Four minutes a day—that’s all it took for a group of adults in their 70s to become measurably stronger, steadier, and faster on their feet, according to a new Penn State study that challenges assumptions about how much exercise older adults need.
12 Weeks, Big Gains
Researchers at Penn State College of Medicine recruited 97 seniors with an average age of 74, who were randomly assigned to either follow a daily four-minute strength routine or continue their usual habits.
Before starting, participants reported only about 18 minutes of weekly exercise, well below the recommended 150 minutes of moderate activity or 75 minutes of vigorous activity per week.
The routine, called the FAST-2—short for Functional Activity Strength Training program—consisted of four exercises—push-ups, chair stands, two-arm rows, and stair stepping—each performed for 30 seconds with 30 seconds of rest in between, using resistance bands and a stepper. Participants were encouraged to increase difficulty over time, such as elevating push-ups or raising step height.
After 12 weeks, researchers measured participants’ ability to stand from a chair, balance on one leg, and rise quickly.
Compared to the control group, participants who did the routine could complete 4.2 more chair stands in 30 seconds, hold a one-legged balance for 3.6 seconds longer, and cut their sit-to-stand time by 2.3 seconds.
Notably, participants stuck with it: They completed the exercises on 81 percent of study days, a high adherence rate that researchers say reflects how manageable a short routine can be, even for people who are busy or reluctant to exercise.
Fall Prevention
The risk of falls increases with muscle weakness. Falls are among the leading causes of death among adults over 65, according to the U.S. Centers for Disease Control and Prevention.
“Improved strength allows them to adjust their footing and recover when events such as a stumble or slip occur,” Dr. John Hinson, an orthopedic surgeon and sports medicine physician at Palm Beach Orthopaedic Institute, who was not involved in the study, told The Epoch Times. Strengthening the core and lower body gives seniors a more stable base for daily movement, he said.
Yet fewer than one in five older adults exercises for the recommended two days a week of muscle-strengthening activities, often because routine workouts are perceived as too long, painful, or complicated, experts say.
Common challenges that seniors face when starting resistance exercises include access to equipment, knowledge of appropriate exercises, and “in my specialty of women’s pelvic health, fear of incontinence during exercise,” Danaya Kauwe, founder and physical therapist at Radiant Pelvic Health & Wellness, told The Epoch Times.
The body responds faster than people expect, Sciamanna said.
“The human body is designed to improve very quickly,” Sciamanna said in the press release. “And just a few repetitions of an exercise performed regularly can lead to huge improvements. Exercise is about forward thinking—think about what you want to be able to do and train for it.”
Safety Tips for Getting Started
Seniors should begin with exercises that match their current fitness level and progress gradually over time, Denise Chakoian, Rhode Island-certified fitness trainer and owner of Core Cycle and Fitness LaGree, told The Epoch Times.
They should take safety precautions such as a short warm-up before exercising to help prepare the muscles and joints for movement, she added.
It’s “extremely important,” she said, to use proper form and avoid rushing through repetitions. The workout area should be free of clutter or loose rugs that could cause a fall, and supportive shoes and stable furniture should be used if balance assistance is needed.
“It’s also important to avoid any exercise that causes sharp pain, dizziness, or unusual discomfort,” she added. It’s also essential to stay hydrated and allow time for recovery between sessions, which can also help prevent injuries.
“Exercise is the key to freedom,” Sciamanna said. “Freedom is the ability to do what you want to do, and I would say that if you can’t do what you want to do, you’re not free.”
