I have heard that weight lifting is the best way to combat bone density loss. I would think walking a lot would offset some of the potential for loss. For me personally, I usually go to the gym more in the winter months and ride more in the summer months. My gym only costs me $10 a month. I figure if I go 2-3 a month during the summer months I am getting my moneys worth. I do know that I can not lift like I did when I was consistantly lifting. I have to be careful to not overdo it. So to me biking does keep me in shape but it is a different kind of shape. My legs are stronger and core is pretty strong but my arms have gotten smaller since I am riding more than lifting.
