Peak muscle-building decade + habit formation
Training Protocol
This is your highest testosterone/recovery decade. Train hard: 4–5x/week, progressive overload, compound lifts. Push for PRs. Build the muscle base you'll maintain for life. Recovery is fast — use it.
Nutrition Strategy
Protein 1.8–2.2g/kg. Can tolerate higher carbs and more aggressive bulking/cutting cycles. Creatine 5g/day. Learn to cook and meal prep — habits formed now last decades.
The Key Insight
The muscle you build in your 20s is metabolic insurance for your 40s. Don't waste this decade on cardio-only.
