Five Evidence-Based Strategies for Maintaining a Healthy Muscular System

1. Regular Physical Activity: ≥150 min/week moderate aerobic + 2 days resistance training; builds mass, strength, flexibility.
2. Balanced Nutrition: Adequate protein (1.2–2.0 g/kg/day), complex carbs, healthy fats, micronutrients (vitamin D, magnesium, potassium).
3. Sufficient Sleep: 7–9 hours; growth hormone and testosterone peak during deep sleep, driving repair.
4. Stress Management: Chronic cortisol elevation promotes catabolism; use mindfulness, therapy, leisure.
5. Hydration: 2–3 L/day water; supports nutrient delivery, waste removal, electrolyte balance.

Consistency across these pillars optimizes muscular health across the lifespan.
