After developing a stable baseline, Alex elaborates on how to bounce the boundaries and increase the energy envelope. He uses the metaphor of being on the offensive (pushing the boundaries with activity/new foods/new supplements/new tools) versus being on the defensive (retreat, recovery, resting, stabilising). This is for a very particular stage of recovery (later stage 2/stage 3) when you are able to remain in a regular baseline without crashing, and having productive rest in order to then play with pacing.
