Every few months, a new training idea goes viral, and suddenly it's everywhere. Zone 2. Cycle syncing. Ketones. Heat suits. Ninety grams of carbs an hour. The science behind most of these things is real. That's not the problem. The problem is that real science is getting stripped of context, flattened into a hot take, and sold to athletes who haven't built the foundation that makes any of it matter.

In this episode, Zoë and TJ break down five ideas that are genuinely overhyped, not because they don't work, but because the way they're being applied and marketed almost always skips the part where they actually become useful. They cover the five-zone model and why zone obsession can accidentally produce the worst possible training distribution, the booming female-specific training industry and what the 2025 research actually says about cycle syncing, performance supplements like creatine, sodium bicarb, and ketones and where the hierarchy breaks down, the ninety-gram carb protocol and why it's solving a problem most recreational athletes don't have, and heat training protocols and how fitness alone outperforms heat exposure for the vast majority of athletes.

The through line across all five: marginal gains are real, but they sit on top of a foundation. And if the foundation isn't there, no intervention is going to save you. Sleep, consistent training, fueling the work, and getting your brain right, those are the levers worth pulling first.
