That's bullshit.
We are talking about an individual, if you want to get bigger you have to get stronger in some way wether it is more reps, sets, time under tension, ect. In some way you need to get stronger to get bigger. There is no way around it.
Show me someone who has got bigger by progressively getting weaker.
This does not mean the strongest guy in the gym is the biggest, that is a different topic but when talking about an individual they will have to get stronger in some way if they want to get bigger.
That's great bazza.
