Anime Workout API: Why do a bench press when you can do a Spirit Bomb Press?

Hey PH! I'm JP. I built this because I was prototyping a fitness app and hit the same wall every developer hits — the workout content. Building a proper exercise database with periodization logic, substitution maps, and progression rules is months of work. Most fitness APIs just give you a list of exercises. This one gives you a full program with phased progression. The anime theming started as a personal motivation hack. Telling yourself to do 5x8 bench press at RPE 6.5 is boring. Telling yourself to do 5x8 "Spirit Bomb Press" while Goku says "I am the hope of the universe!" is genuinely more fun. A few things I'm proud of: - The periodization is real — accumulation, intensification, deload, realization with RPE ramping - Every exercise has a substitution map, so if someone has no barbell or a bad shoulder, you can swap instantly - The response schema is designed to be UI-flexible — works for card layouts, list views, calendar views - It's stateless. Your request goes in, a program comes out. Nothing stored. Would love your feedback, especially from anyone building fitness or wellness products.
