University of Pennsylvania study finds short daily exercise improves elderly strength

A study from the Perelman School of Medicine at the University of Pennsylvania suggests that just four minutes of daily resistance exercise can significantly improve muscle strength, balance, and mobility in adults aged 65 and older.

The research, published in the journal PLOS One, utilized a program called FAST-2. In a study involving 97 volunteers with an average age of 74, participants showed marked physical improvements after 12 weeks. Lead researcher Christopher Sianna noted that the human body is designed to improve quickly, and even a few regular repetitions can lead to substantial gains.

These improvements are critical for maintaining physical autonomy and reducing the risk of falls, which are a major cause of injury and death among the elderly. Despite these benefits, fewer than one in five seniors currently meet the recommendation for strength training at least twice a week, often due to physical discomfort or time constraints.
