The new medicine: Muscle strength
It's not just for bodybuilders. Strength training is critical for all of us.
When it comes to exercise, regular brisk 30-minute walks through your neighborhood are no longer enough. Research shows that strength training is also key to a longer, healthier life. "Strength training in older adults is very important," says Kelly Macauley, a clinical instructor with Harvard-affiliated Massachusetts General Hospital Institute of Health Professions. "It can slow and reverse age-related declines in muscle mass and muscle endurance, which can keep older adults healthier, longer."
