Hi, Thanks for your post. I have been doing OsteoStrong for 3 months now. As you stated, it's not a gym and I do aerobic and light weight-lifting on the side. My understanding is that the only way to measure bone strength/density is the Dexa scan, so I won't know until I have a new scan whether my bone density is increasing. However, I do feel stronger and the weekly session has prompted me to now increase focus on my nutrition. I wondered if you are doing any specific exercise to build muscle? I believe stronger muscles help with bone strength and density.
