Why Your Grip Strength Says a Lot About Your Health
Share
Introduction
Did you know that how strong your hands are can tell a lot about your overall health? Handgrip strength (HGS), measured by squeezing a handgrip device, might seem like a small detail—but research shows it can be a powerful indicator of fitness, body composition, and even disease risk. And the good news? It's quick and easy to test.
What Is Handgrip Strength?
Handgrip strength is the amount of force you can generate with your hands. It’s usually measured using a small device called a hand dynamometer. There are two main ways to look at it:
- Absolute handgrip strength: Total strength of both hands, usually in kilograms.
- Relative handgrip strength: Your grip strength divided by your body weight. This shows how strong you are for your size.
Both versions are useful, but new research shows that relative grip strength may be even more helpful in understanding overall health.
Why Does Grip Strength Matter?
Grip strength isn't just about your hands. It reflects the strength and health of your whole body. Studies show that lower grip strength is linked with:
- Higher body fat
- Lower lean muscle mass
- Poor heart and lung fitness
- Greater risk for conditions like diabetes and metabolic syndrome
On the flip side, people with higher grip strength tend to have healthier bodies and better fitness levels.
What the Research Found
In a study of over 200 young adults, researchers looked at how grip strength matched up with things like muscle mass, fat percentage, blood pressure, and fitness levels. Here’s what they found:
- Absolute grip strength was strongly linked to lean muscle mass and jumping ability.
- Relative grip strength had a strong negative link to body fat, and a positive connection with aerobic fitness and jumping ability.
- People with a relative grip strength above 1.0 (where your grip in kg is more than your body weight in kg) tended to have better overall health.
In simple terms: if you’re strong for your size, you’re likely healthier.
How to Test and Improve Your Grip Strength
You can easily test your grip strength using a hand dynamometer. These are available at many gyms, physiotherapy clinics, or even online. If your relative HGS is below 1.0, it may be a sign to focus on improving strength and reducing excess body fat.
To improve grip strength and overall health:
- Strength train regularly (especially full-body workouts)
- Do handgrip exercises, like squeezing a tennis ball
- Stay active with aerobic activities like walking, jogging, or cycling
- Maintain a healthy body weight through balanced eating and regular movement
Final Thoughts
Grip strength might seem like a small thing, but it can reveal a lot about your health. Relative handgrip strength—how strong you are for your size—is especially useful. A quick test could help you understand where you stand and what you can improve. So next time you shake someone’s hand or open a jar, remember—your grip strength is more than just muscle. It’s a marker of your whole-body health.
