ℹ️ About

Prison Deck + Circuit is a free, open‑source workout web app designed for home training without any equipment. It combines two powerful training methods to keep your workouts varied, challenging, and effective.

🃏 Deck Mode – turns a standard deck of 52 cards into a full‑body workout. Each suit maps to a fundamental bodyweight exercise: Push‑ups (♥️), Pull‑ups (♠️), Squats (♦️), and Crunches (♣️). The rank of each card (2 to 10, J, Q, K, A) determines the number of reps. Just draw a card, perform the exercise, and move to the next – completing the entire deck gives you a balanced, high‑volume session that builds strength and endurance.

🔄 Circuit Mode – lets you build your own circuit from a custom exercise base. Set your maximum repetition number for each exercise, and the app automatically creates a pyramid of 5 sets (100% → 80% → 60% → 50% → 50% of your max). The built‑in 2‑minute rest timer with sound and vibration alerts keeps you on track. This approach is proven to increase muscular endurance and cardiovascular fitness.

🎧 Lofi Radio – stay focused with a continuous stream of chill beats to relax and study to. The radio plays in the background without interrupting your workout flow.

📲 Progressive Web App (PWA) – you can install this app on your phone (Android, iOS, or desktop) and use it offline. All your workout history, custom exercises, and programs are automatically saved locally in your browser. No account, no server, no ads – just pure training.

💪 Benefits – improve functional strength, burn calories, increase mobility, and break the monotony of traditional workouts. Whether you're a beginner or an advanced athlete, the random nature of the deck and the customizable circuit keep every session fresh and challenging.

🔧 Fully Customizable – you can rename exercises, add new ones, create and save your own programs, and track your progress daily. All data is stored locally – you are in full control.

🌐 Open Source & Free – this project is maintained by the community and will always remain free. If you find it useful, consider supporting the development with a small Bitcoin donation – every contribution helps keep the project alive and ad‑free.
