When you have an end game wide representation, I'm wondering if the inferior glute max, when it starts to bend the apex of the sacrum under, is similar to butt squeezing or not. And you should be careful with the exercise selection or liking a narrow. Or is it a different type of inferior glute max activity? It's not a different type. It's just a different starting condition. So if I start with an anteriorly tilted sacrum—if this is the base of the sacrum—and I bend the apex under, that's the end position. If I start here and do that, it wouldn't look the same. But the muscle activity, because I'm trying to compress the same space, the strategy would be the same. However, because the starting conditions are different, the end appearance will look different. But if it's the same strategy, I have to take the same precaution against reinforcing it. So if I'm a wide and have posterior lower compression or I'm a narrow and have posterior lower compression, it's highly likely I'm going to try to do the same thing at the end.
