Hoping I'm in the right subreddit

My nails are crazy weak,I can split one back into the quick and it takes literally years to grow out because it keeps resplitting. I have broken them on laundry baskets and grocery bags, they also peel like layers. I don't wear polish, I am quite active outdoors with physical labor. I'm at a loss on how to stop this or at least slow it down, any ideas for me? Thanks
