There are many times that I find myself stooping down low to pick something up off the ground and lifting it to at least waist high. It might be a 50 pound bag of dog food or lifting a lawn mower into the back of a truck. In other word this motion of bend down low and give it a heave happens to just about everyone and that’s when doing straight leg dead-Lifts comes in handy. I also think of this exercise when people are having discomfort in the lower part of the spine. The effort put forth by doing this lift really pays of if you have a job where you stand slightly bent forward at an angle like a massage therapist or a auto mechanic.
