The rack deadlift is great for lifters with less range of motion, but can also be used to work the top range of the deadlift with a heavier load.
Typically, the rack deadlift is set up with the bar just below the knees, but just above the knee is fine too. If you don't have a rack, use a few 45 pound Olympic plates to elevate the bar into position.
One of my favorite books is A Book Of Five Rings by Miyomato Musashi. Musashi was a badass 17th century Japanese swordsman who never lost a duel in over sixty fights. This book outlines his philosophy of success. I re-read it recently and was amazed by how many of his principles apply to a variety of areas in life, including productive strength training.
In Part One of my "no curls" arm specialization training series, I talked about the absurdity of most arm specialization routines. I proposed that most trainees do more than enough biceps curls and triceps press downs and don't really need more of either of them.
