Engy › Who's who in longevity › Joel Jamieson
At a glance
- American strength and conditioning coach who became known for training MMA fighters and other professional athletes.
- Founded 8WeeksOut, a platform with articles and courses on conditioning, and wrote the book Ultimate MMA Conditioning.
- Was among the first to make heart rate variability (HRV) accessible to coaches and athletes, with BioForce HRV and later Morpheus, a system that matches training to recovery.
- Writes and talks about building conditioning alongside strength training, how much volume and intensity you need, and the role of mitochondria.
- Appeared on The Ready State in 2026 to talk about HRV, zone 2 training and VO2 max.
- Relevant to longevity because VO2 max and a solid aerobic base are strongly linked to lower mortality risk; his work is about training them deliberately without burning out.
Criticism and nuance
Sells his own HRV measurement system and training programmes through Morpheus, so his advice on tracking and training by HRV is tied to a commercial product.
