Code practice for executives.
Technical executives who stopped reading code lose the read on whether engineering's AI-built systems are actually sound.
Is code practice useful for executives?
Plenty of senior leaders came up technical and now never read a line. The codebase runs through AI assistants, the architecture decisions arrive as a summary, and a CTO or technical founder ends up steering systems they can no longer read. Anthropic's 2026 study found AI assistance reduced new-skill formation for developers; the same dynamic, scaled up, leaves a technical executive unable to follow the logic their teams now generate. Losing the ability to read code is losing a sense for whether the answers you are given are sound.
A code rep, for executives
A code rep shows you a short, unfamiliar function and asks what it returns for a given input, no running it. You have to trace the logic by hand, branch by branch. That is the exact muscle a technical leader needs when an engineer walks them through an AI-generated change and they want to actually follow it, not just trust the summary.

How the habit fits a executives day
For the technically-minded executive, a single trace-this-function rep in a morning Set keeps the reading-code muscle from going fully cold, so when an architecture review or an AI-generated pull request comes across your desk you can still follow the logic rather than nodding along.
Questions executives ask
- I am an executive, not an engineer anymore. Is code practice relevant? Only if you came up technical and still want to follow engineering decisions. If you never read code, skip this skill; the other five fit you better. For a CTO or technical founder, it keeps the read-and-trace-logic act available so AI-generated work is reviewable, not just trusted.
- Will code reps keep my technical skills current? No broad claim there. A code rep is practice at one act, tracing what a small piece of code does by reading it. Anthropic's 2026 work found AI assistance cut new-skill formation for developers; the reps keep the reading-logic act in use, nothing more.
- Do I need to know a specific language? The reps use short, readable snippets aimed at logic rather than syntax trivia, so general programming literacy is enough. The point is following what the code does, not memorizing a language. If you have not touched code in years, the reading and reasoning skills are a better fit.

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.
