A nice way to slip the spine into place is to place both hands on the spine and push as you tilt and rotate your hips from side to side. Move your hands and continue to press on the spine center as you move your hips and let the wave coming from your hips relax and align the spine as well. You can also do this while wearing a vest or armour if you slip a strap under the plate or vest and pull on it with both hands.
