Four minutes a day: Short strength routine makes older adults stronger, study finds
In a Penn State study of 97 people aged 65 and over, four brief daily exercises improved leg strength and balance within 12 weeks. Falls were not measured directly.

Just four minutes of strength training a day can measurably improve mobility in older adults, according to a team at Penn State College of Medicine led by Christopher Sciamanna, writing in the journal PLOS One (release dated Oct. 21, 2026). The randomized trial enrolled 97 adults aged 65 and older with limited mobility, with an average age of 74. One group exercised daily for 12 weeks, while the other received no intervention. At the start, participants exercised for only about 18 minutes a week on average.
The program, called FAST-2, consists of four exercises: push-ups, chair stands, two-arm rows with a resistance band and stepping on a stepper. Each exercise lasts 30 seconds, followed by 30 seconds of rest. Easier variations, such as wall push-ups, were offered to beginners. After 12 weeks, the exercisers managed 4.2 more chair stands in 30 seconds, held a single-leg balance 3.6 seconds longer and stood up 2.3 seconds faster, the study found. Participants exercised on 81% of days.
According to the authors, fewer than one in five older adults meet the recommendation of strength training twice a week. "The human body is designed to improve very quickly," Sciamanna said. The study has limits: it measured physical performance, not the number of falls. It also ran for only 12 weeks, so long-term effects are unknown.
