Depending on which program you are currently using, you may want to use the program from my newer book Strong Women, Strong Bones, which includes detailed strategies for preventing and treating osteoporosis, or consider the online Strong Bones program. Also, in your note you mention calcium but not vitamin D, the latter of which is essential for calcium absorption. It is difficult to get enough vitamin D from diet alone so you may want to consider a supplement such as Citracal, which contains both calcium and vitamin D.
I also want to note that the gain in bone density in the first year is great, and so is staying the same thereafter. Maintaining the same bone density from year to year means that you have not lost any bone, which is also very important.
