Generally speaking, the grip strength of 40-year-old men is 43 ~ 50kg, and that of women is 27 ~ 3 1kg.

Grip strength body mass index = grip strength/weight * 100 (the first two units are kilograms) Grip strength index mainly reflects the strength of human forearm and hand muscles, and is also related to the strength of other muscle groups, and is also a good indicator to reflect the overall strength of muscles.

If the grip strength is found to be decreased, it is necessary to consider whether the heart function is decreased or there is systemic arteriosclerosis. It is recommended to go to the hospital's cardiology department for an examination.

Extended data

Practice method of grip strength:

Pull: Every pull starts with the grip, so basically every rowing, pull-ups or hand-loading situation will train the grip strength. In order to master the highest strength, we use various grips to challenge the palms, fingers and forearms.

The farmer's walking is the most common action. Pick up a huge weight with both hands and see how far you can go. Load as much as possible, keep your posture and walk for a distance or a period of time. Sometimes you walk a short distance with a heavy load, and sometimes you walk a long distance with a heavy load.

Pinch: Grip strength involves a lot of thumb strength, which adds different changes to the original training. Generally, two bars (smooth face outward) are used to grasp. Start with 5-pound or 10-pound strips and knead them into a ball. Don't let them slip away. Once you get used to it, you can start to gain weight.
