Apple Watch GymKit allows you to get accurate and detailed workout data, now live at a New York gym

Apple has now made it super easy to get accurate and detailed stats from your gym workouts on treadmills and ellipticals using only the Apple Watch. The feature comes as part of the Apple Watch's GymKit and has so far been rolled out only in a few gyms in Australia and London, but now it has made its debut at the Life Time Athletic at Sky gym located at 605 West 42nd Street in New York.

A wider roll-out is expected in 2018 at other premium gyms such as the Equinox chain from New York.

GymKit came as a new Apple Watch feature bundled with the watchOS 4.1 update that came in October, but for a short while it was a feature with no real-world support.

GymKit is made to give more accurate indoor workout stats as it syncs distance, speed, weight, floors climbed, heart rate, and estimated calories burned with training equipment. It's as simple as tapping your Apple watch against a compatible piece of gym equipment like a treadmill, and it works using NFC technology to transfer data wirelessly.

Once you tap your watch and it connects to a treadmill, the treadmill will mirror what your watch usually shows. It's a bit like CarPlay, just for workouts. The workout data is then passed on to your watch and phone, and you can see it in your activity as a workout.
