Not getting injured is the one I have always struggled with. As you have correctly pointed out it is probably the most important thing you can do to keep fit. After 17 years of stop start I had gone from potentially world class athlete to unable to even do a sit up without agonizing pain. On the road to recovery again now (2.5 years in), hopefully for the last time. This time I have invested heavily into medical help to solve the problem from the core and not just from the pain perspective. It seems to be paying off so far and I would recommend the course of action I have taken to anyone else suffering from back problems (severe scoliosis in my case due to office cave man exacerbating underlying imbalances from a serious accident). My regime is chiro, sports massage, a physical therapist who doesn't hold back when doing active release and core strengthening exercises once capable. Also know when is enough. It took years to start listening to my body and to realize I couldn't train like I used to.
