+## Phase Implementation Details
+
+### Phase 1: Setup & Core Structure
+- [ ] Initialize Go module: `go mod init github.com/sstent/go-garminconnect`
+- [ ] Create directory structure
+- [ ] Set up CI/CD pipeline
+- [ ] Create Makefile with build/test targets
+- [ ] Add basic README with project overview
+
+### Phase 2: Authentication Implementation
+- [ ] Implement OAuth2 authentication flow
+- [ ] Create token storage interface
+- [ ] Implement session management with auto-refresh
+- [ ] Handle MFA authentication
+- [ ] Test against sandbox environment
+
+### Phase 3: API Client Core
+- [ ] Create Client struct with configuration
+- [ ] Implement generic request handler
+- [ ] Add automatic token refresh
+- [ ] Implement rate limiting
+- [ ] Set up connection pooling
+- [ ] Create response parsing utilities
+
+### Phase 4: Endpoint Implementation
+#### Health Data Endpoints
+- [ ] Body composition
+- [ ] Sleep data
+- [ ] Heart rate/HRV/RHR
+- [ ] Stress data
+- [ ] Body battery
+
+#### Activity Endpoints
+- [ ] Activity list/search
+- [ ] Activity details
+- [ ] Activity upload/download
+- [ ] Gear management
+
+#### User Data Endpoints
+- [ ] User summary
+- [ ] Daily stats
+- [ ] Goals/badges
+
+### Phase 5: FIT Handling
+- [ ] Port FIT encoder from Python
+- [ ] Implement weight composition encoding
+- [ ] Create streaming FIT encoder
+- [ ] Add FIT parser
+
+### Phase 6: Testing & Quality
+- [ ] Table-driven endpoint tests
+- [ ] Mock server implementation
+- [ ] FIT golden file tests
+- [ ] Performance benchmarks
+- [ ] Static analysis integration
+
+### Phase 7: Documentation & Examples
+- [ ] Complete GoDoc coverage
+- [ ] Create usage examples
