Hey Product Hunt 👋

I'm Bruno, the maker of Rabtine.

Honestly, I built this for myself first.

I was tired of fitness apps that hand you a blank canvas and expect you to fill it in. They assume you already know which exercises hit which muscle, how many sets, what rep range, when to deload, what to swap when something doesn't fit. Most of us don't. And the ones who do still don't want to spend Sunday night programming next week's training.

The other option is a personal trainer. $150–200/month. Scheduling.
Driving. Cancellations. Not happening.

What I actually wanted was simple:
• A plan built for me — my goals, my equipment, my limits.
• Continuity. Something that evolves with me month after month, not a 4-week loop on repeat.
• A real guarantee of progress — not a feeling, not a chart of random numbers.
• To always know exactly what to do today, and why.

So I built Rab.

Rab is an AI gym coach that builds your routine from thousands of possible combinations — not templates — based on your goals, experience, equipment, and limits. Then he rewrites it every month based on how you actually train. The more you log, the sharper he gets.

A few things we did differently:
• First personalized routine in under 2 minutes. Free. No credit card, no paywall to see what you get.
• Instant swaps without breaking the plan — no barbell today? shoulder acting up? Rab adjusts on the spot.
• Pro is $5/month. Same level of personalization as a trainer, minus the scheduling and the $200 invoice.

Rab isn't a workout library or a tracker. He's a coach that actually knows you.

Would love your feedback — especially from anyone who's bounced off fitness apps before. What did Rab get right? What's missing?
