I have been doing foundation 1 exercises for a few months now and I am interested in starting the stretch and movement series. I have two spinal fusions: my L1-L4 and C4-C6 vertebrae are held together with titanium rods. I was unsure if the Foundation 1 exercises would be feasible or would hurt, but I've been consistent since about August and my body feels so much better! F1 has had a much more positive effect on my back than the exercises prescribed by my physical therapist.
I know this isn't the place to get medical advice but this community is familiar with the specific exercises and my doctor is not. I want to know if you think the stretch exercises might be a waste of a purchase (not operating with much of a budget here) because the physical condition of my spine is different than a natural spine where there are functional joints between all the vertebrae.
