Strength / Hypertrophy Training — Exercise & Movement

Progressive resistance training for muscle mass preservation, metabolic health, and longevity — considered essential by all major longevity researchers.

Overview

Resistance training is considered non-negotiable by virtually every longevity expert (Attia, Huberman, Galpin, Patrick). A 2022 British Journal of Sports Medicine meta-analysis (n=370,000+) found that 30-60 minutes/week of muscle-strengthening activities reduces all-cause mortality by 10-17%, cardiovascular mortality by 17%, and cancer mortality by 12%. Muscle mass declines 3-8% per decade after age 30 (sarcopenia), accelerating after 60. Compound movements (squat, deadlift, bench, overhead press, row) provide the greatest stimulus. Training 3-4x/week with progressive overload is the standard prescription for both hypertrophy and strength.

Indications

  • Sarcopenia prevention and muscle mass preservation
  • All-cause mortality risk reduction
  • Bone density maintenance (osteoporosis prevention)
  • Metabolic rate and glucose disposal improvement
  • Functional independence in aging
  • Hormonal health (testosterone, growth hormone, IGF-1)

Mechanism of Action

Progressive overload creates mechanical tension on muscle fibers, activating mTORC1 pathway for muscle protein synthesis

Dosing

CompoundDoseFrequencyNotes
Hypertrophy Training3-5 sets x 8-12 reps per exercise3-4x/weekRPE 7-9; 60-80% 1RM; each muscle group 2x/week
Strength Training3-5 sets x 3-6 reps per exercise3-4x/weekRPE 8-9; 80-90% 1RM; longer rest periods (3-5 min)

Safety & Contraindications

  • Learn proper form before adding significant load — consider working with a coach
  • Progressive overload should be gradual (5-10% load increase when all target reps achieved)
  • Deload every 4-6 weeks (reduce volume/intensity by 40-60%)
  • Avoid training through joint pain — distinguish from muscle soreness
  • Blood pressure can spike during heavy lifting; Valsalva technique requires training
