This is my first post but I've been visiting this site for a few years now. I have a question for anyone out there. I received a Powerball at Christmas for strengthening the wrist and forearms but on reading the instructions it said it was not to be used by anyone with any heart conditions. On the assumption that having my mitral valve replaced (mechanical) I now didn't really have a "condition". What do you think? Regards to all. Doug.
