Exercise Recovery in Aging: Why Recovery Slows and Evidence-Based Strategies
Recovery from exercise slows significantly with age, affecting how often and how hard older adults can train. This review covers the biological reasons for prolonged recovery, its consequences for muscle preservation, and evidence-based strategies to support faster, more complete recovery.

Grip Strength as a Longevity Biomarker: What It Predicts and How to Maintain It
Grip strength is a validated predictor of all-cause mortality, cardiovascular outcomes, and functional decline. This review covers the evidence base, what thresholds matter, and practical strategies to maintain grip and overall muscular capacity with age.

Intermittent Fasting and Aging: Metabolic Benefits, Muscle Risk, and Evidence Review
Intermittent fasting (IF) protocols — including 16:8 time-restricted eating and 5:2 alternate-day approaches — produce modest metabolic benefits similar to matched caloric restriction. Autophagy induction is mechanistically plausible but not confirmed in humans at the cellular level during typical IF windows. Muscle mass preservation requires attention to protein timing and resistance training.
