By the time a lifter has developed a 2x bodyweight deadlift, he’s probably not considered a beginner. Certainly, a 3x bodyweight deadlifter has spent enough time in the gym to squat properly. While the deadlift is a great exercise, especially for beginners, I believe it is too taxing to be THE core lift for advanced lifters, whether they are competitive weightlifters or sprinters. Even many powerlifters, who train to deadlift competitively, don’t deadlift nearly as often as they squat because it is too hard on the body, and many Olympic lifters don’t deadlift at all. Most do squat. Keep the deadlift in the program, but there is no reason to drop the squat.
