#365 ‒ Training for longevity: A roundtable on building strength, preventing injury, meeting protein needs, guidance for women and youth athletes, and more | Gabrielle Lyon, Mike Boyle, Jeff Cavaliere

What It Covers

Peter Attia hosts strength coaches Mike Boyle, Jeff Cavaliere, and physician Gabrielle Lyon to discuss resistance training for longevity, covering protein requirements, single-leg training versus barbell lifts, injury prevention strategies, training modifications across age groups, and youth sports specialization concerns.

Key Questions Answered

• •Participation gap: Only 5-15% of Americans engage in resistance training despite its unmatched benefits for lifespan and healthspan. Primary barriers include time constraints, lack of awareness about declining physical capacity, and economic limitations preventing gym access or scheduling flexibility around work and family obligations.
• •Protein targets: Minimum 100 grams daily for both men and women regardless of sex, calculated from target body weight not current weight for overweight individuals. Leucine threshold of 2-3 grams per meal drives muscle protein synthesis. Animal sources (eggs, dairy, beef, fish) provide superior amino acid profiles and bioavailable nutrients compared to plant proteins.
• •Single-leg superiority: Unilateral training (split squats, reverse lunges) produces equal or greater strength gains than barbell squats with significantly lower injury risk. Bilateral deficit research shows individuals generate more total force on one leg than two. Reverse lunges with wide stance and slight torso rotation toward front leg optimize loading while protecting knees.
• •Training frequency: Two sessions weekly for 36 minutes of actual lifting, combined with mobility work and dynamic warmup, produces remarkable body composition changes over one year. Progressive overload through weight advancement matters more than volume. Recovery indicators trump arbitrary programming—waking up crippled the next day signals poor coaching, not effective training.
• •Age-specific modifications: Adults over 50 should eliminate barbell back squats and deadlifts due to catastrophic injury risk versus recovery capacity. Goblet squats and sumo deadlifts maintain hip hinge patterns safely. One injury requiring year-long recovery at 55-plus creates devastating setback impossible to fully reverse, making injury prevention the primary training objective.
