Agree. Although, when I'm doing my working set of deadlifts (after a series of warm up ones) my whole body is by then heaving for air and on fire after the last rep. It certainly gets the heart rate going. Now I don't do those every day, of course, but squats I do. Either as high rep/lower intensity warm up for other exercises, or low rep 5x5 heavy as a primary target of the day. They never fail to kick-start the body.
