I obviously have a very strong personal interest in this topic. This is a philosophy I generally agree with too.

People are becoming less active and more overweight, which means they are becoming less fit and less able to tolerate the activity and loading for which we were designed. Recent expert advice highlights that the best way to prevent back pain is with
exercise.
Rather than advise people to avoid lifting, they should be taught to make regular lifting part of their everyday routine. To build the muscles of the spine, the load must be heavy enough, as with any weight training.
The part about being overweight probably doesn't apply to most cyclists, but we as a group don't do enough resistance training, and many cyclists (including me lately) complain about back pain on the bike.
