cycling and back posture

Its amazing how much damage incorrect posture positioning can cause.

Not just when your riding on a bike either, you need to be careful when sitting in all manner of chairs, especially considering the amount of time people spent slumped over their desks each day.

Our user asked: "I am a cyclist and was wondering what the proper posture should be, from the perspective of spine health. We are constantly warned against flexing the spine for fear of herniating discs, but most cyclists ride with the whole spine in an arch. I have been trying to find out whether this is actually advisable, or whether we should be seeking to maintain normal lumbar lordosis while riding. I can think of arguments for both, but wondered what an expert would think."
