Happy 4th of July 2009.
When in the course of human events...
We hold these truths to be self-evident...
Unalienable rights...
Life, liberty, and the pursuit of happiness.
Rounding the back during squat or lifts puts unequal pressure on the disc (as you can see in the right pic)...almost pinching/pushing/bulging it out the back...ouch!
Maintaining a tall spine, natural lumbar curve (left pic)...will go a long way in reducing the chance of back pain.
