I would be very sceptical about using weight training, and squatting and deadlifting in particular, as remedies for back pain. These exercises can bad for you if you have pre-existing issues, EVEN if performed with proper form. Exercise is obviously useful, but I see no clear reason why putting your body under serious loads is a good idea. Most serious amateur powerlifters and bodybuilders, for example, end up suffering from back/knee/shoulder issues at some point. Posture and mobility deficiencies can be improved in other ways, but this normally requires more thought than hitting the free weights.
