Four-Minute Daily Exercise Boosts Mobility in Older Adults, Study Finds
Penn State researchers tested a four-minute, home-based strength routine (FAST-2) for 12 weeks with 97 sedentary adults aged 65+ and found the exercise group improved chair-stand repetitions, reduced sit–stand time, and extended one‑leg balance, with an 81% workout completion rate. The findings suggest a tiny daily workout can meaningfully enhance mobility and potentially reduce fall risk, though long-term effects and applicability to those with more severe limitations require further study.
