In short:
- Grip strength is a measurable indicator of muscle strength that predicts all-cause mortality and health risks.
- Improving grip strength comes mainly from regular strength training, enough protein and daily movement.
- Even moderate strength training 2–3 times a week strengthens your grip and supports healthy aging.
- Low grip strength is not destiny — you can raise it at any age with targeted exercises.
Grip strength, or hand squeezing strength, has proven to be one of the simplest and most reliable mirrors of whole-body muscle strength. That is exactly why improving grip strength has become an important topic in research on longevity and healthy aging. In this overview, we look at what the science actually shows about the link between grip strength and mortality, and which lifestyle changes can strengthen your grip in practice.
How does improving grip strength affect mortality?
Improving grip strength has drawn attention because low squeezing strength is associated with a higher risk of death, regardless of age and many other factors. In the large international PURE study, every 5 kg drop in grip strength was linked to a roughly 16% higher risk of all-cause mortality (Leong, 2015). An analysis of the UK Biobank, which included half a million participants, similarly found that lower grip strength predicted a higher risk of cardiovascular disease and all-cause mortality (Celis-Morales, 2018).
Why is that? Grip strength reflects overall muscle mass and strength, and, indirectly, a person’s physical reserve. Declining muscle strength is one of the core features of sarcopenia, and the European working group EWGSOP2 recommends grip strength measurement specifically for the initial assessment of sarcopenia (Cruz-Jentoft, 2019). Muscle strength is not only a matter of movement — it is linked to metabolism, bone density and recovery capacity.
If you want to understand why fitness and daily movement matter so much in the first place, it’s worth reading Why I do all this, which explores the broader meaning of lifestyle changes.
What kind of training strengthens your grip most effectively?
The most direct way to raise grip strength is regular strength training. The World Health Organization recommends that adults do muscle-strengthening exercises at least twice a week, covering the body’s major muscle groups (WHO physical activity guidelines). ACSM guidelines support the same principle: 2–3 strength training sessions a week, with each exercise done for multiple sets.
Pulling and holding movements strengthen the grip especially well — deadlifts, pull-ups, carrying heavy weights (farmer’s carry) and hanging from a bar. Specific tools such as a squeeze ball or a hand gripper also help. Gradual progression of the training load is important: a muscle gets stronger when it is given an ever greater challenge over time.
A systematic review showed that muscle strength training was associated with lower all-cause mortality even in people who otherwise did not favor aerobic training (García-Hermoso, 2018). This means strength training is an independent health factor, not just an add-on to endurance training.

Does improving grip strength depend only on training?
No. Training is the foundation, but improving grip strength rests on three pillars: movement, nutrition and recovery. Enough protein is needed to maintain and build muscle — as we age, protein becomes especially important because the body’s muscle protein synthesis declines. EWGSOP2 stresses that the combination of nutrition and physical activity is the foundation of sarcopenia prevention (Cruz-Jentoft, 2019).
Daily activity outside of training counts too: taking the stairs, carrying loads and gardening keep your grip naturally active. Bohannon (2019) describes grip strength as an indispensable biomarker for older adults, one whose decline can be slowed with lifestyle changes (Bohannon, 2019).
Staying motivated and consistent is often harder than the exercises themselves. You can find inspiration in the story Oh, that Ott and in the overview New active lifestyle environment is open, which show how environment and community support change.
How quickly does grip strength improve?
The first changes in strength often come from nervous system adaptation and can show up within a few weeks, although visible muscle mass gain takes longer. Consistency is key: regular training maintains what you have achieved, while breaks quickly send strength back down. Improving grip strength is therefore more of a lasting habit than a one-off project.

Frequently asked questions
What is good grip strength?
Good grip strength depends on age and sex and is measured with a handgrip dynamometer. EWGSOP2 uses low grip strength cut-off points to assess sarcopenia, but in general a stronger grip means a better reserve of muscle strength.
How often should you train your grip?
WHO and ACSM recommend muscle-strengthening exercises at least twice a week. You can train your grip with rows, carries and hold exercises during the same workouts.
Does improving grip strength help older adults too?
Yes. Studies show that muscle strength can be increased at any age, and in older adults it supports mobility, balance and independence. Start with a lighter training load and increase it gradually.
Does low grip strength definitely mean illness?
No. Low grip strength is a risk marker, not a diagnosis. It is a reason to pay attention to muscle strength and, if needed, to consult a healthcare professional.
