Build Garmin Strength Workouts — Free Tool
Garmin Connect's built-in workout builder is slow and requires multiple page loads. This tool lets you design a full strength session in under a minute and download a JSON file that imports directly — no account needed, no data sent to a server.
What is a Garmin workout JSON file?
Garmin Connect uses a specific JSON schema to describe structured workouts. Each exercise is a RepeatGroupDTO containing ExecutableStepDTO objects for the active set and rest period. The file specifies exercise category, name, rep count or duration, weight, and rest time per set.
Supported Garmin devices
Imported strength workouts work on Garmin Forerunner 955/965, Fenix 7/8, Epix (Gen 2), Instinct 2, and all other devices with the Garmin strength training activity profile. Once imported, the workout is pushed to your watch via Garmin Connect Mobile or the Connect IQ store sync.
Weight tracking
If you enter a weight value, it is included in the workout step and will display on your watch during the set. Garmin also logs the weight in your activity history, making it easy to track progressive overload over time.
