Most fitness apps hand you a PDF and expect you to be the expert. Rabtine doesn't. Meet Rab — an AI gym coach that builds your routine from thousands of options, then rewrites it every month based on how you train. The more you log, the sharper he gets. • Instant swaps when an exercise doesn't fit • First routine in 2 minutes, free, no card • $5/mo vs $200/mo for a human trainer Not a library. Not a tracker. A coach that actually knows you.
