I find that well-executed strength training (i.e. with proper form) eliminates all kinds of back-related issues for me. This talk has been really eye opening for me:
For me weightlifting is about staying in shape for things like mountain adventures, feeling great, looking good. But Arnold-look is a silly goal for long term wellness, and so are the methods to get there. Once I stopped pushing the numbers and focused on more repetitions, I never had any injury. That's worth much more than some momentary number of kilos/pounds you did today - nobody will care about that tomorrow, but injuries remain, sometimes forever.
