I see the other post discussed how this is related to being ready to fight for your city, but did non-Hellenic people also work out? Did their cities have gymnasiums? If they didn’t, did this make the Greeks a stronger army considering phalanxes might have been a shoving match? Kind related questions I’ve had.
