It's a queue, not a calendar. Miss a day? Nothing breaks — you just do the next one next time. Each session has Full / Trimmed / Floor versions: cut Builders if short on time, cut the Tail on bad sleep. Anchors never get cut — they carry the muscle-retention signal.
Lifts first, swims second — never the reverse. If the lifts start feeling weak (load dropping, reps vanishing), that's the signal conditioning is outrunning recovery. Pull back the swimming, not the lifting.
