Use distinct routine names and actual set results to keep a push pull legs record understandable.
Keep session identity
Use names such as Push, Pull and Legs for the plan you already follow. A split name alone does not specify exercise selection, frequency or progression.
Record substitutions
If a session uses a different exercise or machine, preserve that detail. Otherwise the next review may compare different tasks.
Compare within the same session type
Look at comparable exercises across matching sessions. A higher combined weekly total is not direct evidence of muscle growth or a better split.
Keep the split separate from the calendar
Push, pull and legs are session labels; they do not establish how often someone should train. If your chosen plan rotates those sessions, name routines so the next intended session is recognizable even after a missed day. Record the session on the date it actually happened. Moving a planned Tuesday workout to Wednesday should not produce a fictional Tuesday completion in the history.
Log exceptions inside the right session
If one pull-session exercise is replaced because equipment is unavailable, record the replacement under its own identity and note the substitution. Keep actual repetition counts when the last set differs from the plan. When reviewing, compare the same session type and movement variations rather than combining every day into one undifferentiated total. This walkthrough supports recordkeeping; it does not select exercises, prescribe frequency or automatically manage progression.
