All working weights are computed off these. Every 4-week cycle they adjust themselves off the reps you log on the "+" sets — big rep-outs earn bigger jumps, grinders hold steady, nSuns-style. You never touch these unless something feels way off. First week of a cycle should feel easy — that's the program working.

Rough day?
Log whatever you did instead — bike with the kids, yard work, anything. It keeps the streak. The week is the target, not the day.
