The basics
A pipeline is a flow: Source → Boosters → Target.
- Source — Where your activity comes from (Hevy, Strava, Fitbit, etc.)
- Boosters — Transformations applied to the activity (summaries, heatmaps, heart rate, etc.)
- Target — Where the boosted activity goes (Strava, Showcase, TrainingPeaks, etc.)
One source per pipeline. Multiple boosters. One or more targets.
Example
Hevy → Strava with muscle heatmaps
- Source: Hevy (your strength workouts)
- Boosters: Workout Summary, Muscle Heatmap
- Target: Strava
When you complete a workout in Hevy, FitGlue receives it, adds the summary and heatmap, and uploads the enhanced activity to Strava.
Why pipelines?
Your fitness data lives in many places. FitGlue unifies it by letting you define exactly how data flows and what gets added along the way. No manual copying, no duplicate entry—just automatic transformation.
