<p>We basked in some amazing news before this great episode! The main topic was a breakdown of one of the most important elements of performance and health: blood volume. </p><p>Studies show that blood volume can seem to act as a synonym for fitness, with one finding that 6 weeks of training gains can be reversed with a phlebotomy that returns blood volume to baseline levels. Positive adaptations can happen in a few days, and it clearly matters for performance. If any other intervention worked like that, you’d assume everyone would be talking about it all the time. But blood volume is not discussed often! We pull back the curtain on the science.</p><p>We also talked about a new review article on exogenous lactate supplementation. It might be a brave new world in the next 5 years, but right now there are more questions than answers. We speculate!</p><p>And this one was full of cool topics! Other topics: the shockingly good news Megan has received in recent heart tests, our disdain for the Enhanced Games, recent age group doping news, the Satisfy Circle Pit, the true GOAT of endurance, running v. biking, uphill treadmill workouts, and lots more.</p><p>Yes, David actually hit himself for a joke on this episode. Podcasts are definitely the medium for physical and visual comedy.</p><p>We love you all!
