Separate rules from session work
Keep the program rules clear: days, exercises, sets, reps, intensities, and progression decisions.
Then convert the current session into the few numbers you need today: target load, warm-up plan, and logging path.
A spreadsheet can hold the whole system, but the session should not require you to re-derive the system between sets.
Keep the math visible
Do not hide formula assumptions. If a percentage, e1RM, or RPE estimate drives the session, make the calculation easy to inspect.
Example: if a sheet says squat 5 x 5 at 75% of a 160 kg training max, the useful session number is 120 kg. From there, you still need plates, warm-ups, and a place to record what happened.
Convert only what helps execution
Do not rebuild every spreadsheet cell inside the app on day one. Start with the routine structure, the loading rule you actually use, and the progression decision you need after the session.
If the sheet mixes kg and lb, normalize units before entering targets. If it uses exact percentages that do not fit your equipment, round intentionally and write down why.
Use Protocol for execution
Use this guide as a manual planning step rather than a file converter. Start by building the routine in Protocol, then run sessions from the app.
The calculator pages help with the math around the routine. Protocol is where the routine becomes something you can start, follow, log, and bring back next week.
