"Backward walking burns 40% more calories and rewires your brain"—a claim that's everywhere from TikTok to the BBC. But where does this number actually come from? The original 2004 study found only a 17-20% increase in oxygen consumption, not 40% calorie burn. Meanwhile, the "brain boost" claim rests on a 38-person study measuring a 36-millisecond improvement on a single cognitive task—an effect that also happens when you just imagine walking backward while sitting still. This episode traces how genuinely interesting findings get transformed into sensational myths, and reveals what the research actually shows: backward walking has real applications in physical therapy, but the anti-aging hype doesn't match the evidence. We'll show you how to spot these misleading claims and what the actual science says about exercise that matters.
