I have been going to the local Osteostrong for 14 months. I pay $159/month for a once a week visit that lasts around 15 minutes. Each visit begins and ends on a vibration machine followed by a supervised routine on the 4 Osteostrong machines. I have been consistently exceeding the threshold level on the machines for bone growth with no aches or pains, but I am fit and have been weight training on my own for years. Recent DEXA showed lumbar spine went from -3.4 to -3.7 while my right hip neck improved from -2.1 to -1.4 (first time I've had a Z score above 0 in years), and my right total hip went from -1.9 to -1.5. Left hip stayed the same. I have never taken any bone drugs but do take Bone Up and extra vitamin D3. Since my DEXA results were a mixed bag, I am not sure if I will continue Osteostrong or try to find another weight training program that is more focused on the spine.
