Buena
Your form. Every rep. Every set. Perfected.
The AI coach that sees what you can’t — and programs what you need.
Most people lift alone. No one watches their form. No one adjusts their program. They guess their way through every session — and wonder why they plateau.
Every angle.
Every rep.
Buena tracks your joint positions with biomechanical precision. It catches knee cave before you feel it. It flags back rounding before it becomes an injury. Real-time voice cues tell you exactly what to fix — mid-set, when it matters.
- Joint angle tracking
- Real-time voice correction
- Rep-by-rep form scoring
- Voice countdown
It knows where
you’re going.
Buena tracks every set, every rep, every pound. It knows how hard you struggled on that last rep of bench press. It reads your recovery signals. Then it programs tomorrow — automatically. Progressive overload when you’re ready. Deload when you’re not.
- Automatic progressive overload
- HRV-based intensity adjust
- Smart exercise rotation
- Goal-specific programming
