Greetings, To avoid ruptured spinal disk, NEVER lift anything heavy without bending the knees. I was told by my chiropractor to get your body as close to the heavy object as you can and then bend the knees as you lift. Anything that causes you to have to hump your back and stretch it can cause tearing, stretching of muscle tissue and possible rupture of spinal disks.
