Muscle of the Week x 2

Since I have fallen behind a little with this segment and it was actually requested, time for catch up...

Real quick, I went to a wedding in Eunice, Louisiana this weekend and had a great cajun experience. A lot of travel:

flew to atlanta and spent thursday night there, drove to new orleans and spent friday night there, drove to eunice and went to the wedding and spent saturday night there, sunday at 6 am we took off driving reversing the trip, one hour time change and flew out of atlanta 6:40 pm, got to my actual house about 10:30 pm... luckily I start work today at 11...

These two muscles have recently been implicated in Unilateral Back Pain. The idea of the "core" is one that is probably not fully understood to the lay population or even many professionals. The core is the series of muscles around the trunk that helps to stabilize the rest of your body. In my short clinical experience it seems that proper core muscle training can relieve many symptoms of low back pain as well as improve performance of almost any activity. I would love to write a lot more... but I have to run to work... have a great day!
