The Hook
If you’ve spent any time on a treadmill this winter, you know the specific brand of existential dread that sets in around mile three. You’re either staring at a gym wall, re-watching The Office for the tenth time, or following a camera crew through a scenic but oddly static hiking trail in the Swiss Alps. But what if you could run through a world that doesn’t exist? iFIT is betting that the cure for indoor training boredom isn’t better reality—it’s better fantasy.
What’s New
This week, connected fitness platform iFIT launched a new series called “Realms You Can’t Reach.” Created in partnership with the design agency Huge, these aren’t your typical scenic runs filmed with a GoPro. They are fully AI-generated environments—specifically, five distinct worlds including a prehistoric “Dinosaur Island,” a futuristic “Sky Garden,” and a voyage through the “Solar System.”
The big tech headline here is the engine under the hood: the series is reportedly powered by Google’s Veo 3 technology, marking one of the first major consumer fitness applications of high-fidelity generative video. Instead of just creating a static image or a short GIF, the AI has generated seamless, long-form content designed to keep you engaged for a full 20-30 minute workout.
How It Works
It’s important to distinguish what this is versus what it isn’t. Unlike video game graphics (think Zwift or Fortnite) which render 3D models and polygons in real-time, this is video generation. iFIT and Huge used Google’s generative AI to produce continuous point-of-view videos. The AI “hallucinated” every frame of the journey, ensuring consistent lighting, physics, and texture that traditional game engines often struggle to make photorealistic without high-end PC hardware.
When you fire up your NordicTrack or ProForm machine, the incline and resistance will sync to the virtual terrain just like a standard iFIT workout. As you ascend a virtual hill in “Ancient Rome,” your treadmill deck will tilt up to match. The difference is that instead of a trainer guiding you through Boston, you’re dodging Triceratops or floating past Saturn. It’s a move from “simulated travel” to “immersive cinema,” where the environment dictates the effort but the visuals are pure sci-fi.
Real-World Take
Who is this actually for? As someone who has logged countless hours on indoor trainers, I see the appeal for the “Distract Me” crowd. There are generally two types of indoor runners: those who obsess over the data (Zone 2 graphs, split times) and those who need to completely disassociate to get through the session.
If you usually prop up an iPad to watch movies, this is a compelling alternative. It’s more immersive than a movie because your body is reacting to the terrain—you feel the hill you are seeing. And it’s less “uncanny” than the avatar-based worlds of Zwift, which can feel like playing a video game rather than training. This sits in a new middle ground: photorealistic(ish) video that feels like a dreamscape. It’s perfect for recovery runs or steady-state cardio where the mental battle is harder than the physical one. You aren’t trying to beat a PR; you’re just trying to survive 30 minutes of cardio without losing your mind.
The Catch
The obvious question—and the one tech skeptics will jump on—is the “uncanny valley.” Generative video has come a long way, but 20 minutes is a long time to stare at an AI hallucination. Will the physics feel off? Will the “Dinosaur Island” flora look consistent, or will a tree morph into a rock as you run past it? Early reports suggest the quality is impressive, but if you’re a purist who craves the grit of real pavement, this might feel too artificial.
Also, currently, there are only five worlds. If you run every day, the novelty of the Solar System might wear off by next Tuesday. “Realms” is a fantastic proof of concept, but unless iFIT can churn these out at the speed of Netflix, it might end up being a fun novelty rather than a daily driver. And, of course, you need an iFIT subscription and compatible hardware to access it—no running on Mars with your basic gym treadmill.
Bottom Line
I’m genuinely curious to try “Sky Garden.” It solves a real problem—indoor boredom—with a novel application of the buzziest tech in the world. If you already have an iFIT machine, it’s a must-try. For everyone else, it’s a fascinating glimpse into a future where our workouts aren’t limited by geography, or even physics.
