Workout Next is a modern, privacy-focused workout timer and exercise companion built with Next.js. It provides a streamlined interface for following structured workout routines, including warm-ups, core exercises, and cool-downs. The application is designed as a Progressive Web App (PWA), ensuring it remains accessible and functional even on the go.

• Structured Routines: Seamlessly transition between warm-up, workout, and cool-down phases.
• Visual Guidance: Integrated exercise images and timers to keep you on track.
• Privacy First: Data is stored locally in your browser; no sign-ups or cloud sync required.
• PWA Support: Installable on mobile devices for a native-like experience.

Each workout session is dynamically generated to provide a balanced and effective routine:

• Selection: 5 unique mobility exercises.
• Timing: 30 seconds per exercise.

The core phase is organized into repetitive blocks to build intensity:

• Block Logic: Each block consists of 3 or 4 random exercises.
• Pattern:
  • Round 1: All exercises in the block (30s each).
  • Rest: 30 seconds.
  • Round 2: Repeat the same exercises (30s each).
• Transition: 30-second rest between different blocks.

• Selection: 5 unique stretching exercises.
• Timing: 30 seconds per exercise.

This application is built entirely using Gemini through an agentic development process, showcasing the power of AI-driven software engineering.
