Garmin weekly strength coach

Auto-adjusts your Garmin strength workouts every week based on how you actually trained

Problem

Garmin users want to strength train, but watch plans are static—they don't adapt to last week's completion, fatigue, or progress. Users either manually edit or give up, breaking training continuity.

Solution

Connects to Garmin Connect, reads last week's workout completion, and generates next week's strength sessions using progressive overload rules, syncing to the watch calendar. Manual override and notes supported.

Users

Fitness enthusiasts who strength train with Garmin watches

MVP

OAuth connect to Garmin Connect and read activities; simple progressive rules based on completion rate and RPE to generate next week's workouts; sync to Garmin calendar; web view with manual adjustments

Revenue

Subscription $5/month or $49/year; free tier limited to 4 weeks of history

Why now

Garmin's API is open and strength training users are growing, but official plans aren't personalized; a solo dev can differentiate with simple rules and no hardware
