Reasoning practice for the before deep work.
A reasoning rep before the block warms up the build-the-argument-yourself muscle, so the deep work starts with your logic, not the model's framing.
How do I fit reasoning practice into the before deep work?
The hardest part of a deep-work block is often the first reasoning move: framing the problem, weighing two options, deciding what follows from what. When that move is handed to an AI, you get a framing to react to instead of one you built. A reasoning rep first rehearses constructing the chain yourself: a short deduction, a comparison, a counterfactual. Seven minutes of that and you enter the block ready to lay out your own logic before asking a model to check it.
A reasoning rep for the before deep work
A rep gives three premises and asks which conclusion holds. You notice the tempting conclusion overreaches and pick the narrower one that actually follows. An hour later, framing the trade-off the block is really about, you sketch the options yourself before opening the AI, instead of letting it hand you the frame.
What reasoning practice covers in the daily Set
- Logic
- Deduction
- Comparison
- Decision-making
- Counterfactual thinking

Habit anchor for the before deep work
Schedule the Set at the head of the deep-work block. The deduction and comparison reps warm up the argument-building muscle the block leans on, so the focus session opens with you constructing the reasoning rather than reacting to a generated frame. The seven minutes get your own logic moving first.
Common questions
- Why reason through puzzles before a block where I could just ask the AI? Because asking first means you react to the model's framing instead of building your own. A short deduction or comparison rep warms up the act of constructing an argument, so you enter the block laying out your own logic first and using the AI to pressure-test it, not to do the thinking.
- Does this make my decisions better? We do not claim that. The rep keeps deduction, comparison, and counterfactual thinking in regular use. The narrow point is that offloading the framing to AI makes it easy to stop building arguments yourself; a daily rep keeps that act in practice before the block where it matters most.
- What does a reasoning rep involve? Short logic moves: which conclusion follows, which option wins under a constraint, what changes if one fact flips. No long problems. It is a seven-minute on-ramp built to switch on the build-your-own-argument reflex before the focus block, not to settle the day's actual decision.

Not brain training. Brain exercise.
Senwitt is a daily brain exercise app, not a brain training program. We do not claim to improve general cognition, prevent cognitive decline, or treat any condition. Independent scientific consensus — the 2014 Stanford Center on Longevity / Max Planck Institute statement signed by 70 neuroscientists, the 2016 Simons et al. review in Psychological Science in the Public Interest, and the FTC's 2016 settlement with Lumos Labs — has concluded that “brain training” claims are not supported by the evidence. Senwitt is built on a different premise: skills you actively practice get sharper; skills you stop practicing fade.
