Hand grips are small, spring-loaded devices you squeeze repeatedly to strengthen the muscles in your hands, wrists, and forearms. They’re one of the simplest pieces of exercise equipment available, but their benefits extend well beyond building a stronger handshake. Regular grip training improves sports performance, supports everyday functional strength, and is linked to measurable cardiovascular health benefits.
Muscles That Hand Grips Work
Squeezing a hand grip activates two groups of muscles. The first is a set of about 19 small muscles located within the hand itself, responsible for the fine control and force you generate when closing your fingers. The second, and more powerful, group sits in the forearm. These larger muscles connect to your fingers through long tendons that cross the wrist, and they produce most of the squeezing force. Because muscle size is closely tied to force output, building up these forearm muscles is what makes the biggest difference in raw grip strength.
This is why people who train with hand grips regularly develop noticeably thicker forearms. The device looks like it only works the hand, but the real engine is in the forearm.
Three Types of Grip Strength
Not all grip demands are the same, and hand grips primarily target one of three distinct types:
- Crushing grip: The ability to close your fingers forcefully around an object. This is what hand grippers train directly. Think of squeezing a tennis ball or giving a firm handshake.
- Pinch grip: Holding something between your thumb and fingers without wrapping your hand around it, like carrying a heavy book by its cover. Plate pinches and pinch blocks target this.
- Support grip: Holding onto a heavy load for an extended time without your hands opening. Dead hangs from a pull-up bar and farmer’s walks build this type.
Hand grips are best suited for crushing grip, though they do carry over somewhat to the other types since many of the same muscles are involved.
Why Grip Strength Matters for Health
Grip strength has become one of the most studied biomarkers in health research, and the findings are striking. A large meta-analysis of prospective studies found that people with the weakest grip strength had a 41% higher risk of dying from any cause compared to those with the strongest grip. For cardiovascular disease specifically, that gap widened to 63%. Every 5-kilogram decrease in grip strength was associated with a 16% increase in all-cause mortality and a 21% increase in cardiovascular disease risk.
Grip strength isn’t causing these outcomes directly. It serves as a window into your overall muscle mass, physical activity level, and metabolic health. But it’s a remarkably reliable one, and it’s easy to measure. Clinicians increasingly use it as a quick screening tool for general vitality, especially in older adults.
Blood Pressure Benefits
One of the more surprising uses of hand grips is lowering blood pressure. Isometric handgrip training, where you squeeze at moderate effort and hold for a sustained period, has been shown in multiple meta-analyses to reduce systolic blood pressure by more than 6 points and diastolic by more than 4 points. A typical protocol involves three sessions per week for eight weeks, using one hand at a time.
A randomized controlled trial published in the Journal of the American Heart Association tested this in patients with peripheral artery disease and found a significant reduction in diastolic blood pressure after eight weeks of training. The effect is modest compared to medication, but for people with mildly elevated blood pressure, it’s a meaningful and drug-free intervention.
Average Grip Strength by Age and Sex
If you’re curious where you stand, normative data from community-based studies give a useful benchmark. For healthy adults measured by dynamometer, average right-hand grip strength in kilograms looks like this:
Men
- Ages 20 to 49: 45 to 47 kg (99 to 104 lbs)
- Ages 50 to 59: 45 kg (99 lbs)
- Ages 60 to 69: 40 kg (88 lbs)
- Ages 70+: 33 kg (73 lbs)
Women
- Ages 20 to 49: 29 to 31 kg (64 to 68 lbs)
- Ages 50 to 59: 28 kg (62 lbs)
- Ages 60 to 69: 24 kg (53 lbs)
- Ages 70+: 20 kg (44 lbs)
Grip strength peaks in your 20s and 30s and holds relatively steady through your 40s before declining. The drop accelerates after 60, which is one reason maintaining grip training becomes more important with age. You can test your own grip strength at most physical therapy clinics using a handheld dynamometer.
Sports and Everyday Performance
Strong hands are a limiting factor in a surprising number of activities. In rock climbing, finger, hand, and wrist strength are essential for holding onto surfaces and maintaining control. Stronger grip also reduces injury risk in the hand, wrist, and elbow during climbing. In grappling sports like judo and Brazilian jiu-jitsu, the ability to maintain a hold on your opponent’s clothing or limbs often determines who controls the exchange.
In the weight room, grip is frequently the first thing to fail during deadlifts, rows, pull-ups, and farmer’s carries. Your back and legs may have plenty of strength left, but if your hands open, the set is over. Training with hand grips between gym sessions can push that ceiling higher. Outside the gym, better grip strength makes carrying groceries, opening jars, working with tools, and doing yard work noticeably easier, especially as you age.
When Hand Grips Can Cause Problems
Hand grips aren’t appropriate for everyone. If you have carpal tunnel syndrome, squeezing exercises can actually make things worse by increasing pressure inside the carpal tunnel, the narrow passageway in the wrist where the median nerve runs. For carpal tunnel, nerve gliding exercises that gently bend and straighten the fingers without moving the wrist are a better choice. These help pump fluid out of the tunnel and relieve pressure on the nerve.
People with existing tendon inflammation in the wrist or elbow should also approach grip training cautiously. Starting with a gripper that’s too stiff, or training every day without rest, can aggravate these conditions. If you feel sharp or burning pain in your wrist, hand, or inner elbow during or after training, back off and let the tissues recover before trying again with a lighter resistance.
How to Train With Hand Grips
For general strength, start with a gripper that lets you complete 10 to 15 full squeezes with moderate effort. Do two to three sets per hand, with about a minute of rest between sets, three to four times per week. Your forearm muscles recover faster than larger muscle groups, so they can tolerate more frequent training, but daily sessions without rest days can lead to overuse.
For the blood pressure benefits of isometric training, the approach is different. Instead of pumping out quick reps, you squeeze at about 30% of your maximum effort and hold for two minutes, rest for a few minutes, then repeat. Four rounds per session, three sessions per week, is the protocol most commonly studied.
Progression is straightforward. When your current gripper starts feeling easy for 15 or more reps, move up to the next resistance level. Most adjustable grippers range from about 20 to 150 pounds of resistance, so there’s room to grow for years. For athletes who want grip endurance rather than peak strength, higher reps (20 to 30 per set) with a lighter gripper are more effective than grinding out a few reps on a heavy one.
