SENA
Strava for the gym
What it does
SENA is a social workout tracker built for lifters. Most fitness content is easy to watch but hard to actually use. You see a workout on Instagram, TikTok, YouTube, or from a friend, then it disappears into screenshots, notes, or memory. SENA turns workouts into something you can actually do.

Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
