Being evidence based is actually quite hard. The evidence is not always clear, and I would say more people look at data and make poor interpretations than actually take that data, put it into context and understand what value there really is to it.
The glutes are a great example for this, because if you didn’t know any better you’d think the abundance of data we have covers how you should train for glutes, when in reality there is almost no research done directly on the largest portion of the glute max.
