You wouldn’t believe how much mis-information there is on this! Just a simple search on google will give you thousands of differing opinions on whether it is a good or bad movement, some will claim it’s no good at all! I would say take a look at Dorian Yates and ask yourself, does this man look like he knows what he’s talking about when it comes to a big back? I really like this lift, it feels like it’s really hitting the lats hard performed properly, and unlike standard barbell rows or Pendlay rows, there is far less stress on the lower back. The biggest problem most have is executing the lift properly. Dorian used to use an underhand grip, but as the weights used were getting huge, he ended up doing the inevitable and injuring his bicep tendon and now uses a narrow overhand grip instead. The main two mistakes most people make are flaring out the elbows, and pausing at the top of the movement. This is a power movement and should be treated so. Use the heaviest weight you can and keep the body still! For a more in depth definition here’s the man himself.
