Bernie, that you so much for the carrying angle article in the latest newsletter! (I know it's a excerpt from your upper body book; I still need to get that one.)
I have never heard this term, but it makes a lot of sense to me. I believe I have a wider-than-average carrying angle. In the past I've sometimes thought I was being "lazy" by not being able to get my arms more straight when they are overhead (you can see an example in one of my YouTube videos - https://youtu.be/CLz8J1tB1sU?t=134) or I have blamed it on shoulder tightness. Although I do think the latter is a factor, I now believe it might be more to do with the angle of my forearms. It also explains why I prefer downward dog with my hands a bit wider than shoulder width.
As always Bernie, thank you for sharing your wisdom!
