I want to mention that for stong bones as well as muscles you have to have a good diet eating foods that are loaded with calcium and minerals
look up a list of them and eat them , you have to do weight resistance also
I would recommend using a weight vest. it makesbone stronger if you wear it while just walking or doing any activity. The vest is very comfortable because it is actually made for a womans body my doctor said my bone is getting stronger from doing my weight vest walkng with nyknyc. I am so happy because I am afraid of drugs.
