Nutritionist Leyla Muedin discusses research showing simple strength tests—grip strength and a five-rep sit-to-stand chair test—predict longevity in older women. In a University at Buffalo study of over 5,000 women ages 63–99 followed for eight years, stronger grip and faster chair-stand times were linked to lower mortality; every additional 7 kg of grip strength corresponded to a 12% reduction in death risk, and faster chair-stands were also associated with improved survival, even after adjusting for activity, cardiovascular fitness, and inflammation. She emphasizes prioritizing muscle-strengthening alongside aerobic exercise and suggests accessible resistance options (weights, bodyweight moves, or household items) with professional guidance as needed. She then cites UK Biobank data linking long-term statin use to declines in grip strength and appendicular lean mass, urging discussion with physicians and added vigilance, especially for those also using GLP-1 drugs that may reduce protein intake and muscle mass.
