The five-to-eight-week travel window is the trap zone.
Under four weeks: detraining is minimal. P02 maintains comfortably. Over eight weeks: most people accept reality and either commit to home equipment or accept the loss. Five to eight weeks is the awkward middle. Just long enough that "I'll wait until I'm home" produces measurable strength loss and lean mass drop. Just short enough that "I should set up serious training" feels disproportionate to the disruption.
