Expert review

The Life Fitness F3 Treadmill is quite special. It’s foldable for one thing, with FlexDeck shock absorption setting it apart from other similar models. As with any well-built treadmill you can expect a sturdy base, but the choice of two consoles: “Go” and “Track Connect” are what really make us sing here.

The Go console is the most basic of the two, but it has everything the average runner needs. 13 programs are included: three classic, two advanced, three goal-oriented and five HeartSync options. The Track console expands upon the Go’s core, connecting to Android and Apple devices through workout apps for training analysis – pretty nifty, huh? You can also access personalised workouts and real-time tracking via the Life Fitness Track console.

So what are the downsides? If we’re being picky, the model’s track is a little short – it’s a typical size for a walker’s treadmill, but not really long enough for taller runners. We’re also going to be critical of its overall size – you’ll need a good deal of space for this treadmill when it isn’t folded up and even when it is folded, the dimensions are on the larger side.

Overall, the treadmill boasts many more benefits than drawbacks but with a rather hefty price tag, it’s a model we’re going to recommend for the more serious of you athletes out there.
