Open Strength-Training Data Bridge for Garmin Owners After Garmin Cut Hevy and Other Third-Party Strength Apps Off at the API Level
Garmin has restricted third-party strength app integration at the API level, blocking apps like Hevy from pushing completed workout data back into Garmin Connect, while Garmin builds its own native (and paywalled, via Connect+) strength ecosystem. Strength athletes who already use Hevy, Strong, or HEVY-class apps for actual reps/sets logging now have no way to get that work counted in their Garmin training load. The opportunity is an explicit data bridge that takes strength sessions from popular logging apps and rewrites them into Garmin-compatible activities via FIT file injection or sync workarounds.
The trick is FIT file injection via the Garmin Connect web import path, which Garmin hasn't bothered to lock down because it's used by triathlon coaching tools. Build it as a coach-tool-class product, not a consumer Hevy plugin, and Garmin is much less likely to swing the API hammer at you.

Garmin is using API restrictions to bully users into Connect+. Users would rather pay a one-time fee to a third party that brokers their existing strength app into a Garmin-acceptable format than be funneled into Garmin's worse first-party UI.
