Dead-lift
The Dead-lift is well-known around the bodybuilding world as a super exercise. It works most of
the muscles of the upper body along with the hips and thighs. A person could build a very strong
body by doing only Dead-lifts, Dips and Squats. You must use much care when doing the Dead-lift,
as it is a very dangerous exercise. Back Extensions have no downward stress on the spine. They seem to work fine for strengthening the lower back, but they will not build other muscle groups as the Dead-lift can. You must decide for yourself. If you try doing Dead-lifts, start with very light weights until you get your form down. If you feel the pain all the way into the nerves of your back, you may want to drop the lift, too.
