Ive had disc replacement at three levels due to disc degeneration similar to Ronnie, Jay etc, at your age I doubt you have got to that level, I would at your stage avoid exercise's as other have mentioned, you obviously have a genetic disposition to this type of injury and an educated work out plan is what's needed, do single arm movements for delt and back workouts singularly, this is something I have done since being post op, it avoids putting compression on the spine from both sides, all hammer movements where possible and machine shoulder presses and side laterals one arm at a time, get massaged regularly and use anti inflams sparingly and only where really required and rest that next day, but better exercise selection is paramount to stoppiong your condition progressing
