In the podcast "The Diary Of A CEO," performance physiologist Prof. Andy Galpin identifies grip strength, VO2max, and muscle mass as particularly insightful, easily measurable longevity markers. All three can be specifically trained – strength training for grip strength/muscle mass, endurance/interval training for VO2max, supported by consistent training stimulus and sufficient recovery.
Grip Strength, VO2max & Muscle Mass: The Longevity Markers According to Prof. Andy Galpin
On the podcast "The Diary Of A CEO" (host Steven Bartlett), Prof. Andy Galpin was a guest – Professor of Kinesiology, Co-Director of the Center for Sport Performance, and performance consultant for elite athletes (including NBA and Olympic athletes). The interview title "The Muscle Growth Doctor" promises impactful insights into muscle building, training, and aging. We contextualize the central statements, which are widely recognized in sports science.
Three simple yet highly insightful markers
Grip Strength: The Underestimated Health Proxy
Grip strength can be measured with a simple hand dynamometer and reliably correlates in large population studies with general muscle strength, functional everyday fitness, and the risk of falls in old age. Important for context: Grip strength is an indicator of overall fitness, not an isolated causal factor – those who train strength regularly generally improve their grip strength as well.
VO2max: The Strongest Single Predictor for Cardiovascular Health
VO2max describes the body's maximum oxygen uptake capacity under exertion and is considered in sports medicine research as one of the strongest available single predictors for cardiovascular health and overall mortality. VO2max can be improved primarily through regular endurance and interval training (incl. HIIT) – pure strength training has only limited effect here.
Muscle Mass: A Reserve for Age and Metabolism
Muscle mass – as already explained in the context of creatine – is not only relevant for strength but also for basal metabolic rate and metabolic health in old age. Progressive overload in strength training is the most reliable lever for building muscle mass and/or maintaining it in old age.
Training Timing: When is Training Most Effective?
A frequently discussed point from the interview: Is evening training a bad idea? The research is more nuanced than the striking title suggests. Athletes tend to perform best at their accustomed, circadian-aligned training time – so evening training is not inherently “bad,” but primarily problematic if it impairs sleep onset or sleep quality in sensitive individuals. Consistency in training timing and sleep routine seems more important than a blanket “don't train in the evening.”
Environmental Factors for Better Sleep
- Room Temperature and CO2 Levels: a cool, well-ventilated bedroom is associated with better sleep quality.
- Regularity: consistent sleep times support the circadian rhythm – relevant for both recovery and the performance markers mentioned.
- Grip strength, VO2max, and muscle mass are considered easily measurable, well-supported longevity markers.
- Grip strength and muscle mass can be improved primarily through strength training with progressive overload.
- VO2max additionally requires endurance or interval training – strength training alone is not enough.
- Training timing is individual: the accustomed, circadian-aligned time seems more important than a blanket “not in the evening.”
- Consistent sleep times and a cool, well-ventilated sleep environment support recovery and performance.

Frequently Asked Questions
Why is grip strength considered a longevity marker?
In large population studies, grip strength correlates with general muscle strength, functional fitness, and the risk of falls in old age. It is easily measurable and is therefore considered a practical proxy marker for overall strength and vitality – not as an independent cause, but as an indicator of overall fitness.
What does VO2max say about my health?
VO2max measures maximal oxygen uptake capacity and is considered one of the strongest single predictors for cardiovascular health and overall mortality in research. A higher VO2max is consistently associated with a lower risk of chronic diseases and can be improved through regular endurance and interval training.
Is evening training really bad?
Not generally – research tends to suggest that athletes perform best at their accustomed, circadian-tuned training time, and that late, intense training can disrupt sleep in some people. If you train in the evening and sleep well, there's no need to change; if you have sleep problems, an earlier time slot is worth a try.
How are muscle mass and creatine supplementation related?
Creatine increases physical performance during high-intensity interval training as part of short-term, intense physical activity. Those who can train harder as a result indirectly support the building or maintenance of muscle mass – one of the central longevity markers mentioned by Prof. Galpin.
Is strength training alone enough to improve these markers?
Strength training primarily improves grip strength and muscle mass; for VO2max, additional endurance or interval training is needed. A balanced training program consisting of both components plus sufficient sleep and recovery covers all three mentioned markers most reliably.
Conclusion
Grip strength, VO2max, and muscle mass are three easily accessible, scientifically well-documented markers for your long-term health – and all three can be specifically trained. A training plan that combines progressive strength training with endurance/interval units and consistently accounts for recovery and sleep covers all three levers. Creatine can serve as a well-researched, supportive supplement – but it replaces neither training nor sleep. For pre-existing conditions or when starting more intense training: seek medical advice beforehand.
