Hiking is a wonderful exercise, especially with a weighted pack on. I don't know if I will be able to get back to hiking or not, because at the moment, I have a lot of foot problems. If I do return to hiking, I would like to get a hiking dog. That would lend a lot to a feeling of safety. But it is by far the easiest, most comfortable exercise I now of that gets good results. And a good dog would make it perfect!
