Aging doesn’t have to mean slowing down.
In a recent video, hybrid athlete and content creator tackles one of fitness’s most critical questions: how do elite athletes stay fast, strong, and powerful well into their 40s and beyond?
Training alongside five-time Ironman finisher Eric Hinman—who at 45 remains one of the fittest hybrid athletes on the planet—he breaks down five specific training factors that don’t just boost race-day performance, but dramatically extend healthspan and longevity.
The takeaway? What keeps athletes competitive for decades is the same thing that extends lifespan and reduces all-cause mortality.

Speed Work Protects Your Cardiovascular System
VO2 max—the body’s ability to utilize oxygen during intense exercise—is one of the most powerful predictors of cardiovascular health. After age 30, VO2 max declines approximately 10% per decade unless actively maintained.
That decline isn’t just about athletic performance. It’s a direct marker of cardiovascular system integrity and mortality risk.
During their track session, the duo completed 8×1 km repeats with 1-minute rest intervals, aiming to keep each rep within 2-3 seconds of the first. This type of structured speed work—whether track repeats, tempo runs, or threshold intervals—challenges VO2 max in ways easy aerobic training simply cannot.
The key metric I want you guys to remember from this speed session, the big takeaway other than just get your speed work in is VO2 max is your marker.
Zone 2 aerobic work builds endurance base, but speed sessions preserve—and even improve—maximal oxygen uptake. That matters whether racing Hyrox or simply wanting to climb stairs without breathlessness at 65.
Strength Training Isn’t Optional—It’s Survival
Strength might seem like a performance metric reserved for athletes and bodybuilders. Research tells a starkly different story.
A massive study covering over 140,000 people across 17 countries found that for every 5% decrease in grip strength, there was a corresponding 16% increase in all-cause mortality.
Read that again. Losing strength doesn’t just make life harder—it shortens life itself.
There was a study and this is reference this one was over 140,000 people done over 17 different countries. For every 5% decrease in strength, grip strength, there was a 16% increase in all cause mortality.
Their strength session at Squatch Fitness in Austin focused on a brutal complex: 4 front squats + 8 back squats, repeated every 3 minutes for 4 sets. This combination challenges mobility, absolute strength, and strength endurance—all crucial for Hyrox wall balls and sled pushes, but equally vital for maintaining independence and physical resilience decades from now.
Functional movements like reverse lunges (4-5 sets of 6 reps per side) engage stabilizer muscles used throughout daily life. Whether carrying groceries or preventing falls, these movement patterns translate directly to real-world capability.
Power Development Keeps You Explosive
Power—the ability to generate force quickly—declines even faster than raw strength with age. It’s also highly neurological, requiring brain-muscle communication that degrades without use.
Their metcon (metabolic conditioning) workout combined explosive movements with cardiovascular demand:
- 12 push presses at 115 lbs
- 16 lateral burpees over dumbbell
- 16 alternating dumbbell snatches
- Repeated for 5 rounds
This type of training operates in Zone 4 intensity, which simultaneously builds VO2 max while developing explosive power. Plyometric movements and heavy, explosive lifts preserve fast-twitch muscle fibers that otherwise atrophy rapidly with aging.
Maintaining power output isn’t about dunking basketballs at 50. It’s about being able to catch yourself during a stumble or react quickly when a grandchild runs into traffic.
Grip Strength and Muscular Endurance Matter More Than You Think
Grip strength serves as a remarkable proxy for overall body strength and health status. Farmer’s carries—a staple in both Hyrox competition and functional fitness—directly challenge grip while building total-body muscular endurance.
During their session, maintaining heavy loads for extended periods (the Hyrox farmer’s carry standard is roughly 1 minute 20 seconds) tests not just forearm strength but core stability and postural endurance.
As we said, grip strength is a fantastic indicator of strength overall. And they just happen to be part of farmer’s carries.
At-home alternatives include:
- Dead hangs from pull-up bar
- Weighted backpack carries
- Plate pinch holds
- Heavy deadlifts with controlled descent
Nordic curls emerged as a dark horse favorite during their training. Despite being “absolutely brutal,” these eccentric hamstring strengtheners offer massive injury prevention benefits for runners while building posterior chain strength crucial for posture and movement quality.
When I say the Nordic curl could be my new favorite exercise, it is a love-hate relationship. The fact that I’ve been neglecting these is just honestly stupid.
Sleep: The Non-Negotiable Longevity Factor
After discussing speed, strength, power, and endurance, the most important factor isn’t found in any gym.
It’s sleep.
Getting less than 6 hours nightly increases all-cause mortality risk by 12-15%. Drop below 5 hours, and that risk jumps to 25-30%.
Sleep deprivation also accelerates telomere shortening—the protective caps on DNA strands that serve as biological aging markers. Shorter telomeres correlate directly with reduced healthspan and earlier onset of age-related diseases.
The reasons I say this is statistically, we know that if you’re getting less than 6 hours a night, you are increasing your chances of all cause mortality by 12 to 15%.
Beyond longevity metrics, inadequate sleep sabotages training adaptations. Natural growth hormone secretion—critical for muscle repair and recovery—occurs primarily during deep sleep stages. Without sufficient rest, gym sessions become wasted effort.
All the money spent on protein powder and gym memberships means nothing without proper recovery.
Training Hybrid Means Training for Life
What makes hybrid training so powerful isn’t just the combination of strength and endurance. It’s that the same training protocols that create competitive athletes in their 40s are identical to those that extend healthspan and compress morbidity.
Eric Hinman at 45 exemplifies this perfectly—maintaining elite fitness not despite his age, but because he’s consistently trained across all five factors:
- Speed work to preserve VO2 max
- Strength training to prevent muscle loss and maintain metabolic health
- Power development to keep neurological systems sharp
- Muscular endurance for functional capacity
- Recovery prioritization to allow adaptations
This isn’t about inspiring Instagram posts or race medals, though those are nice byproducts. It’s about maintaining the physical capability to fully participate in life—playing with grandchildren, traveling independently, pursuing hobbies without limitation.
Training hybrid, whilst it has unbelievable benefit to our feats that we want to do and hopefully inspire the people around us, ultimately it is to improve our overall health, increase our longevity, increase our health span.
Movement is a gift. Every training session is an investment not just in next month’s race, but in next decade’s quality of life. Whether currently training for Hyrox, a marathon, or simply wanting to age powerfully, these five training factors provide the blueprint.
The choice isn’t between being an athlete or being healthy. For hybrid athletes like Hinman—and increasingly, everyday people embracing this training philosophy—they’re precisely the same thing.
