Episode notes

ADVICE

Pick One Reliable Body-Composition Method

Use a consistent body-composition method and track relative changes over time.
Scan monthly or every 2–3 months for most people; use DEXA less frequently for bone data.

ADVICE

Pair Strength And Conditioning Intentionally

Combine resistance training with deliberate aerobic work for best recomposition.
Apply resistance consistently, even with sandbags, bands, or vests, if heavy gym access is limited.

INSIGHT

Muscle Is A Metabolic And Endocrine Organ

Muscle acts as a metabolic sink and endocrine organ that improves metabolic regulation.
Healthy, functional muscle matters as much as absolute muscle mass for long-term health.
