Definition
The organization of your workout schedule by muscle groups or movement patterns across different days. It's how you scientifically justify why today isn't the day for that body part you're trying to avoid training.
Example Usage
His training split is so complicated it requires a spreadsheet, color coding, and a degree in exercise science to understand, when 'push/pull/legs' would probably work fine.
Origin
Emerged from bodybuilding in the 1960s as training volume increased beyond single full-body sessions
Fun Fact
Research shows training frequency matters more than the specific split used, meaning arguing about optimal splits is the fitness equivalent of rearranging deck chairs on the Titanic.
