MuscleBuddy
Your coach that rewrites training & diet as you progress
Most fitness apps just log what you did. MuscleBuddy writes your training and nutrition, then auto-adjusts both from your real progress — and tells you why. Muscle ranks, leaderboards, and evidence-based coaching. Deep free tier, no card required.
Hey Product Hunt 👋 I'm Garrett, I built MuscleBuddy solo.
I got tired of fitness apps that are just fancy spreadsheets — they log what you did but never tell you what to do next. MuscleBuddy is the opposite: it writes each session and your macro targets on deterministic engines (not an LLM guessing), then reactively adjusts them from your real weigh-ins and progression, and explains every change.
A few things I'm proud of:
• The free tier is genuinely deep — logging, auto-progression, macros, muscle ranks, leaderboards, challenges, social. Not a crippled trial.
• It's evidence-based — guidance is grounded in research, not bro-science.
• It's an offline-first PWA, so it works mid-workout with no signal.
• Pro adds AI coaching, contest prep, bloodwork/compound tracking, and wearable-driven recovery.
I'd genuinely love feedback — especially on the auto-adjustment and whether the "why" explanations land. Ask me anything!
the auto-adjust on training and nutrition based on actual progress is honestly the first thing like this that didn't feel like generic logging. also nice that the free tier is actually usable without jumping through hoops
Love the auto-adjustment idea, that's what sets it apart from a spreadsheet. One thing I'd really want is a quick "how am I doing this month" summary at the end of each month, something like a recap showing my strength gains, consistency, and whether nutrition actually lined up with results. Would make the "why" behind adjustments way easier to see at a glance.
