The foundation
At its core, a logbook.
Log exercises, sets, reps, weight, and RIR in a couple of taps. Fast enough to use mid-session, between sets, without breaking the work.
How Vasbyt works
Start with a logbook.
End up with a coach.
Five things Vasbyt does, in the order they happen to your training. Every screen below is the real app.
The coach
Then the AI coaches you.
AI-navigated progressive overload that adapts to you, not to an average. Vasbyt builds a personal fatigue profile from your own sets, learns how your reps hold up at each RIR and what you respond best to, then proposes the next weight, reps, and target RIR with the reasoning behind the call. When equipment or a tweak gets in the way, it suggests smart exercise substitutions too.

The payoff
Progress, read like a coach reads it.
Vasbyt sifts every set you have ever logged into coach-grade analysis. Strength, Volume, and Coach views chart your estimated 1RM and working volume, PRs are detected automatically, and AI findings flag stalls and dips before they cost you a block.
The structure
Programs, built either way.
Build your training blocks yourself in the program builder, or tell the AI your goals, your schedule, and how you like to train, and it designs one around the exercises that have actually driven your progress.
The crew
A circle of support.
Post real workout cards to a feed of friends, react to their sessions, and collect awards. An uplifting circle that keeps you motivated and keeps the work visible.
That's the whole arc, from the first set you log to a coach that knows how you train.
