Degenerated disks and deadlifts - why no back extensions or exercise bike
I'll start off with that title, which is what I used in the search earlier. Last week my deadlifts finally got above my bodyweight. I know I know, I'm weak; I've lost quite a bit of strength these last 10 years, and began Starting Strength deliberately lower to get in much more practice and time getting the lifts right before I got to heavier weights. But all weekend my lower back has been aggravated, mostly in the mornings, and less so as the day goes on. I'm suspecting my deadlifts and possible bad form as I'm running out of steam by the time I get to my deadlift block - only have an hour to train in the mornings before work, so I generally skip the rest periods between major exercises, other than what's needed putting weights back and resetting the rack for the next exercise. I also suspect I might want to concentrate for a short period on strengthening the associated core muscles and spinal erectors, along with my grip strength before loading up heavier deadlift loads. That way I can ensure my core is keeping my back straight. I'll probably back off a bit and work some lighter deadlifts, along with including some RDL's into my program; sorry Rip, I know I'll be NTDP, but as I get older I find I have to improvise things more often than not anymore.
So why did I search for degenerated disks? Because over 20 years ago, shortly before retiring from the Air Force, I had my first major injury that started a period of fighting herniated disks. Upon MRI, it was discovered what is no surprise, L3, L4 and L5 were diagnosed as mild to moderately degenerated, with some occasional bone to bone contact. No surprise for anyone that spent a career in the military working and living in the field. Fast forward to this time 10 years ago, I slipped and took a partial fall down a flight of stairs that caused me 2 months of serious pain due to those disks. I had trouble walking, standing, setting, lying down, sleeping; everything was painful for a month and not even 1000mg Ibuprofin at a time helped. About a month in, borrowed and began using my parents' exercise bike which really helped begin the healing process. By the end of the third week, I was out of regular pain and mostly back to normal.
Anyway, sorry for the longwinded narrative. Because of the pain this weekend, which is very mild, it did get me thinking about what Rip's and the community's views toward lifting with disk problems especially in us "older folks". So I searched for that here, and one thread I came across Rip mentions not doing any back extensions or exercise bike riding as they only aggravate the condition. But even after reading through the entire 11 pages of that thread, I didn't find a reason why mentioned. I would like to ask why that is, since I find reverse hyperextensions help me a lot when my lower back is sore (mostly in the mornings), and have found the exercise bike to really help with my recovery when I had that bad injury. If anyone could enlighten me why the thinking is these two exercises are bad, I'd like to hear. Thanks for listening
