Why lockd
Trained on principles, not a PDF.
A generic plan doesn't know you can never train on Mondays, or that swimming is your weak spot. lockd does, and it follows the same principles a good coach would.
80/20
Mostly easy
Around eighty percent of your time is easy. Hard work is capped at 14 percent in base, 22 in build and 28 in peak.
8%
Build gradually
You start at 70 percent of your hours and add no more than 8 percent a week. After that, only the intensity changes.
65%
Recover every fourth week
Three weeks of building, one week at 65 percent. In the taper, volume halves while intensity stays.
48h
Space between hard days
Never two hard sessions in a row, not even across the weekend.
How lockd splits your hours
The baseline split. Your weakest discipline gets six extra percentage points, taken from the other two.
