What the research found
A new Penn State study suggests that just four minutes of daily strength training can significantly improve mobility and physical function in older adults. After 12 weeks, participants showed meaningful gains in balance, leg strength, and their ability to stand up from a chair, all important factors for maintaining independence and reducing fall risk.
Evidence level: Human study. A study in people, but an association isn't proof of cause.
