The Method
Program Day
One day inside your Program.
A Program contains several Program Days, each one a slot in your week: Alpha and Beta in the warm-up, then lettered days in the main cycle. Train three days a week and your cycle has three (ABC); train four or more and it has four (ABCD).
The letter is the organization. What each day trains is resolved for you, from your week. "Day A · Push" is a label you read, not a rule carved in stone.
