At one point, touching your toes or climbing a flight of stairs without getting out of breath was considered a quick, but reliable test of overall health. Fitness trainer Peter Embiricos says grip strength may sound like another one of those simple measurements, but this one is supported by decades of scientific research.
Researchers from institutions including the National Institute on Aging, along with numerous large-scale studies published in journals such as The Lancet, grip strength can be an indicator of healthy aging and overall physical function. Peter Embiricos explains what grip strength measures, why researchers value it, and how you can improve it.
Grip strength measures the maximum amount of force your hand and forearm muscles can generate while squeezing an object, most commonly using a handheld device called a dynamometer. Although the test focuses on the hands, researchers have found that it reflects much more than hand strength alone.
“Grip strength gives us a snapshot of overall muscular function,” Embiricos explained. “The muscles responsible for your grip are connected to a much larger system involving your arms, shoulders, core, and nervous system. While it doesn’t measure total body strength by itself, it can provide valuable insight into your overall physical condition.”
Peter Embiricos specializes in training clients returning to fitness. He explained that researchers also believe grip strength reflects how well the muscles, nerves, and brain work together to produce force. Since these systems naturally change with age, illness, and physical inactivity, grip strength has become a practical way for researchers and healthcare professionals to assess physical function in large populations. It is quick, inexpensive, non-invasive, and produces highly consistent results, making it one of the most widely used measurements in health and aging research.
Why Researchers Use It as a Marker of Overall Health
Grip strength has become one of the most widely used measurements in health research because it consistently reflects overall physical function. Studies have linked stronger grip strength with better mobility, greater independence in later life, and lower risks of frailty, cardiovascular disease, and premature death.
“Grip strength doesn’t determine how healthy you are,” Embiricos explained. “It provides a quick snapshot of your overall physical function. When it’s much lower than expected for someone’s age and sex, it can signal that further assessment may be worthwhile.”
Simple, inexpensive, and highly reliable, grip strength is now a standard measurement in aging and health research.
Grip strength naturally declines with age as muscle mass and strength decrease, making it a useful way for researchers to track physical aging. Lower grip strength has been linked to reduced mobility, frailty, and loss of independence.
“Growing older doesn’t automatically mean becoming weak,” Embiricos explained. “Much of the decline people associate with aging is linked to becoming less physically active. Strength training, regular movement, and good nutrition can help preserve muscle and physical function well into later life.”
Research shows that older adults with stronger grip strength are more likely to remain independent, recover better after illness, and maintain a higher quality of life.
Yes. For most people, grip strength improves naturally through regular strength training. Exercises such as deadlifts, pull-ups, rows, farmer’s carries, and heavy dumbbell movements challenge the hands and forearms while building overall strength.
“You don’t need to spend hours using hand grippers,” Embiricos said. “If you’re following a progressive strength training program, your grip will generally improve alongside the rest of your body.”
Sports like rock climbing, tennis, and gymnastics can further develop grip strength, but for most people, consistent full-body resistance training provides all the stimulus needed to build a stronger grip.
Simple Exercises That Naturally Develop Grip Strength
Many of the best grip-strengthening exercises are already part of a balanced strength training program. Deadlifts, farmer’s carries, pull-ups, bent-over rows, dumbbell lunges, and even dead hangs all challenge the hands and forearms while building overall strength.
“People think they need specialized equipment to build a stronger grip,” Embiricos said. “In reality, holding challenging weights with good technique is one of the most effective ways to develop it. As your overall strength improves, your grip will almost always improve too.”
For beginners, gradual progression and consistent training are the keys to long-term results.
Why Grip Strength Shouldn’t Be Viewed in Isolation
Despite the research behind it, grip strength is only one measure of health. It provides valuable insight into physical function, but it cannot measure cardiovascular fitness, balance, nutrition, mental health, medical conditions, or lifestyle.
“Someone can have a strong grip because of their job or sport while neglecting other aspects of their health,” Embiricos said. “Likewise, someone recovering from an injury may have lower grip strength but still be making excellent progress.”
Grip strength is best viewed as one piece of the puzzle. Long-term health depends on consistent exercise, quality nutrition, adequate sleep, and healthy daily habits.
