Resistance Training: 2-3×/Week

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

Objective

Maintain or build muscle mass through regular resistance training. This is non-negotiable because muscle mass declines ~3-8% per decade after 30, and low muscle mass is associated with higher all-cause mortality (American Heart Association, 2018; Westcott, 2012).

The Protocol

If beginner:

  1. Full-body routine, 2 days/week
  2. Bodyweight or light weights
  3. Focus on form before load

If experienced:

  1. Hit all major muscle groups 2-3×/week
  2. Split or full-body both work
  3. Progressive overload: add weight or reps every 1-2 weeks

Key rules:

  • 48h rest between same muscle groups
  • Joint pain = reduce load, fix form, or swap the exercise
  • Never skip warmup

Cadence

  • Per session: 45-60 min including warmup
  • Weekly: 2-3 sessions minimum
  • Monthly: Review training log and adjust weights
  • Quarterly: Test 1RM or functional benchmarks

Failure Modes

ProblemFix
Skipping sessionsSchedule like meetings; morning slots have higher adherence
Plateau (no strength gains)Deload week, then increase volume or vary exercises
Joint painReduce load, check form, swap exercise; see physio if persistent
No gym accessBodyweight routine or resistance bands; consistency > equipment
Post-workout exhaustionCheck sleep and nutrition; reduce volume temporarily
