Session notes are one of the most underutilized tools in professional training. Most trainers keep some form of record — loads used, exercises completed, maybe a general comment about how the session went. What most session notes don't capture is the information that would actually change a future programming decision: what the client said, what you observed, what surprised you, and what you're watching. The difference between notes that inform future programming and notes that just fill a record is specificity.
What session notes are actually for
Session notes serve three distinct purposes, and understanding all three helps clarify what needs to be in them. The first is performance tracking — recording the loads, sets, and reps completed so you have an accurate baseline for progressive overload decisions in future sessions. This is the most commonly captured element and the most straightforward.
The second is clinical observation — recording what you noticed about the client's movement quality, energy level, technique patterns, and any symptoms or complaints they mentioned. This is the information that a future-you will need when making a programming change six weeks from now, and it's the most commonly missed element in session notes.
The third is relational context — brief notes on what was happening in the client's life during the session. The stressful week at work that explained the flat energy. The mention of a wedding in three months that clarified the body composition motivation. The comment about a previous injury that flared up last weekend. These aren't performance data, but they're the context that makes performance data interpretable.
What to record for performance tracking
Record exercises, sets, reps completed, and loads used. Record RPE for primary movements where RPE-based loading is in use. Note any sets where the client failed to complete the prescribed reps, and record the reason if known — was it load selection, fatigue, or a technique breakdown? This distinction matters for the next programming decision.
If you're using benchmark movements to track progress, record these consistently and in enough detail to be comparable across sessions. A squat recorded as "squats — good" is not comparable to anything. A squat recorded as "back squat, 80kg, 4x5, RPE 7, clean technique" is a data point that compounds in value over time.
What to record for clinical observation
Note any technique issues you observed and the cue or correction you used. Note any movements the client found unusually difficult or unusually easy relative to expectations. Note any complaints about discomfort or pain — the location, the movement that provoked it, and whether it resolved during the session or persisted. Note any significant changes in movement quality compared to previous sessions, in either direction.
These observations don't need to be lengthy. A sentence is enough: "Hip hinging technique breaking down at higher loads — cued posterior weight shift, improved. Watch in next session." That sentence is more useful than a paragraph of general commentary.
What to record for relational context
Brief notes on relevant life context are worth keeping. Not a diary of the client's personal life, but the specific details that affected training and that might be relevant in future weeks. "Mentioned very poor sleep this week — explains flat performance. Watch recovery trend." "Brought up body composition goal more specifically — want to discuss program emphasis at next block transition." These notes make future you a better coach than present you can be without them.
How to build the note-taking habit
The best session note is the one that actually gets written. A thirty-second record of the most important things from a session, written immediately after the client leaves, is more valuable than a comprehensive note you intended to write later and never did. Keep the format simple enough to complete in under two minutes. The detail that matters is specificity about the things that will inform future decisions — not comprehensiveness for its own sake.
