The deadlift is the easiest lift to perform, and the most difficult to train, for me. It lends itself to over arousal, since there's really no "over" with deads, and I love that. But, past the novice stage, I've always burned out pulling heavy from the floor. The result was that I was forced to consider one of my least favorite things: conjugate periodization. My deadlift is really the only lift I figured out, and trained, alone.
