Think grip strength only matters when opening a stubborn jar or carrying heavy groceries? Think again. Research suggests that how firmly you can squeeze your hand may offer valuable clues about your muscle function, cardiovascular health and how well you're aging. In fact, scientists increasingly recognize grip strength as a useful indicator of overall physical health.
What Is Grip Strength?
Grip strength measures the maximum force your hand and forearm muscles can produce when squeezing an object. While it primarily reflects the strength of your hands and forearms, researchers often use it as a practical indicator of overall muscular strength and physical function.
That's because muscle health involves more than appearance or size. Strong muscles help you perform everyday activities, maintain mobility and remain independent as you age.
Grip strength is particularly useful in research and clinical settings because it's relatively quick, inexpensive and easy to measure.
What the Research Reveals
Scientists have studied the relationship between grip strength and long-term health for years, and the findings are compelling.
A 2022 systematic review and meta-analysis published in Ageing Research Reviews examined 48 studies involving more than 3 million participants. Researchers found that lower grip strength was associated with a higher risk of death from all causes, including cardiovascular disease.
Similarly, a 2023 study published in Frontiers in Nutrition analyzed data from more than 10,000 U.S. adults and found that those with lower grip strength had a significantly higher risk of all-cause and cardiovascular mortality.
Why the connection? Grip strength may reflect broader aspects of physical health, including overall muscle strength and functional capacity. Lower measurements can sometimes accompany age-related muscle loss, inactivity or underlying health conditions.
However, these findings don't mean that improving your grip strength alone will prevent disease or extend your life. The research primarily identifies associations, not proof that a stronger grip directly causes better health outcomes.
Why Grip Strength Matters as You Age
Muscle strength naturally tends to decline with age, especially when regular resistance training isn't part of your routine. Over time, reduced muscle strength can make everyday tasks more difficult, from lifting groceries to climbing stairs or getting up from a chair.
Grip strength is also one of the measurements healthcare professionals may use when evaluating sarcopenia, a condition involving the progressive loss of muscle strength and muscle mass.
A 2025 review published in Bone Research discussed the importance of grip-strength testing as part of screening for sarcopenia. However, grip strength alone cannot diagnose the condition. A comprehensive assessment may also include muscle mass and physical performance measurements.
The takeaway? Maintaining muscular strength throughout adulthood is about more than looking fit. It's about preserving the physical abilities that help you stay active and independent.
How to Test Your Grip Strength
Grip strength is commonly measured using a handheld dynamometer, a device that records how much force you can produce when squeezing its handle.
During a typical test, you'll grip the device as firmly as possible for a few seconds. Measurements may be taken several times with each hand.
Because grip strength varies according to age, sex, body size, medical conditions and testing methods, there isn't one ideal number for everyone. A healthcare or fitness professional can help interpret your results using appropriate reference values.
If you're monitoring your progress, use the same device and testing technique each time for more consistent comparisons.
5 Ways to Improve Your Grip Strength
The good news? Grip strength is trainable, and you don't necessarily need specialized equipment to work on it.
- Farmer's carries: Hold a dumbbell or kettlebell in each hand and walk a short distance while maintaining good posture. Start with manageable weights and gradually increase the challenge.
- Dead hangs: Hang from a secure pull-up bar for as long as you can comfortably maintain your grip. Beginners can keep their feet partially supported.
- Resistance training: Incorporate exercises such as dumbbell rows, deadlifts and other pulling movements that challenge your grip while strengthening larger muscle groups.
- Hand grippers: Use adjustable grip-training devices to strengthen the muscles involved in squeezing. Start with light resistance and increase gradually.
- Plate pinches: Hold a lightweight weight plate between your fingers and thumb for a short period, keeping your wrist straight. Gradually increase the duration or resistance as your grip improves.
A 2025 systematic review and meta-analysis published in the Journal of Clinical Medicine examined 22 randomized controlled trials involving 1,017 healthy adults. Researchers found that hand-focused strength and coordination training improved grip strength and manual dexterity, although limitations in study quality mean additional research is needed.
For broader health benefits, remember to train your entire body. The Centers for Disease Control and Prevention recommends muscle-strengthening activities involving all major muscle groups at least twice per week.
If you experience hand pain, numbness or persistent weakness, consult a healthcare professional before beginning grip-specific exercises.
Stronger Muscles, Healthier Aging
Grip strength may be a small measurement, but it can provide meaningful insight into your physical health. While it isn't a crystal ball for predicting longevity, it offers another reason to prioritize muscular strength as part of a healthy lifestyle.
By combining regular resistance training, balanced nutrition, adequate protein intake and proper recovery, you can help maintain muscle function and stay active through every stage of life.
