Hey Product Hunt 👋 I'm Dimas, an AI/ML engineer, not a fitness influencer. I've trained for years (gym, capoeira, surf), but every workout app I tried either handed me a generic template or hid the actual reasoning behind a paywall. None could answer the one question I kept asking: why this exercise, why now? So my co-founder Euler and I built SelfShape AI. It builds your plan from your real routine and equipment, adapts every session as you progress, and, the part I care most about, explains the reasoning behind each decision, grounded in modern exercise science (ACSM) and a 260+ exercise taxonomy. We went Brazil-first: the musculação culture here is massive and badly underserved by good software. Now we're opening it up. One thing I'd genuinely love feedback on: does surfacing the "why" behind every decision make you trust the plan more, or do you just want it to tell you what to do? I keep going back and forth on how much reasoning to expose. Happy to dig into anything: the product, the exercise-science model, or the engineering behind it. Thanks for checking it out 🙏
