Hi Rubyz~
I just came across your posting....regarding Osteostrong.
The one near me was only 99 a month...had two machines and the vibration plate. I'm at the same bad numbers you're at..both in lower spine and hips. I weigh a bit more then you at 123 and am 5'4". Our weight or lack there of has a lot to do with how much we can achieve with re-building our bone density..as doing weight bearing exercises is tough to even start to get our muscles to the point of making even a small dent in our bones. I was lucky I didn't further injure myself trying to do the resistance machines...which I got up to 545 lbs. That was a great number..but one that I could never maintain on my own..and could also have caused major problems...I was lucky not to have further hurt myself with this type of exercise. I did rather enjoy the vibration plate and have since then bought one from Lifepro and use it daily..but am cautious also with that..so as not to cause problems I don't already have.

I am taking collagen peptides as well as bone building supplements...eating more responsibly, mostly plant based. I'm 77 yrs. young..and doing my best to stay upright and avoid falls and fractures. I will not take the medications out there for my osteoporosis...just don't want that added stress with the 'unknown' factors these can cause.
We have to be careful with what we do attempt to do for our bones..not wanting to cause further damage..so I would respectfully advise you to also think more about what exercises you do do...while resistance training is a good thing...we generally cannot lift enough weight to really make a difference...but the vibration therapy seems to work differently on our bodies by activating our muscles to do their job without causing injury when used properly. I would suggest that you look into this type of therapy..Nasa has a lot of studies done which are most compelling. Above all..be kind to your body..and follow your instincts...take care, I wish you well.
