the yoga postures for the back that i do, love 'em or hate 'em, all do something positive. these are them in order of sequence:
boat
bow
camel
bridge
wheel
the only drawbacks i know are that they are all in the same range of backbend. however, gravity and the way in which you're based on the ground (on hands, on shins, on belly, on shoulders, on feet, etc.) all make each work a little bit different. add this to good mornings and supermen (**** you, lousy haters ) and my back gets stronger every week.
