Track Workouts by Muscle Group and Spot What You're Skipping
A free Notion tracker organising every workout by body part, so you can log reps, follow progress and see which muscle groups you've been quietly skipping.
Everybody trains what they enjoy. It's not a discipline failure, it's just that the sessions you look forward to get done and the ones you don't get postponed, and the imbalance builds so gradually that no single week ever looks wrong.
The free Muscle Group Exercise Tracker organises every workout by body part, which makes the pattern visible in about ten seconds.
Volume per muscle group is the real number
Counting sessions tells you how often you trained. Counting sets per muscle group over a fortnight tells you what you actually trained, and the two are frequently very different. Most people who check for the first time find one group at roughly half the volume of the rest, and it's rarely the one they'd have guessed.
- Chest and shoulders, usually well covered.
- Back, often under-trained relative to pressing, which shows up in posture before it shows up anywhere else.
- Legs, the most commonly skipped and the most consequential.
- Arms, usually over-represented relative to their contribution.
- Core, typically an afterthought at the end of a session, if at all.
Why imbalance matters beyond aesthetics
A strength difference between opposing muscle groups is one of the more reliable predictors of the kind of injury that ends a training block. Pulling volume that lags well behind pushing volume is the classic example. Tracking by group catches this months before anything hurts, which is the only useful time to catch it.
The muscle group you skip doesn't get weaker in isolation. It gets weaker relative to the ones you don't skip.
Rotate what's behind to the front
The simplest correction is ordering. Whatever's lagging goes first in the session, when you're fresh and before anything can eat the time. Adding a whole extra session is a bigger commitment that usually doesn't survive a busy fortnight; reordering an existing one costs nothing.
Check it fortnightly
Weekly is too short a window, a single missed session skews it and prompts an unnecessary correction. Two weeks smooths out normal life and is still short enough to fix a drift before it's established. Two minutes, every other Sunday.
