Summarise a Month of Workout Logs Into What Actually Worked

The first month of a workout log is mostly noise unless something reads it properly. This counts what actually happened against what was planned, finds which session type had the best attendance, names one real sign of progress, and suggests one realistic change for next month rather than a bigger overhaul.

**Summarise the month:**
1. Count how many sessions actually happened against how many were planned or intended
2. Identify which type of session (or time of day) had the best attendance and which had the worst
3. Name one clear sign of progress in the numbers, even if small
4. Suggest one realistic change for next month based on the pattern, not a bigger overall commitment

- Sessions completed vs intended: one line
- Best and worst attended session type: one sentence each
- Sign of progress: one sentence
- One change for next month: one sentence
- If the log is incomplete, state that plainly before the summary
