Okay, so you're actually aware of RSI. So what, exactly is it you don't understand about the idea of them happening from a much heavier weight, like a KB?carpal tunnel syndrome, is the carpal ligiments wearing in to their eer tunnel, the carpal ligaments work the fingers not the wrist, which is why typists suffer from it.it just happens to be in the wrist were it happens, it isn't caused by movement of the wrist
RSIs in general are years in the making, so hours a day, week after week for years, nobody got tennis elbow on 12mins hitting a ball 3 times a week
It's pretty clear you're just looking to pick a fight. You didn't even take up the issue with the guy who posted the warning. You're ridiculous sometimes, mate.
