Dr. Nick Tiller is an exercise physiologist, researcher, author, and longtime endurance athlete with a strong interest in one question: how do we separate what actually works from what just sounds convincing?

Scott and Nick dig into supplements, recovery tools, wellness influencers, social media, and the challenge of making good decisions in a health and fitness world full of conflicting information. They also talk about ultrarunning, including why Nick believes the training can be beneficial while repeatedly racing for 12, 24, or 48 hours places a very different kind of stress on the body.

They get into recovery too: massage guns, compression boots, cold plunges, and similar tools may help you feel better, but true recovery still comes down to sleep, food, rest, and time.

The bigger theme is critical thinking. Learning how to make better decisions instead of chasing every new supplement, hack, or wellness claim that comes along.
