Summary
We got way too invested in dog food models before this amazing episode! The main topic was a new study on passive heat training (like the hot tub or sauna) that acts as a missing link between theory and real-world proof.
The study found that 5 weeks of hot tub training increases hemoglobin mass and VO2 max, which coincides with improved running economy. WOW! We break it all down.
And this one was full of incredible topics! Topics: a date night game that should have stayed in date night, Hans Troyer and Jade Belzberg’s wins at the JFK 50 Mile, hard hill strides to break through neuromuscular lulls, questions on heat training, unexpected events and prosocial behavior (including a study involving Batman), a 47-year study on athletic aging, persistence hunting science (and how that relates to human responses to heat), influencers, traveling with gels, stacking training plans, pre-wedding advice, and lots more!
If there’s one takeaway from the science in this episode, it’s this: BATMAN. It will make sense soon.
We love you all! Huzzah!

| 0:00.0 | Well, welcome to the Some Work All Play podcast. We are so happy to do with you today. |
| 0:04.6 | Happy Tuesday. It's Tuesday. And I'm feeling ready for a grocery store date on this Tuesday. |
| 0:09.2 | Oh my gosh. What a night. So we got a date night on Saturday. And it was incredible. We only had about an hour. And so we went to the place in Netherlands to get chicken tenders, which was a great way to start. Chicken tenders in football is amazing. We sat at the bar. We had chicken tenders and French fries. It was great. It was such a vibe. If you told 16-year-old me that I'd have a wife that views that as a really good night, I would be the happiest kid on the planet. I was like college football. I'm here for it. It was fun. But somehow it only |
| 0:38.0 | took 30 minutes. I think we both eat fast. It's like a combined trait of both of us. Especially with chicken tender. It's made to just like, don't know, no, num, num num num. Chicken tunders and honey mustard. And we were out of there in 30 minutes, quite filled. And like, it was fun. Alpine Brickhouse in Netherland for anyone that wants to try it, it's incredible. |
| 0:55.4 | And then we're like, what do we do? |
| 0:56.7 | Because usually we'd go on a little walk. quite filled and like it was fun. Alpine Brickhouse in Netherlands for anyone that wants to try it. |
| 0:54.6 | It's incredible. |
| 0:55.6 | And then we're like, what do we do? Because usually we'd go on a little walk. It was cold outside. And we're like, no, probably not walking today. And it's a mountain town. So not a lot was hop in within town. And we had the great idea. We're like, we're just going to go to the grocery store. and we're going to wander the aisles |
| 1:10.6 | and kind of view this like an art museum trip. |
| 1:12.6 | It was the best. |
| 1:13.7 | It was like going to go to the grocery store and we're going to wander the aisles and kind of view this like an art museum trip. It was the best. It was like going to the museum of modern art, but the art is Freetos. Do you actually remember early on in our like dating history? I think it was our third date. We went to an art museum at Duke and just walked around and they served us like milkshakes that had some kind of alcohol in it and we just walked around and made jokes for an hour. That's one of the moments when I knew I wanted to spend the rest of my life with you. Same was making fun of art. It's so crazy because to me, you know, a lot of your life at that point, you were just so smart you're doing all these things in field hockey. But then I figured out, oh, she's the funniest person I've ever met. We were both making fun of art and uplifting art at the same time. And I actually think it was one of the last cultural, true cultural things we've done. When was the last time we've been to an art museum? Oh, Megan, Megan. We have kids now. I'm not going to, that's not going to happen anytime soon. But it wasn't that long after that date when we went to the art museum, when I bought you a ring, I went to Macy's and got the cheapest ring they have being like, I don't know when this is going to come in handy, but eventually it will. And I might have jumped the gun just a little bit. I think on the eighth date, I was like, whoa, whoa, whoa, hold your horses, buddy. But it worked out. And it got us 15 years later to the grocery store in Netherlands, viewing it like an art museum. And okay, it was actually like some of the most fun I've ever had. It was incredible. Should we say the game we played? Oh, for sure. We played Mary Fuck Hill with a variety |
| 2:35.3 | of different things. So it started in like the celestial seasonings tea aisle. It migrated to Jello. |
| 2:40.0 | And then it got real freaky by the time we got to dogs because we were looking at the dog food. |
| 2:45.2 | Oh no. Choosing dogs on the packages. Yeah. Yeah. And we probably shouldn't have said that, actually. |
| 2:51.7 | I mean, it was funny. But that's the big advice. On your next date, go to the grocery store, |
| 2:56.5 | play Mary Fuck Hill. With a variety of food items. With a variety of things. Not humans, not humans. |
| 3:01.0 | But dogs probably safe. Okay. Okay. What happens in the grocery store stays in the grocery store. |
| 3:06.4 | But I think I have to say, |
| 3:07.9 | can I say your fuck dog choice? Oh, why would you say this to so many people? Because it's hilarious. |
| 3:14.9 | There are all these dogs and all these like dog feed packages. And of course, this is like |
| 3:18.3 | hypothetically. You have to choose. And you chose the bejean. I mean, you couldn't tell the size of the dog. |
| 3:24.6 | You just saw the face. Okay, the face did have like a lot of curiosity and wonder. Yeah. You literally chose a bejean. That dog could get it. Okay, what's going to say? Episode time. I chose a husky. I feel like this says something about us. I chose a husky and you chose a bejean. Who the fucker's a be jean? |
