Next busy week, don't skip training entirely. Do one hard, full-body session. That single session holds nearly all the strength and muscle you've already built.
Building fitness is like charging a dead phone to full — it takes real time and effort. Keeping it charged is a quick top-up. Your body defends what it already built, so a small regular dose of training holds it, while only a long full stop drains it back down.

The Verdict
The work it takes to keep your fitness is a fraction of what it took to build it.

Moderate-High overall, and it depends which question you're asking.
A 6-month trial in already-trained adults (not untrained or older-adult samples) showing that one session a week fails to hold strength would drop maintenance from HIGH to MODERATE. The current evidence leans on shorter, less-trained samples.
If a controlled study extended sleep above a 7-hour baseline and showed real fitness gains, the "floor not a target" framing would need revising toward a true more-is-better dose-response.
