The thing I dislike about cast iron cookware is that it is extremely heavy. I sprained my elbow last year and couldn’t use any of my cast iron pans for three months. My mom hates them too, and avoids using them whenever she visits.
Some of ours are pretty heavy too. We also have some stainless steel pots and pans we use a lot and they're quite a bit lighter. But I should also mention we stopped using aluminum cookware back then too.
God, this. I've got tennis elbow and I dread lifting heavy cookware.
