A 4-minute routine may dramatically improve strength and mobility after 65

Why brief exercise matters

Strength, balance and mobility can affect whether older adults can stand from a chair, climb stairs and walk comfortably. These abilities also matter for living independently and maintaining quality of life.

Falls are a significant concern: the Centers for Disease Control and Prevention identifies unintentional injuries, including those caused by falls, among leading causes of death for adults aged 65 and older. Yet many older adults believe meaningful fitness gains require long or demanding workouts.

A four-minute routine

The study, published in PLOS One, tested a program called FAST-2. Participants performed chair stands, two-arm rows and stair stepping, each for 30 seconds, followed by 30 seconds of rest.

The 97 participants were randomly assigned to either the exercise program or no intervention. Before the trial, they reported exercising about 18 minutes per week on average, below general recommendations of 150 minutes of moderate activity or 75 minutes of vigorous activity weekly.

Barriers and earlier findings

The researchers’ earlier FAST-1 experiment involved 24 older adults doing 30 seconds of push-ups and squats daily. After six months, participants had improved their ability to perform squats. Lead author Christopher Sciamanna said the new results challenge the idea that exercise must be lengthy to help.
