AI Coach
Your next set, called with reasons.
Vasbyt reads your training history and proposes the next weight, reps, and target RIR. And it tells you why, not just a number.
The suggestion moment
An AI goal card appears at your set.
Right where you log, Vasbyt lays out the target load, reps, and RIR, with the decision, the why, and a cue to lift by. Watch it land:
Anatomy of a suggestion
Three parts, every time.
The call itself
A concrete target, load, reps, and RIR, for the set in front of you.
Holding at 90 lbs for 5 reps. RIR 1 last time means you were near failure.The call from the goal card above
The reasoning
What in your history led to the call, and what today's set will prove either way.
Same load repeated, with a goal of RIR 2. If it's there, you've adapted. If not, that's normal.The reasoning from the goal card above
How to execute
A focus for the set itself, so the target translates into clean reps.
Control the tempo, don't grind. Stop with 2 clean reps left.The cue from the goal card above
All of it is computed from your own logbook: the reps, loads, and RIR you've recorded for that lift, set against how you've responded before. More history, sharper calls.
Built around you
It learns what you respond best to.
Two lifters with the same numbers get different advice. Vasbyt models you from your own logged sets, not from a population average.
- A personal fatigue profile. Vasbyt studies how your reps actually hold up across sets at each RIR, lift by lift, and shapes targets to the way you fatigue.
- Check-ins steer the load. Log soreness, energy, and sleep, and the advice adjusts. On a rough week the coach tells you to back off instead of pushing.
- It knows when to ease up. When fatigue keeps showing in your numbers, the call is lighter work, not grinding through it.
Your rules
Steered by your training principles.
Tell Vasbyt how you train, and the AI's advice follows it: your approach applied to your numbers, instead of a generic template.
- Structured principles. Focus, priority lifts, training style, intensity preference, volume emphasis, limitations.
- Your own words. Write annotations like “I add weight when I hit the top of my rep range two sessions running,” and the coach honors them.
- Completeness meter. See how much steer you've given, and add more whenever you like.
Mid-session help
A coach you can ask things.
Form tips, on demand
Open Form Tips on any exercise, describe the pain, discomfort, or form concern, and get AI advice written for that lift and that problem.
Smart substitutions
Rack taken, machine missing, shoulder cranky? Ask for a swap and get three ranked substitutes that respect your training principles, the rest of the day's session, and any limitations you've noted.
Swaps keep the thread
A substituted exercise carries the context of what it replaced, so the session keeps its shape and the history stays honest.
The program builder
Build it yourself, or have it built.
Assemble your own training days, or tell the AI what you're after and let it design the program around you. The coach then works inside whatever plan you run.
- Describe it, get it. Your goals, how many days you train, the split you like, and your principles go in. A program comes out.
- Informed by your progress. The builder favors exercises that have actually driven your gains and flags stalled lifts for variation.
- Freestyle still counts. Skip the plan, log what you did, and the history feeds the same coach.
It sifts your data like a coach would.
Behind the suggestions, Vasbyt is reading everything you've logged: it spots lifts that have stalled, flags muscles where the volume is landing but the priority lifts aren't moving, and feeds those findings into the AI's analysis and program design. You see the results on the Progress page, in the Strength, Volume, and Coach views.
