some people may find it hard to follow the instruction by having only pictures. If a step by step guide using video tutorials is provided, it may be able to reach out to the crowd. useful tip bro...upvoted. will be great to try one or two later in the day, especially the part on aligning the backbone. my chiropractor is an ass. couldn't solve my problem and keep fleecing me off more money. fortunately I came across this. great work bro.
