “We’re waiting for disease to manifest before we take action. Instead, we should be tracking and managing the known predictors of healthspan.”
Grip Strength: A Simple Test, Profound Insights
Grip strength, long used in clinical settings, has become a reliable predictor of future health. Research presented by the Endocrine Society 2025 shows that individuals with higher grip strength experience fewer obesity-related complications, regardless of weight. Low grip strength, meanwhile, correlates with higher cardiovascular risk and early mortality according to a meta-analysis in The Lancet.
Every gym can use this. A hand-grip dynamometer costs less than a treadmill belt, yet provides one of the most accessible “vital signs” in prevention. Strength testing gives members an objective measure of progress — and helps facilities prove their impact.
“Muscle is the organ of longevity — it powers metabolism, protects the brain, and keeps the immune system sharp,” says Dr. Link. “We once thought exercise was optional. Now we know: strength training is preventive medicine, and every rep is an investment in your future health.”
Adipose Tissue: Beyond the Scale
Body fat is more than storage — it’s an active organ that regulates inflammation and metabolism. Research now shows that where fat is stored is more important than how much. Studies in Frontiers in Endocrinology and Lipids in Health and Disease (2025) demonstrate that visceral and intramuscular fat drive inflammation and metabolic dysfunction.
For fitness professionals, this reinforces a critical message: exercise and strength training improve fat quality and metabolic function, not just appearance. By helping members decrease visceral fat and increase lean mass, we can literally influence how their cells behave.
“The body is the most complex system on the planet — and yet, we’re flying blind,” says Dr. Link. “We can navigate airplanes across oceans with precision, but we rarely track the metrics that keep our bodies aloft. Prevention isn’t guesswork; it’s data-driven diligence, day in and day out.”
Benchmarking a Better Future
Dr. Link’s Benchmark Proactive Health centre in Burlington, Ontario, is a model for how fitness and medicine can merge. After a decade in emergency medicine, she built a proactive-health practice that combines VO₂ max testing, DEXA scans to evaluate adipose distribution, grip-strength assessments, and other metrics to create data-driven prevention plans customized for each patient. She sees the fitness industry as essential partners in the mission to extend Canadians’ healthspan.
Her philosophy — “Better Data. Better Insights. Better You.” — perfectly captures the next phase of our industry’s evolution: evidence-based, measurable, and collaborative with healthcare.
From Fitness to Preventive Health
The next decade belongs to those who can quantify health, and the fitness industry is poised to play a powerful role in the health of millions of Canadians. To do this, we must:
- Measure what matters — VO₂ max, strength, composition.
- Educate members that these metrics predict longevity better than BMI.
- Collaborate with medical partners and employers to make prevention the norm.
By reframing fitness as health infrastructure, we’re not just changing bodies — we’re extending lives.

Let’s make Canada stronger — one VO₂ max, one grip test, and one member at a time.
Fitness Industry Council of Canada (FIC) is the not-for profit trade association that represents the voice of fitness facility operators across Canada. Representing more than 6,000 facilities with more than six-million members nationwide, FIC pursues a legislative agenda in the hope of bettering the fitness industry for both consumers and operators. FIC aims to work with both industry and government to improve the health and physical activity levels of Canadians.
