Exercise that builds bones!

Hi,

I just turned 67, and I am trying to strengthen my bones through running and weight lifting. I have consistently walked a couple of miles every day for many years, but it hasn't been enough to ward of osteoporosis. Ive set a goal of running daily ( training for a 5k in May) and lifting weights at the gym at lesst 2x per week. I would love to share ideas and encouragement with others!
