There is absolutely nothing more functional in the weight room than deadlift. Soon Walter can hoist up the Mrs. and carry her around the house.
If you haven’t deadlifted a high weight you can’t understand. First off you’ll never get yolked up because you are keeping the reps under 5. Doing low reps at near maximal lifts does not cause hypertrophy. Now think of all how much of the entire body is used in the deadlift. It’s mano y mano you and the bar. Grip strength, hamstrings, Glutes, back, and especially the core because you must brace the core to pull 2-3X body weight. There is a great story about this track coach who took a little 9th grader and got her eventually deadlifting over 400 lbs. with almost no weight gain (more than 3X body weight) and she eventually was a US olympic gold medalist.
