This app is built from PeakStrength's 4-day and 5-day athletic split templates. Each training day lists categories (e.g. Technical Coordination, Absolute Strength, Accessories, Mobility). Neither article prescribes fixed sets/reps — you pick exercise(s) from each category and log your own weight/reps/sets as you go.
General guideline from the articles: pick 1 technical coordination move, 1–2 absolute strength moves, 3–4 accessory movements (pair them as contrasting supersets), and 4–5 mobility drills to close the session (~10–15 min).
Use the toggle top-right to switch between the 4-day and 5-day split at any time — your history and PRs carry over either way.
The day dropdown on Today defaults to the next day in your rotation, but you can jump to any day if your schedule shifts.
Everything is stored only on this device (localStorage) — nothing is sent anywhere. Add this page to your Home Screen (Share → Add to Home Screen) to use it like an app.
