Since taking a new job in Wisconsin on March 8th, I have slowly gotten back into exercising/running over the past month.
I am now running 2-3 miles per workday (at a good 4.2 mph pace on average), and am about to begin strength training next week. I still haven't lost much weight (still around 270... my max weight was 295, and I weighed 195 in college - 14 years ago), but I'm feeling much more energized and healthy than I've felt since I was diagnosed with DDD and proceded to have 4 surgeries over the next 5 years.
Just wanted to share the good news. It is possible to get back to "normal" even after four fusions. ;-)
