Prompt
Here is my powerlifting data from the last three months, covering volume, intensity, and RPE for squat, bench, and deadlift. Please analyze these logs for peak performance windows, recovery requirements, and technique or load plateaus. I need the output formatted with a results section and a distinct section for recommended training adjustments.
