Finding the energy — and the time — to exercise on a shift pattern that never settles is one of the hardest habits to build. It’s also one of the most protective things you can do for a body under the strain of irregular hours.
Why it matters for shift workers
Exercise offsets a lot of what shift work does to the body. Regular movement helps regulate blood sugar, protects cardiovascular health, and supports the circadian system that irregular hours keep knocking out of sync.
It’s also one of the few tools that works on your mood directly and immediately — helpful when isolation and fatigue from working unsociable hours start to weigh on you.
Fitting exercise around your shift
Timing matters more than intensity when your schedule is irregular. A brisk walk or light resistance session shortly after waking — whatever time that is — acts as a strong signal to your body clock, similar to morning light. Save the harder sessions for earlier in your ‘day’, and avoid intense exercise in the few hours before you plan to sleep, since it raises core temperature and alertness right when you need both to fall.
Consistency beats perfection. Short, regular sessions you can actually keep up around a rotating pattern will do more for you than an ambitious programme you abandon after a fortnight.
What Huberman recommends
Protocols lays out structured approaches to cardiovascular and resistance training, along with the science of why movement timing affects sleep, mood and metabolism. We’ve written companion notes on adapting these for people who don’t get a normal 9-to-5 to build a routine around.
