STRENGTH TRAINING ISN'T OPTIONAL ANYMORE - HERE'S WHY

MOVEMENT & LONGEVITY Why Experts Now Emphasize Resistance Training A shift in exercise science — strength training now stands alongside cardio as essential medicine for healthy aging. THE BIG PICTURE Cardio remains essential for heart health, but experts now recognize that resistance training — practiced two to three times a week — offers its own powerful benefits for metabolic health, body composition, and healthy aging. WHAT THE RESEARCH SHOWS In a large study of roughly 147,000 people, 90 to 119 minutes of resistance training each week was linked to: 13% lower all-cause mortality 19% lower cardiovascular mortality 27% lower neurological disease mortality Source: Zhang et al., British Journal of Sports Medicine (2026) · observational study, n ≈ 147,000 KEY REASONS RESISTANCE TRAINING MATTERS Improves metabolic health Builds muscle, boosts insulin sensitivity, and improves glucose metabolism. Preserves muscle with age Strength and muscle mass decline naturally after 40, especially with inactivity. Supports a longer life Greater muscular strength is consistently linked to a lower risk of early death. Protects bone & function Helps maintain bone density, balance, and the strength daily life depends on. Makes weight loss more effective Helps the body lose fat rather than muscle, and makes results easier to sustain. Cardio is still essential. Aerobic fitness remains one of the strongest predictors of cardiovascular health and longevity — the greatest benefit comes from combining both. REAL-WORLD EXAMPLES 45-Year-Old Man 5'7.5" (171.5 cm) · 196 lb (88.9 kg) BMI ≈ 30.2 (obesity class I) DAILY CALORIES ~1,700–1,900 kcal/day (~1–1.5 lb/wk loss) ZONE 2 HEART RATE ~105–123 bpm (≈60–70% max HR; max≈175) PROTEIN TARGET ~105–135 g/day (≈1.2–1.5 g/kg) 45-Year-Old Woman 5'3" (160 cm) · 135 lb (61.2 kg) BMI ≈ 23.9 (healthy range) DAILY CALORIES ~1,400–1,600 kcal/day (~1–1.5 lb/wk loss) ZONE 2 HEART RATE ~105–123 bpm (max HR ≈ 175) PROTEIN TARGET ~75–90 g/day (≈1.2–1.5 g/kg) Figures assume a moderate activity level and are a general starting point, not a personalized prescription. Please discuss your individual targets with your physician. A PRACTICAL WEEKLY PLAN Resistance Training 2–3× per week — full-body sessions, 35–45 minutes. Zone 2 Cardio 3× per week, 30–45 min — brisk walking, cycling, or elliptical. Daily Movement Walk regularly and reduce prolonged sitting. Optional Intervals 1× per week of higher-intensity work, once well-conditioned. THE KEY TAKEAWAY It isn't strength versus cardio. For long-term metabolic health, body composition, and healthy aging, both are essential. 2–3× resistance · 3× zone 2 cardio · daily movement DR. POOJA AMY SHAH, MD · INTEGRATIVE + MIND-BODY MEDICINE
