Show HN: I built an app to calculate body type and generate AI fitness plans

Hey Hacker News, I'm excited to share a project I've been passionately building. It started from a personal frustration: most fitness and nutrition advice online is generic. I wanted a tool that could provide a truly personalized starting point based on my specific body composition and goals. That’s why I created https://mybodytype.net. It's more than just a plan generator; it's a suite of tools to guide your fitness journey. Here’s a breakdown of the features: Body Type Calculator (Free): This is the entry point. Answer a few questions, and it determines your body type (e.g., ectomorph, mesomorph, endomorph). This result informs the recommendations that follow. Progress Tracker (Free): A robust tool to log your workouts, measurements, and track your progress over time. Staying consistent is key, and this helps you do it. AI Meal Plan Generator (Premium): Based on your body type, goals (weight loss, muscle gain), and dietary preferences, it generates a complete daily meal plan with macros and recipes. AI Workout Plan Generator (Premium): Creates a structured, weekly workout schedule tailored to your experience level and goals, complete with specific exercises. PDF Export (Premium): For those who like to have a physical copy or save their plans offline, you can export your meal and workout plans to PDF. Style Recommendations (Coming Soon/Premium): A feature I'm currently working on to provide clothing and style recommendations that best fit your body type. The "Why": My goal is to bridge the gap between generic advice and expensive personal coaching. This app provides a data-driven, scientific foundation for anyone serious about improving their health, taking the guesswork out of the initial, most difficult steps. Tech Stack: For the tech-curious, the entire application is built on Next.js (App Router) with TypeScript. The backend logic is handled by Next.js API routes, and the frontend is built with React, Tailwind CSS, and Shadcn UI components. I've focused on keeping it fast and server-rendered wherever possible. Feedback & A Hacker News Offer: I'm launching today and would be incredibly grateful for your honest feedback.
