Question: weak knees and wrists??? i have pretty weak wrists and knees are there any excersises or anything to help strengthen them????any advice???

Answer: lift legs to build your quads and hamstrings to hold up your knees better.  you can do wrist curls to build forearms for your wrists.  Also the impact and stress from lifting and excercising can strengthen your bones and assuming you don't hurt yourself will probably help the parts you're worried about
