There are only two beginner programs that I know of that use the 1x5 for main deadlift work- Starting Strength and Stronglift 5x5
Starting Strength, as written in the 3rd edition, has you start with the traditional stereotypical squat/bench/deadlift/OHP, but specifically states that after a couple of weeks you should move onto the following-
And also add in chins as assistance later down the road.
Stronglift, because it's pretty much written for the lowest common denominator, ignores the power clean entirely and instead does-
A- Squat/Bench/BB row (Though I don't remember if the row was actually there back in its original incarnation)
Point being- Most people who tell novices to do just the squat/bench/deadlift/OHP are regurgitating shit they heard from people who either bastardized SS/what Rippetoe said and/or bastardized 5/3/1 and what Wendler said.
Rippetoe is a big advocate of the power clean and Wendler is a big advocate of chin-ups/getting proficient with vertical pulling.
I don't think there's any credible authors/trainers out there who says you should do nothing but squat/bench/ohp/deadlift. Hell, Rippetoe is who people typically point for for advocating that stuff, but they forget that he likes the power clean.
