Your rules
It trains the way you want to train.
Set your rep ranges, your reserve, your progression and the lifts that matter. Or say it in your own words. Vasbyt reads the rule back, then applies it to every set, every program and every report.
Where you set them
Fill in the form, or just say it.
Your training profile is where the rules live. Answer as much or as little as you like, in the form or in plain writing, and Vasbyt works to what you gave it instead of a one-size-fits-all template.
- Set your preferences. Your focus, the lifts that matter most, your style, how hard you like to push, and anything you need to work around.
- In your own words. Write notes like “I add weight when I hit the top of my rep range two sessions running.” Vasbyt reads them when it drafts your program, and the ones it can measure you can turn into graded rules.
- It reads the rule back. Every rule becomes one plain sentence, like “Working sets should finish around 2 reps in reserve.” That sentence is what gets applied, and what your sessions are graded against.
- Grouped by what counts. Each rule is tagged by how much weight it should carry, so a firm principle outweighs a mild preference.
The next set
Your rules, applied to your numbers.
Right where you log, a weight, a rep target and how much to leave in the tank, worked out from your own history under your own rules. A starting point, not an order.
Anatomy of a suggestion
A number, a reserve, and the maths.
What to aim for
A weight and a rep count for the set in front of you.

The maths behind it
Tap it and the card shows what in your last sets led to the number.

It all comes from your own logbook and your own rules. The more you log, the closer it gets.
Built around you
It learns how your body actually responds.
Two lifters with the same rules get different numbers. Vasbyt goes off your own logged sets, not some average gym-goer.
- It knows how you tire out. Vasbyt watches how your reps hold up set to set, lift by lift, and shapes the numbers around the way you fade.
- Tell it how you feel. Log soreness, energy, and sleep with a check-in, and your coach report on the Progress page reads them alongside your lifts.
Mid-session help
Stuck mid-set? Just ask.
Not sure about your form?
Open Form Tips on any exercise, say what's hurting or feeling off, and get advice written for that lift and that exact problem.
Machine taken? Swap it.
Rack busy, machine missing, shoulder cranky? Ask for a swap and get three solid replacements for the same muscle that fit the rest of the day's session.
Nothing gets lost
A swapped exercise remembers what it stood in for, so your session keeps its shape and your history stays honest.
The program builder
Don't know where to start? Let it draft one.
Build your own training days, or say what you're after and let Vasbyt draft a program from your rules. You keep it, edit it, or throw it out. Either way, every set inside it still follows the same rules.
- Say what you want, get a plan. Your goals, how many days a week you can train, the split you like, and your rules all go in. A program comes out.
- Built from your rules. Your rep ranges, your effort target, and the lifts you have ruled out shape every program it drafts, and each number says which rule set it.
- No plan? No problem. Skip the program, just log what you did, and your rules still apply to every set.
It reads your training so you don't have to.
Behind the scenes, Vasbyt goes through everything you've logged: it catches lifts that have stalled and points out muscles where you're putting in the work but the big lifts aren't budging. You see all of it on the Progress page, in the Strength, Volume, and Coach views, and your coach report reads it too.
