EFFORT
Your weight follows your last set
Sets finished near failure are the ones that build muscle. Reps to spare and it adds load. None left and it holds you there.

How it coaches
VOLUME
Enough sets, never junk sets
Hard sets are counted per muscle each week and capped where more work stops paying you back.
RECOVERY
Trains what is actually ready
Each muscle is tracked for how hard and how recently you hit it, and today's session works around that.
CYCLES
The easy week lands before the wall
Your lighter week is scheduled ahead of the plateau instead of after you have already stalled.
Where the rules come from
Every number comes from research. Where it does not, the app says so.
635studies behind the coaching
A to Devery study graded by how strong it is
233settings taken straight from them
0AI deciding your training
Where the research is thin, or a number comes down to a judgement call, the app tells you. It will not dress up an opinion as a finding.
No chatbot is training you. Your weight, your sets, your rest and your next session come from the studies, every time.

Questions
Do I need to know the jargon?
No. After a set you answer one question: how many more reps you could have done. The rest is plain language.
Does it work without signal?
Yes. Everything saves on your phone first and syncs when you are back online.
Good for beginners?
Yes. You get real weight progression from week one, a form video on every exercise, and starter routines to follow.
What happens to my data?
