Is there spinal exercises, that when done, can help you build muscle faster?

[Steve Smith]

I heard from a friend of a friend that there is special exercises for the spine, that when done, can help you build muscle (all over your body) faster. I'm not sure if they're supposed to help activate hormones, or do something entirely differently, as my friend doesn't really know the details of these exercises. I've tried researching about this on google, but have found nothing that helps.
