Inside the Home Fitness Startup That Bet Everything on HarmonyOS

The Problem With Home Exercise Equipment

Every piece of home fitness gear has a secret second life as a clothes rack. The treadmill you bought with grand ambitions? It's holding your laundry now. That's the problem Linjing Manyou, a Chinese startup, set out to solve. They didn't just want to make another machine that people buy and abandon. They wanted to make something people actually want to step on, day after day.

The company's product manager, Zhou Jing, put it bluntly: most people aren't lazy. They want to exercise. But the process is boring, repetitive, and requires a mental push every single time. Traditional treadmills are the worst offenders. You start with good intentions, but soon the monotony wins. Linjing Manyou's answer? Turn walking into a game.

From Treadmill to Interactive Playground

Linjing Manyou isn't a treadmill. It's more like a slow-paced walking machine, with speeds ranging from 1 to 6 kilometers per hour. The key isn't speed—it's immersion. The machine connects to Huawei's smart screens, and your footsteps control what happens on screen. Walk through a 4K scenic trail, and the landscape moves with you. Enter a 3D game like Mythical Adventure, and you dodge obstacles, collect items, and interact with characters using hand gestures.

This isn't just a gimmick. The idea is to make movement feel natural. As Zhou Jing explains, walking and running are the most instinctive ways humans move. We explore the world on foot. So why not explore a virtual world the same way? The device is about 1.2 meters wide, giving you room to shift left and right. That space matters—it lets the game respond to your body, not just your feet.

Pivoting to Family Fitness

Initially, Linjing Manyou targeted office workers and fitness beginners—people who wanted to exercise but couldn't stick with it. But after talking to users and testing at events, the team realized something bigger. Exercise isn't just an individual problem. It's a family problem. Kids need to burn energy. Parents need to stay active. Grandparents need low-impact movement.

So the product shifted from a personal fitness tool to a family activity hub. At HDC 2026, the company's demo booth was a hit. Kids lined up repeatedly to play the games. Older visitors asked about cushioning, stability, and safety. The feedback was clear: this isn't about pushing your limits. It's about making movement easy and enjoyable for everyone.

Why HarmonyOS, Not Just Another TV App

You might think putting an app on Huawei's smart screens is just another distribution channel. But for Linjing Manyou, it was a strategic bet. The team had looked at other TV ecosystems and found them fragmented. Different brands had different capabilities—some had cameras, some didn't. Some had powerful chips, others were weak. For an app that relies on real-time motion tracking and smooth graphics, that inconsistency is a killer.

HarmonyOS offered something different: a unified ecosystem. It's not just about one device. It's about connecting phones, smart screens, wearables, and more. That matters for Linjing Manyou because the product isn't a standalone gadget. It's part of a connected home. The team wanted to build deep integrations, not just a standalone app.

But it wasn't an easy decision. Zhou Jing admitted the internal debate was intense. Committing to HarmonyOS meant ignoring other TV platforms for a while, especially when the ecosystem was still growing. But the potential for seamless integration won them over. And so far, the support has been solid. Huawei provides dedicated developer groups, clear documentation, and responsive feedback channels. That's a big deal for a small team.

The Hard Work Behind 'Feeling Natural'

When you watch someone use Linjing Manyou, it looks effortless. Step, and the screen moves. Sway, and your character dodges. But getting to that point was a series of technical battles.

Gesture Recognition

Early on, the HarmonyOS skeleton recognition SDK was basic—only 2D. The team was used to 3D solutions on Android, which offered better accuracy. In a crowded demo booth, the system would sometimes latch onto a bystander instead of the user. Huawei later introduced a locking mechanism that stabilized target tracking, but it took time and collaboration.

Performance Tuning

Smart TVs aren't as powerful as modern phones. The team's 3D game assets were too heavy for some older Huawei screens. Characters wouldn't even move because the models couldn't render. The solution was a delicate balance: compress the models enough to run smoothly, but not so much that they looked terrible. It's a constant trade-off.

Latency

The connection between the walking machine and the screen used to be Bluetooth, which had noticeable lag. Switching to Huawei's NearLink technology cut that delay dramatically. Now, the response feels instant. That's not a spec sheet detail—it's the difference between feeling connected to the experience and feeling like you're controlling a puppet on a string.

What Users Want Next

At HDC, the second most common question after "Is this just a treadmill?" was "Can I play with others online?" People want social interaction, even when they're working out at home. They want challenges, companionship, and maybe a little friendly competition. Linjing Manyou is listening. Online features and co-op modes are on the roadmap.

They're also planning to integrate with Huawei Health. That means syncing workout data, tracking progress, and eventually offering personalized recommendations. Imagine a grandparent stepping on the machine and getting a suggestion for a gentle 15-minute forest walk. Or a kid getting a fun, high-energy game that matches their fitness level. That's the long-term vision.

The Road Ahead

So, what makes Linjing Manyou different from a treadmill? It's not any single feature. It's the whole philosophy. A treadmill is about running in place. Linjing Manyou is about creating an experience that makes you want to move. It's about connecting your body to a screen, a game, and potentially, to other people.

For now, the app is available on Huawei smart screens, and the team is focused on deepening that integration. The hardware works. The software is getting better. The big question is whether families will keep coming back. The team believes they will, because they're not selling a workout. They're selling a reason to play.

In a world where home fitness usually means a lonely grind, Linjing Manyou is betting that fun wins. And so far, the early signs are promising.
