I'm not familiar with it. Sorry.
In his recent book, mass made simple, coach Dan John describes barbell complexes as being on of three integral parts to mass gain, reasoning that barbell complexes increase "time under the bar".
While obviously not appropriate for a novice trainee, I am curious as to your thoughts on this training method for putting on muscle mass in the trained athlete.
I'm not familiar with it. Sorry.
It would be nice if people would stop trying to pit one well respected coach against another. Read, experiment, and come to your own conclusions as to which methods work best for you.
Dan John says that, and Dave Tate says Barbell complexes are the best way to cut weight just ask Body Builders....CONFLICTING INFORMATION SUCKS
As does having to evaluate for oneself.
DJ did write an article about that once, he kept writing about people saying, "I wonder."
Just try it and see. One session of doing beats ten sessions of wondering.
