Time for strategy to replace brawn. Most jars will open easily if you can release the vacuum. Imho the best thing to use is a bottle opener/can piercer, using the rounded end and very gently just barely lifting the edge of the lid. You don’t want to break/chip any glass or bend the lid so far its functionality is compromised.

i heard somewhere that its not actually only strength that makes it easier for men to open jars, but something to do with the skin. like something to do with the reason their skin is rougher gives them more grippy hands, so they actually just need less physical strength than a woman to open a jar. that would mean even if a man and a woman had the same grip strength and hand size/shape, there would be a jar that the man could open but the woman could not.
