“Strength Training vs. Cardio — Why We Need Both, but Strength Wins for Longevity”
Cardio gets your heart pumping, but strength training builds the muscle and resilience you’ll carry through life. Here’s how they compare—and why strength is so critical for living long and well.
Key Points to Include:
• Cardio (aerobic) exercise is excellent for heart health, lung capacity, and circulation. https://pmc.ncbi.nlm.nih.gov/articles/PMC6304477
• Strength (resistance) training improves muscle mass, strength, bone density, and metabolism. https://pubmed.ncbi.nlm.nih.gov/22777332
• A strong body handles stress, disease, and aging better. Strength training is associated with improved functional independence and lower mortality in studies. https://pmc.ncbi.nlm.nih.gov/articles/PMC6377696
• In older adults, gains in strength and muscle (even modest ones) often translate directly into better balance, fewer falls, more ease in daily tasks. https://pmc.ncbi.nlm.nih.gov/articles/PMC2892859
• That said, cardio is complementary—not a replacement. A balanced fitness program uses both.
Tomorrow: how age changes muscles and how strength training is your defense.
The effectiveness of resistance exercise for strength improvement among aging persons is inconsistent across investigations, and there is a lack of research synthesis for multiple strength outcomes. The systematic review followed the Preferred ...
