According to Stu McGill, low back pain researcher, we need to be training our core for stability and endurance in order to prevent low back pain. This exercise fits the bill. I picked this one up at TEST sports performance at an internship back in undergrad. Plank variations like this one promotes stability at the shoulder (serratus anterior), abdominals and cervical spine.
Give it a shot and report back. Let me know what you think,
