First of all..........I don't have anything to do with, or would ever have anything to do with Chiropractic.
My back problems started long before I started c/c, in my teens, in fact, when I was diognosed with arthritis in my right hip.
What was missed in over thirty years of physiotherapy and osteopathy was the cause of the arthritis and this only became apparent when I got to around 54 and started training in spinal re alignment and relaxation therapies.
Mike comes close, with his comments, but the reality is more to do with alignment and it doesn't take a rocket scientist to realise that lifting, or manouvering heavy articles is quite definitely the most likely way to damage your back .
In my first job, I worked with 3 men in their middle 60's, all of whom amazed me, by their ability to shovel, dig and rake throughout the day, all with one foot well forward of the other and twisting their bodies to lift and shovel heavy sand or gravel upwards and onto trailers.
They obviously had no skeletal misalignment problems, whereas I at just 16 was suffering unexplainable pain in my back.
Since the cause was pointed out to me and corrective treatment administered, my quality of life has improved immensely, but at 61, the sciatic and spinal compression damage was present for too long and will only continue to degenerate, but..........although I was abandoned by osteopathy and physiotherapy 7 years ago, I have more flexibility now, than 7 years ago and can still do a 5 hour clean, but I will suffer and really should'nt
The best exercise you can possibly do, is walking or swimming.
As usual, I merely quote my lifes experiences in the hope that some may benefit, realising I will often sound opinionated, but I just quote the reality, as I've experienced it.
