Use gym equipment with Apple Watch
Your Apple Watch can pair and sync data with compatible cardio equipment such as treadmills, ellipticals, indoor bikes, and more, providing you with more accurate information about your workout.
Pair your Apple Watch with gym equipment
Check if the equipment is compatible—youʼll see “Connects with Apple Watch” or “Connect with Apple Watch” on the equipment.
Make sure your watch is set to detect gym equipment—open the Apple Watch app on your iPhone, tap My Watch, tap Workout, then turn on Detect Gym Equipment.
Hold your Apple Watch within a few centimeters of the contactless reader on the gym equipment, with the display facing the reader.
A gentle tap and beep confirm that your Apple Watch is paired.
If Detect Gym Equipment is off in Settings 
> General > Workout, open the Workout app 
, then hold your Apple Watch near the contactless reader on the gym equipment, with the display facing the reader.
Start and end a workout
Press Start on the gym equipment to begin. Press Stop on the equipment to end the workout.
When you end your workout, data from the equipment appears in the workout summary in the Activity app on your Apple Watch and iPhone.
