Key Longevity Adjustments

1. Preventing Sarcopenia & Frailty

Isometric grip strength and lean skeletal muscle mass serve as reliable biomarkers of biological age. Preserving muscle mass protects against fall-related trauma and supports metabolic insulin sensitivity in older adults.

2. Neuromuscular Health & Metabolic Glucose Disposal

Skeletal muscle is the primary organ for blood glucose clearance. Maintaining muscle tissue through progressive resistance training prevents intramuscular lipid accumulation and mitigates type 2 diabetes risk.

3. Key Resistance Training Principles

  • Compound Movements: Focus on multi-joint exercises (squats, deadlifts, chest press, rows).
  • Protein Intake: Consume 1.6-2.2g of protein per kg of body weight daily for muscle protein synthesis.
  • Progressive Overload: Gradually increase weight or repetitions to continually stimulate muscle tissue.

4. Functional Independence in Late Life

Building a solid foundation of muscle mass and bone density in early and middle adulthood ensures mobility, balance, and independence into your seventies and eighties.
