How Raising Your VO₂ Max Helps Fight Cancer
The Molecular and Physiological Truth Behind Oxygen Efficiency and Cancer Risk
In this breakthrough episode of The New Science of Physical Health, host Shane Stubbs reveals how oxygen efficiency—measured by your VO₂ Max—can be one of the most powerful tools in the fight against cancer.
Forget the idea that VO₂ Max is just for athletes. Shane breaks down the molecular, hormonal, and immune system upgrades that occur when you increase your cardiorespiratory fitness—and how these changes can reduce your cancer risk by up to 70%.
This episode will completely reframe how you think about exercise, fitness, and long-term disease protection.
The Oxygen Efficiency Score that predicts disease risk
How low VO₂ Max signals inflammation, poor immunity, and metabolic dysfunction
Why improving VO₂ Max triggers systemic resilience
How myokines fight chronic inflammation
Reprogramming insulin and IGF-1 to reduce cancer fuel
Antioxidant enzymes and DNA repair via improved oxygen efficiency
Activation of p53: your body’s anti-cancer gene
Enhanced immune surveillance: NK cells, T-cells, and macrophages
Oxygen-rich internal environment = less cancer growth
Fat loss and hormone balance that detoxifies your biology
45% lower cancer risk with high VO₂ Max
55% lower cancer mortality in fit individuals
Up to 70% reduction in recurrence risk after treatment
From a VO₂ Max of 33 to 50—and aiming for 60 by age 60
How targeted high-intensity training reshaped his internal biology
Why VO₂ Max training is his personal cancer prevention plan
How to track VO₂ Max and earn AQ Points
Ideal training zones (Zone 3–5)
Weekly targets for adaptation
Why consistency beats intensity
VO₂ Max isn’t just a fitness number—it’s a biological shield against cancer.
Every point you increase makes your internal environment less friendly to disease—and more resilient to illness, aging, and cellular damage.
Estimate or track your VO₂ Max (smartwatch, software, or test)
Earn 100–150 AQ Points weekly
Train 2–3x per week in Zones 3–5
Focus on oxygen delivery, not calorie burn
Stay consistent—adaptati
Are You A Charlotte?
In 1997, actress Kristin Davis’ life was forever changed when she took on the role of Charlotte York in Sex and the City. As we watched Carrie, Samantha, Miranda and Charlotte navigate relationships in NYC, the show helped push once unacceptable conversation topics out of the shadows and altered the narrative around women and sex. We all saw ourselves in them as they searched for fulfillment in life, sex and friendships. Now, Kristin Davis wants to connect with you, the fans, and share untold stories and all the behind the scenes. Together, with Kristin and special guests, what will begin with Sex and the City will evolve into talks about themes that are still so relevant today. "Are you a Charlotte?" is much more than just rewatching this beloved show, it brings the past and the present together as we talk with heart, humor and of course some optimism.
