Before choosing between a treadmill, a rack, or a rowing machine, it’s worth answering a more basic question: how much exercise do you actually need each week? Most home-gym buying decisions get easier once you know the target you’re training towards, rather than guessing at “enough”. This article sets out the current UK physical activity guidelines for adults, what they mean in practice, and how they translate into equipment and session choices for a home setup.
The headline UK guideline
The NHS guidelines for adults aged 19 to 64 recommend two things every week, not just one:
- At least 150 minutes of moderate-intensity aerobic activity (such as brisk walking, cycling or rowing at a pace where you can still talk but not sing), or 75 minutes of vigorous-intensity activity (such as running or a fast spin session), or an equivalent mix of the two.
- Muscle-strengthening activity that works all the major muscle groups — legs, hips, back, abdomen, chest, shoulders and arms — on at least two days a week.
Both parts matter. The aerobic target is the one most people already know about; the strength target is the one most home-gym buyers under-plan for, even though it’s equally part of the official guidance (NHS, Physical activity guidelines for adults aged 19 to 64, reviewed 22 May 2024).
The NHS guidance also notes that spreading activity across four to five days a week, rather than trying to do it all in one or two long sessions, tends to be easier to sustain and reduces the injury risk that comes with doing too much, too infrequently.
What “moderate” and “vigorous” actually mean
These terms are defined by effect on breathing and heart rate, not by a specific machine or activity:
- Moderate intensity: your heart rate rises, you’re breathing faster, but you can still hold a conversation. Brisk treadmill walking, an easy cycling pace, or steady-state rowing at a relaxed stroke rate all count.
- Vigorous intensity: your heart rate rises further, and you can only speak in short bursts. Running, interval work on a bike, or rowing at a higher stroke rate and resistance fall into this category.
This is why the 150 vs 75-minute figures aren’t interchangeable minute-for-minute at a personal level — vigorous activity is harder to sustain, which is exactly why the guideline allows half the time for roughly the same benefit.
Translating the aerobic target into equipment choices
150 minutes a week of moderate activity is around 30 minutes, five days a week, or three longer 50-minute sessions — there’s no single correct split, and the guidance is explicit that any combination that adds up works. What tends to matter more for actually hitting the target consistently is picking equipment that fits your space, noise tolerance and schedule, since the best cardio machine on paper is the one you’ll actually use through a wet January.
If you’re deciding between the main cardio categories, our comparison of treadmills, exercise bikes and rowing machines breaks each down by footprint, noise and joint impact — all of which affect whether a machine gets used for 150 minutes a week or gets used twice and then hung with washing.
Translating the strength target into equipment choices
“All the major muscle groups, on at least two days a week” doesn’t require a full commercial rig. In practice it means each session should include movements that load your legs, your back, your chest and shoulders, and your core — not just whichever exercise happens to be easiest with the kit you own. A pair of adjustable dumbbells or kettlebells, used across squats, rows, presses and hinge movements, can meet this target on their own; a bench and a rack add range once you’re consistent, rather than being required from day one.
For anyone building this out from nothing, our guide to free weights and dumbbells and our separate guide on kettlebells both cover equipment that can cover full-body strength work in a small footprint.
What the guideline doesn’t say
It’s worth being clear about what the NHS guidance does not claim, because home-gym marketing sometimes implies more than the evidence supports:
- It doesn’t specify a particular number of sets, reps or exercises — that level of detail comes from sports-science bodies like the American College of Sports Medicine (ACSM), not the NHS’s general public health guidance.
- It isn’t a target for weight loss or aesthetic change specifically — it’s a general population health guideline aimed at reducing the risk of conditions like heart disease, type 2 diabetes and some cancers, and supporting mental health and healthy ageing.
- It applies to generally healthy adults aged 19 to 64. The NHS publishes separate guidance for older adults, for disabled adults, and for people managing a long-term health condition, and anyone in those groups — or returning to exercise after illness, injury or pregnancy — should check the guidance that applies to them, or speak to a GP, before starting a new routine.
A realistic weekly structure
A pattern that satisfies both parts of the guideline without requiring daily gym sessions:
- Three strength sessions a week (roughly 30–45 minutes), covering legs, back, chest, shoulders and core across the week — comfortably clears the “at least two days” minimum with a buffer.
- Two to three cardio sessions totalling 150 minutes at a moderate pace, or fewer, shorter sessions at a higher intensity if that suits your schedule better.
- At least one full rest day, which isn’t part of the official minutes-based guideline but is standard advice across sports science for recovery and injury prevention.
The specific split matters less than consistency across weeks. A modest routine done most weeks of the year outperforms an ambitious routine that gets abandoned in week three — which is also the more useful lens for deciding what equipment to buy, since kit that matches a routine you’ll actually keep to is a better investment than kit that matches an idealised one.
