Osteoporosis and exercise

I was recently diagnosed with severe osteoporsis. I really need a list of some exercises that would help me. I walk, as the doctor instructed, and I am taking actonel 35mg.weekly and 1500mg of calcium daily. If anyone has any info about exercises that I need to be doing, please let me hear from you. I am really worried, as my doctor said that it is extremely severe in my spine and my hips.
