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. Track your lifts, build reusable templates, post completed sessions, copy workouts from friends and creators and see your progress over time. Stop watching workouts. Start doing them.
