Speaking of back pain, I injured my lower back quite badly about a year ago.  I was doing bench press and wasn&#x27;t able to complete the last rep.  Instead of calling for help, I (stupidly) attempted to roll the weight down to my knees and then stood up and set it on the ground.  I immediately felt a sharp pain, and for the next week I wasn&#x27;t able to sit down (I had to constantly stand since bending was painful).<p>Ever since then, I haven&#x27;t quite recovered.  My back feels fine most of the time, but every few days it aches quite a bit.  I recently tried to start working out again and the pain flared up immediately.  I&#x27;ve spoken to a few serious weight lifters, and they&#x27;ve told me that reverse hyper machines can help rehabilitate mild lumbar disc herniations (which is what I have).  I can&#x27;t tell if this is &quot;bro-science&quot; though or something that actually works; a quick search on Google Scholar reveals nothing.  Also, most gyms do not have reverse hyper machines, so I would have to drive out of my way to use one, or purchase one.  Does anyone have any experience with these machines?
