You need no training or yoga.
Chiropractor training with the Alexander technique is expensive and yoga requires a great deal of passive stretching, which has been known to cause a great deal of injuries. There are no spiritual benefits to yoga that can't be found in any proper gym.
All you need to cure back problems is the humble full back bridge. Back pain is not voodoo. When the muscles in your back weaken from lack of conditioning (desk jobs, etc), the cartilage discs between the vertebra can easily rupture and shift. This causes nerve pain.
The full back bridge is superior to deadlifts and squats for (purely) strengthening the back because it teaches strength over a range of motion, so it conditions every spinal muscle, as opposed to deadlifts and squats, which give strength over no range of motion (ideally, the back remains static with deadlifts and squats). If you can successfully do a full back bridge (which can take a few months of conditioning), the deep muscles in your back will strengthen and your spine will properly realign itself as it's support structure develops. Your posture will improve dramatically. You might even gain an inch in height if you're prone to slouching.
