Expert review

The at-home fitness market is booming and there are countless pieces of equipment and online fitness memberships you can buy to keep in shape. If you feel overwhelmed with so much choice, it’s worth considering investing in something that will never go out of fashion; a treadmill.

The NordicTrack S25i gives you the best of both worlds. It’s a treadmill, priced at a reasonable £1,099, that also gives you 12 months’ free access to unlimited workouts through NordicTrack’s iFit online membership platform.

The treadmill itself is really good value, with a digital incline of up to 12%, cushioning on the belt for low impact and speeds of up to 22km/h. It also has a pulse monitor, built-in fan and folds away to save space.

If you’re looking for a treadmill with a touchscreen, in-built apps and other bells and whistles, this isn’t the machine for you. But, if you’re looking for a solid, reliable treadmill that’s easy to operate and doesn’t dominate your living space, this could be just the ticket.
