I went behind the scenes to see how Huawei’s Health Lab is shaping the future of fitness watches

Huddled into the back of an industrial park to the west of Helsinki, Finland, sits Huawei’s latest Health Lab, overlooking the Lauttasaari strait. From the outside, it’s quite an unassuming structure, looking like your standard, square, brick building that might have once been modern but no longer is. But peel back the exterior and you’ll find a laboratory packed with the latest equipment for testing and measuring sports, a data-gathering hub, using sport science to boost the company’s wearables, with the aim of making the next smartwatch even better for activity tracking.
