What you have to understand is that all of your nerves at some point run through the spine. So let's say that you get Spondylo (where the disc slippage begins)- the result will be a bulging intravertebral disc, the question is this: will the disc detioriate, push out the front, or push out the back? Either way the nerves will get trapped in what is called "forimanal narrowing" and probably some form of "facet arthropathy"- since you can't (in the U.S) replace the discs, the only thing you can really do is try to straighten the discs that are "subluxated" by some type of manipulation, which is usually done by a chiropractor. One would only hope that you would be referred to a chiro who takes X-rays and understands what your MRI or neurologist states in his limitations. This may ease the pain somewhat (along with P.K's)- but then you have to deal with the constant adjustment of the surrounding musculature. They may spasm, they may constrict, they may stretch, and it will all be dependent on your genetic structure, how you sleep, and what you do during the day.
If your disc is bulging out the front (rare) the last thing you want to do are hyperextensions. If your disc is popping out the back, the last thing you want to do are flexion exercises. Sitting may even be a problem because when you sit, the muscles relax and the total weigh of your UB rests on these fucked up discs which in turn, press even harder on the nerves. The nerves will inflame and the opening (tunnel) for the nerves will seemingly constrict.
Back injurious are insidious: By the time you realize that your back is severely fucked up, the damage has already been done without your knowledge. Like the previous poster (
sorry) said, you will wind up on the floor crawling around the damn house wondering WTF?
Deadlifting is a great way to build total body musculature. It is one of the "kings' of all exercise, but when you get older, not only will you NEVER attempt them again, you will also wish you had NEVER done them in the first place. There is a point in the deadlift during the lift where your weakest link has to be incorporated. I firmly believe that this is where it all starts.
Even Frank Zane says if he had to do it all over again, he would not have lifted as heavy and as long as he did. Sure, he developed fantastic side delts, but he says he's been paying the price with daily pain ever since- to the point of where he can't even work his shoulders anymore.
when you are young....ahhhhhhhhh... to be young and have a chance to do it all over again, knowing what you know now.
Good luck my friend. The Pain Killers and the anti-inflammatories will fuck you up worse than your back in the end. At the same time, I've never met anyone who has had a "successful" back surgery to where there is no residual pain.
this is why Workers Comp Insurance companies fight tooth and nail over back injuries. They are insidious, they are hard to "prove" with even MRI's, EKG's, Cats, and X-rays, yet they are very real, and just about 80% of the population sports a sore back at one time or another- or eventually.
Call it wear and tear, old age, whatever. I say, be fucking careful NOW and think real hard about those special "lifts" you perform in the gym. Just cuz someone say's they work, doesn't mean they are not permanently detrimental to your health.
I could start another diatribe on the idiocracy of bench pressing. I'll just count my blessings that this isn't a powerlifting forum. 
one of the very few smart comment on here. i guess jhonny moron will ignore it. But yeah whats the point of destroying ur body because your insecure about your muscle mass... so many heavy lifters destroying their back for nothing...
i also agree that becnh press destroys your shoulders. In fact the helathiest way to workout is to do dips for both chest and tris. crunches for abs. and biceps curls. and voila you ve got a healthy and impressive enough physique for 99%of the population. now everything else is predeterminated by your genetics, your somatotype. If you ll look ''big'', ''lean'' etc.fact is lifting weights works the same for everyone whatever gender and age, it builds muscles period.
i too looked great when i lifted religiously for 5 years in a row being ''on'' creatine . this is also when johny daddy waddy looked his best. round full muscles, tons of water retention...then i hapened to get a life and meanginful relationships . I didnt care much about having the biggestmuscles and focused on more important things in life. Do not destroy your body for nothing you ll regret it later. train healthy and do other things, seriously.
