Best Outdoor Saunas: What to Know Before You Build (Site Prep, Foundation, and Hardwired 240V)
An outdoor sauna is a building project: site prep, foundation, a 240V circuit, and drainage come first. How to choose an outdoor sauna for your site.
Choose Your Home Sauna Heat System Before You Choose a Brand
Traditional, infrared, hybrid, and portable home saunas solve different problems. Why choosing the heat system before the brand avoids the costliest mistake.
Peter Attia's Framework for Prioritizing Health Interventions — What's High-Impact vs. Optimization
Peter Attia separates foundation interventions (exercise, sleep, nutrition) from optimizations like supplements, judged by effect size and trade-offs.
Blood Pressure and Longevity: What Peter Attia's AMA #48 Gets Right About Measurement
Blood pressure is one of three primary drivers of atherosclerosis — yet most people check it once a year. Attia's AMA #48 rebroadcast makes the case for treating it as a daily metric.
Zone 2 Training: Why Time-Constrained Athletes May Be Better Off Skipping It
Peter Attia reframes Zone 2 as a volume tool, not a metabolic must-do — and the implications for busy people are bigger than expected.
Healthy Aging: Why Exercise Is Non-Negotiable and Protein Is Supporting Cast
New research reframes the protein-first aging model. Exercise is the irreducible core of healthy aging — protein helps, but it doesn't replace what movement does at the cellular level.
Heat Training Boosts Hemoglobin — But Can It Make You Faster?
Heat training reliably raises hemoglobin mass by 2–5%. But 5 of 6 trials find no clear performance payoff in VO₂max or sport results. Here's what the evidence actually shows.
Rapamycin + Exercise: Why the First Real Trial Disappointed
Rapamycin may blunt exercise gains in older adults. Peter Attia: this trial is underpowered—but the HbA1c signal is real.
Your Workout May Train Your Kids Too: Peter Attia's April 2026 Research Roundup
Paternal exercise reprograms sperm microRNAs that improve offspring endurance capacity. Plus: autonomic nervous system imbalance as a unifying theory of aging. Four studies from Attia's April roundup.
Peter Attia's AMA 81: Biological Age Tests, GLP-1s, and What Actually Moves the Needle
AMA 81 covers biological age clocks, GLP-1 receptor agonists, Zone 2 training, and sun exposure — a distillation of what biohacking evidence says is worth acting on in 2026.
The Architecture of Longevity: Backcasting VO2 Max and Strength
A technical breakdown of longevity-focused benchmarks, cognitive protection via metabolic health, and the utility of geroprotective GLP-1 applications.
