Everything about that video is awesome.
What's wrong with is form? Really?
You might say there's too much swing. That keeping his shoulder in a fixed position would give him better muscle overload. You know what's actually gonna give you better overload: getting that 25th rep in. And hell, you could even argue that he's getting a bit of a pre-stretch out of it.
You might say that he's rotating his torso too much. I'm gonna have to give that a no. Look at how much the angle of his shoulders moves (very little) in comparison to the distance the dumbbell moves (a lot).
This video is just an example of what kind of form on dumbbell rows will give you the best results. I've seen people do perfect dumbbell rows with 45 pound dumbbells all the time. I've seen others do their dumbbell rows by making their elbows touch the sky and rotating their body because they think they're doing an oblique move. Whenever I've seen jacked people do dumbbell rows it looks like this.
Manson doesn't have that many good songs. Beautiful People is a good choice.
