Is 30 kg grip strength good?
For a man, 30 kg grip strength is the average (median) at about age 83. It is above average for men older than that and below average for younger men.
For a woman, 30 kg grip strength is at or above the typical (median) value up to about age 25. Through the strongest years it sits below the median, is average again at about age 45, and above average from there on.
These figures read off the pooled British norms (Dodds 2014, twelve studies, 49,964 participants). The German norms (Steiber 2016, SOEP, Smedley dynamometer) run higher at every adult age: by 4 to 15 kg for men under 25, where the British curve is still climbing steeply, and by about 1 to 8 kg everywhere else. The same value therefore lands at a different age there. Source
