What is a good grip strength for your age and sex?

What Does This Mean?

Your grip strength percentile tells you how you compare to the adult population of your age and gender. Values in the bottom 5% are flagged as "Very Weak" because research consistently shows low grip strength is associated with:

• Increased all-cause mortality risk (Leong et al., 2015)
• Cardiovascular disease events
• Frailty and functional decline in older adults
• Longer hospital stays after surgery

Strength training — especially grip-specific exercises like farmer's carries, dead hangs, and plate pinches — can improve grip strength at any age.

What the Research Says About Grip Strength

The evidence linking grip strength to health outcomes is among the strongest of any single physical measurement. A landmark 2015 meta-analysis by Leong et al. in The Lancet pooled data from 139,691 adults across 17 countries and found that each 5 kg reduction in grip strength was associated with a 16% higher risk of all-cause mortality and a 17% higher risk of cardiovascular mortality — effects that persisted after adjusting for age, BMI, smoking, and physical activity level.

Beyond mortality, grip strength predicts:

• Cardiovascular disease: A 2020 study confirmed grip strength as an independent predictor of myocardial infarction and stroke.
• Diabetes risk: The 2017 China Kadoorie Biobank study found lower grip strength associated with 27% higher type 2 diabetes risk.
• Functional decline: Grip strength predicts mobility limitations and disability in older adults.
• Post-surgical outcomes: Pre-operative grip strength predicts complication rates after major surgery.

Average Grip Strength by Age and Gender

Based on NHANES 2011-2014 data from approximately 5,000 US adults, grip strength follows a predictable trajectory: it peaks in the late 20s to early 30s, holds relatively steady through the 40s, and then declines at an accelerating rate after 50. The decline is not primarily due to aging itself but to progressive loss of type II (fast-twitch) muscle fibers and reduced physical activity — both of which are modifiable with resistance training.

The male-female gap in grip strength is large — men average roughly 60% higher than women of the same age, driven by greater upper-body lean mass and androgen-mediated differences in muscle fiber composition. But the pattern of age-related decline is similar for both sexes, and the good news is that resistance training can preserve grip strength well into the 70s and 80s. A 70-year-old who has trained consistently may have the grip of a sedentary 50-year-old.

Factors That Affect Grip Strength

Grip strength is not just about hand size or training. Multiple factors influence the number you get:

• Hand dominance: The dominant hand is typically 5-10% stronger. Always test both hands and use the maximum — this is what the NHANES data and most research studies use. A significant asymmetry (more than 10% difference) between hands may indicate a prior injury or neurological issue on the weaker side.
• Time of day: Grip strength follows a circadian pattern, peaking in the late afternoon and being lowest in the early morning. If you are tracking progress over time, measure at the same time of day for consistency.
• Body size: Taller and heavier individuals tend to have higher absolute grip strength, simply because larger bodies have more muscle mass. This is why the raw kg number matters less than your percentile within your age and sex group.
• Occupation: Manual workers (construction, manufacturing, agriculture) typically have 10-15% higher grip strength than sedentary office workers of the same age. The "use it or lose it" principle applies strongly to grip.
• Nutrition: Adequate protein intake (1.2-1.6 g/kg/day) and vitamin D status support muscle maintenance. Low vitamin D (below 50 nmol/L) is associated with reduced grip strength in older adults, independent of physical activity.
• Arthritis and hand conditions: Osteoarthritis, rheumatoid arthritis, carpal tunnel syndrome, and trigger finger can all reduce grip strength by 20-40%. If you have hand pain, measure your unaffected hand for a more accurate baseline.

How to Improve Your Grip Strength

Grip strength responds well to training at any age. The key principles:

• Progressive overload: Like any strength training, grip improves when you systematically increase the demand. Add weight, reps, or hold time every 1-2 weeks.
• Exercise variety: Grip involves three types of strength — crushing (closing the hand), pinching (thumb-to-fingers), and supporting (holding). Farmer's carries and dead hangs build supporting grip. Plate pinches target pinching strength. Hand grippers and barbell holds build crushing strength.
• Frequency: 2-3 dedicated grip sessions per week, ideally at the end of your regular workout (training grip first can compromise your main lifts).
• Indirect training: Heavy compound exercises — deadlifts, rows, pull-ups, and farmer's carries — build grip strength as a secondary effect without requiring dedicated grip work.

How to Measure Your Grip Strength Accurately

1. Use a calibrated hand dynamometer (the Jamar is the clinical standard)
2. Sit with your elbow at 90°, forearm neutral, wrist slightly extended
3. Squeeze as hard as you can for 3-5 seconds
4. Rest 30-60 seconds, repeat 2 more times
5. Use the maximum of 3 trials; test both hands and use the higher value
