Tiny Daily Four-Minute Routine Boosts Strength and Balance in Seniors, Penn State Finds

A Penn State College of Medicine study published in PLOS One found that doing four minutes of daily resistance-based strength training (four 30-second exercises with 30 seconds rest) significantly improved strength and balance in adults 65 and older within 12 weeks. Participants used bands and a step (or dumbbells as an alternative), and the program led to more repetitions in chair stands and quicker sit-to-stand transitions, highlighting a time-efficient, functional workout to help maintain independence with aging.
