1) do you really feel this machine helps place
less stress onthe lower back?
All I can tell you is it places less stress on MY back.
I'm willing to accept that you FEEL it places less stress on your back,
but, unfortunately, biomechanics says otherwise.
Look at a well done barbell squat from the side. NOT linear.
Look at the human spine. NOT linear. Our spines were designed, by
evolution or God (pick one), to be a horizontal non-load bearing
support structure of a four legged creature. Then those freakin'
proto-apes just HAD to stand up. And their spines adapted as best they
could, primarily by curving in a number of places.
Look at the path of the bar of a Smith machine squat. Designed for a
non-humanoid creature.
Are you a non-humanoid, Bob? A Denibian slime worm? A Jovian fire
dragon? NO!
