Rounding of the back during Deadlifts
*475lbs on the bar*
In a perfect world your back would stay perfectly flat during the entire range of motion. Yet we do not live in a perfect world.
But there is a huge difference between upper back rounding and lower back rounding. Upper back = acceptable. Lower Back = Very Bad.
The fact is that the greatest Deadlifters in the world, the ones that lift the absolute most weight lift with a rounded upper back. Is it pretty? No. Is it safe? It's safer than you think. I'm by no means an expert on anatomy, so I rely on the opinions and studies of experts. The overwhelming conclusion is upper back rounding is okay but should be reserved when possible.
For me 475lbs is pretty damn heavy. Close to my current max. I can certainly be much better at this movement, and I plan to be better!
