Lifting Fasted?

Depends on session and age.

Light sessions: fine

Zone 2, mobility, easy strength work.

Heavy lifting: eat

20–30g protein 60–90 min before.

Over 40: eat

Fasted heavy sessions cost recovery.

Under 30 + short session

Often fine. Personal experiment.

Post-workout

Protein + carbs within 90 min.

Track

Strength + sleep tell the truth.
