We grunted our way through the day before this great episode! The main training topic was a new study on the dose-response curve for intensity, finding that only 11 minutes led to 80% of the benefits…

Before we get to the study, we wanted to talk a little bit about the grunts that Megan mentioned because we got a lot of messages.
I think on Friday, I promoted the new YouTube video where Cody does this grunting montage, and I shared the grunting montage on Instagram, and like an hour later, I deleted it, which I rarely do when I think something's funny, but I got so many comments from people being like, "These grunts are too much." And I'm like, "This is just my authentic truth.
Can you imagine opening that up on, like, an airplane and not knowing that your volume is on, and all of a sudden you're, like, having to explain to the person next to you, you're like, "This is actually a guy at an elliptical.
Well, maybe that's where the power comes from, which leads to the first question from a listener, uh, or first comment.
Funny story about the power of grunts, which, by the way, is not just a David thing, which makes me feel good.
I was so worried this was just me grunting on the treadmill and the elliptical, and it wasn't something others did.
