I have weak wrists because I use them all day long at work (hairdresser). For me it's just over-using them, and I'm lactose intolerant so I don't drink as much milk and dairy as I should = calcium for strong bones.
over use, genetics we use our wrists a lot so its pretty easy to get tendonitis and arthitis
