Wearable Integration: Garmin, Whoop, Oura, Apple Watch

Wearable integration in coaching platforms is the single most over-promised feature in the category. Every vendor claims integration with Garmin, Whoop, Oura, and Apple Watch. Real integration depth varies from "we pull steps and heart rate" to "we ingest structured workouts, recovery scores, and sleep stages and route them back to your programming view." Those are different products.

Reviews here will test what each platform actually pulls, how often the sync runs, whether it survives a wearable firmware update, and what the coaching workflow looks like once the data is in. Garmin Connect IQ depth, Whoop API breadth, Oura recovery handling, Apple Health round-tripping.
