Treadmills for heavier users

Written by Jamie Miller, Founder & Editor · Last checked 18 September 2026

Yes — there is a real, sourced machine rated well above 25 stone (158 kg). The NordicTrack Commercial 1750 is rated to 182 kg, about 28.7 stone, with a full manufacturer specification behind it. That said, it is the exception rather than the norm: most established brands with published specifications stop between 100 and 136 kg, and only three of the machines we have sourced clear 150 kg at all.

Search Amazon and you will also find listings claiming 150 to 180 kg from sellers with no manufacturer site behind them — see below for why those are not on this page. The point is not that heavier users have no real options. It is that the options narrow fast, and a search engine result page full of budget machines rated to 100 kg makes it look narrower still than it actually is.

What is above 182 kg, and why it is not on this page

Search Amazon and you will find treadmills advertising 150 kg, 160 kg, and at least one claiming 180 kg or more — figures that, before the NordicTrack above was sourced, we could not distinguish from genuine machines using volume alone. We still have not recorded a single one of those marketplace listings, because the specifications on them are written by the seller and there is no manufacturer site behind them to check against. There is no specification sheet, no manual, and often no brand that exists anywhere except on that listing. Compare that with the NordicTrack: a named manufacturer, an established UK retailer, and a full specification table.

A weight rating is a structural claim about a frame, a deck and a motor. An unverifiable one is worth less than no claim at all, because it invites you to trust a machine with your safety on the strength of a number somebody typed into a product title. We are not going to launder those figures into this page by repeating them. If a manufacturer publishes a specification we can read, its machine will appear here.

Maximum user weight is a structural limit, not a guideline

It is not a polite suggestion about comfort. It is set by the frame, the deck and the motor together, and each of the three is doing something different. The frame carries static load. The deck absorbs impact, which at running speeds is several times body weight on each footfall. The motor has to move the belt against that load continuously rather than in bursts.

Exceeding it wears all three faster than the warranty assumes, and most manufacturers exclude damage caused by exceeding it. Treating the number as a hard line is the correct reading.

What the machines with checkable specifications publish

Each figure is the number its own source publishes, read on the date shown and marked with where it came from. 4 of them are retailer listings rather than manufacturer specification pages, which is weaker evidence and is graded as such. We have not weighed or tested anything.How we review.

The trade nobody warns you about

The two strongest machines in that table are also the two that do not fold. That is not a coincidence: the frame and deck that carry more load are heavier and more rigid, and rigidity is the opposite of a folding hinge. As you go up the weight ratings you lose storability, and the machine itself gets heavier, which matters if it has to be moved or carried upstairs.

So the real question is not "which machine is rated highest" but "which machine is rated adequately and still fits my life".

Four things that matter more than the headline number

1. Deck width, not just length. Length decides whether you can run. Width decides whether you feel secure, and it matters more at a heavier weight and at walking speeds, when your gait is wider and you are more likely to be watching something rather than your feet.
2. Continuous motor rating, not peak. A heavier user loads the motor continuously, which is exactly the condition peak horsepower does not describe. Where a brand publishes only a peak figure, or does not say which it is quoting, you are being told less than it appears. Our records mark which is which, and several manufacturers do not say.
3. What the warranty actually covers. Most UK manufacturers publish one combined term rather than separating motor from parts, so "5 year warranty" may not mean what you assume about the most expensive component. Read the exclusions for exceeding the weight rating.
4. Cushioning, described honestly. Manufacturers count mounting points. A count is not a measurement and nobody publishes impact figures, so treat "8-point cushioning" as a description of construction rather than evidence of how it feels.ENot established, checked 18 Sept 2026

If you are above the published ratings

Be straight with yourself about it rather than buying at the limit and hoping. Three honest routes:

• Walk first, on something rated for it. Walking loads a deck far less than running does, and a machine comfortably within its rating will last where one at its limit will not. Incline walking raises effort a lot without raising impact.
• Look at light-commercial machines. They are built for continuous multi-user duty, are rated higher, and are heavier and more expensive. For someone who would otherwise exceed a home machine's rating, the maths can work.
• Consider that a gym machine may genuinely suit you better for now. Commercial treadmills are rated well above home ones, and no amount of wanting a home machine changes what a frame will carry.

What we have not established

We have not tested any of these machines, we have not verified a single manufacturer's weight rating independently, and we have no failure-rate data for machines used at or near their limit. The ratings above are what manufacturers publish, graded accordingly. If you own one of these and have used it near its rating, tell us what happened — that is the evidence this page is missing.
