I believe Rows suck as a DL accessory and here is why.
This has been bothering me a lot for a lot of time, lifters all around the globe treat Barbell Rows as ideal deadlift accessories. My opinion is that they are not since you are using a very light weight relative to deadlifts, while concentrically using your back musculature to row the barbell. In this motion the hip extensors (hamstrings and glutes) as well as the quads are contracted isometrically whereas in the deadlift not only do they contract concenctrically, but at maximal loads as well. The only "benefit" that the rows hold over the deadlifts are the concentric movements of some muscles, such as the lats, the traps etc.
My question is, why would we pick a row that uses the big muscles really submaximally instead of lifts such as the RDL, Good mornings etc. to train a lift like the deadlift where these muscles are loaded at their maximum capacity?
