There is a particular kind of Monday that I hear about more than any other. It follows a Saturday that started with good intentions — a long walk somewhere with a view, a five-a-side match, a class that a friend had been recommending for months — and it arrives with stiff legs and a slightly bruised ego. The person telling me about it is usually not unfit. They have simply spent five days sitting down and then asked their body, on a Saturday morning, to behave as though they had not.
I find this pattern genuinely interesting, because almost nobody plans for it. We plan the activity. We plan the kit, the route, the meeting point. What we do not plan is the fact that the weekend athlete and the weekday desk worker are the same person, and that the five quiet days in between are doing more to shape Saturday than Saturday itself is.
The gap is not fitness, it is preparation
When someone tells me they felt flat on a Sunday hike, my first thought is rarely about training. It is about the week that preceded it. A desk week has a very consistent shape: long stretches of sitting, a lunch eaten at speed or at a keyboard, hydration that drifts because the kettle is closer than the tap, and an evening meal that is frequently the only properly considered thing on the plate all day.
None of that is a failure. It is just a week. But it means the active weekend does not begin from a neutral starting point — it begins from five days of habits that were optimised for sitting still. The useful question is therefore not “how do I get fitter for Saturday” but “what can I keep steady from Monday to Friday so that Saturday is not a shock”.
A short weekday checklist
I keep this deliberately small, because a long list of weekday rules is exactly the sort of thing that survives until roughly Tuesday lunchtime. Four things:
- Move the sitting, not just the sitting time. Standing up every hour, taking a call on your feet, walking the long way to wherever you are going. It is unglamorous and it does more for Saturday than a heroic Thursday gym session.
- Eat a breakfast that is actually a meal. The desk week tends to erode breakfast first. It is also the meal you have the most control over, which is why I would defend it before anything else.
- Drink water on a schedule, not on thirst. Office thirst is a poor signal. A bottle on the desk that you refill twice is a better one.
- Keep your daily nutrition running on the quiet days too. Consistency across the flat weekdays is what makes the active day feel less like a jolt.
Why the weekdays are where personalised nutrition earns its place
This last point is where I usually end up suggesting Bioniq GO, and the reason has nothing to do with Saturday. It is that a desk week is easy to take a supplement in and easy to forget one in, depending entirely on how much friction the routine carries. A cupboard of separate tubs carries a lot of friction. One daily dose carries almost none.
Practically, it is a personalised daily supplement rather than a generic one. You take the free Wellness Assessment — no blood test needed — and your answers match you to one of 40 formulas, with up to 23 science-backed nutrients in a single daily dose of Swiss granules. No pills, vegan-friendly, and formulated to support goals such as everyday energy and focus, an active lifestyle and long-term wellbeing, as part of a balanced diet. Bioniq was founded in London in 2019, and its personalised nutrition business is now part of Herbalife.
The relevant detail for the desk-then-hike pattern is that the assessment asks about how you actually live — including how active you are — so a person whose weekends look like this gets a formula shaped around that, rather than around an average. I have written separately about how Bioniq decides which of its formulas fits you if you want the mechanics of that.
Saturday itself
On the day, I would resist the urge to do anything clever. Eat properly before you set off rather than relying on whatever is at the halfway point. Take your daily sachet at breakfast as usual — the routine does not need a special weekend version. Carry water and something to eat that is not a last-minute garage purchase. And be realistic about the jump: if the week was entirely sedentary, a first outing that leaves you able to walk on Sunday is a better outcome than one that does not.
Food supplements are not a substitute for a varied, balanced diet and a healthy lifestyle. Nothing in a sachet replaces the walk, the sleep or the meal — it sits alongside them.
If the active side of your weekend is growing, our Energy and Fitness range covers the shakers, hydration and protein side of it. And if you want the weekdays to stop undermining the weekends, build your personalised formula and let the quiet five days do some of the work.
