Resistance Training: 2-3×/Week

Muscle mass predicts longevity (Attia, 2023; Lyon, 2023). Strength training builds it. Nothing else does.

Why It Matters

Regular strength training improves muscle, bone density, metabolic health, and lifespan (American Heart Association, 2018; Westcott, 2012). You lose muscle every year after 30. Fight back.

The Protocol

If beginner: Full-body routine, 2 days/week. Bodyweight or light weights. Focus on form.

If experienced: Hit all major muscle groups 2-3×/week. Split or full-body—both work.

Key rules:

  • 48h rest between same muscle groups
  • Progressive overload: add weight or reps every 1-2 weeks
  • Joint pain = reduce load, fix form, or swap the exercise

How To Track

  • Strength gains over 3 months (weight lifted, reps achieved)
  • Consistency: ≥8 sessions/month
  • Functional test: Can you carry heavy things without struggle?
