The back extension exercises that @Jerez mentioned are great. I usually do 1 set of 10 reps of the 45 degree back extensions then rotate my body 90 degrees both left & right to work the oblique. I also feel the side-ward extensions also stretches the back muscles in a diagonal fashion. Making them a bit more resilient. I usually repeat the same sets two more times with first a 10 lb weight then a 25 lb weight. Really good for lower back conditioning.
Besides strength, I believed resiliency and flexibility are very important qualities for the lower back. I find the cable exercise machines are great for working on upper and lower body separation issues. With the cable machine, I can also work on separating the head from the upper body. An additional degree of separation within the body. Great for reconnaissance purposes while skiing steeps, bumps & trees.
