I would tend to agree with your statement. I do back strengthening exercises every day but only to stabilize my spine after a compression fracture almost two years ago. I doubt it's doing anything to help me grow new bone but it has helped minimize any pain from that fracture and to ensure that I am functionally able to move and lift items in my daily life and in the resistance training that do that does hopefully help me build bone.

I had osteoporosis in the lower lumbar spine. I took Tymlos and then switched to Forteo for 6 months. During that period I hired a personal trainer and gained enough strength to deadlift my body weight. Deadlifts greatly strengthen the muscles supporting your spine. My numbers improved significantly and was able to come off the drugs. Lifting heavy weights may not be for everyone, but it works. Good luck!
