...it wont be a problem getting into shape for it, but I broke both of my wrists when younger and one of them had to have pins in. It still gives me a bit of jip whenever I get an impact on it when playing sports. So I haven't done weights or pull-ups for years as they hurt and feel like they're under pressure.
Can I have some suggestions of the best way to gradually build up the muscles in my wrists, so that I can do the monkey bars and rings, please?
Any advice appreciated. I've got 8 months before it happens, so there's plenty of time...
