LifeSpan TR4000i Review
Leading an impressive line of foldable home treadmills, the LifeSpan TR4000i Folding Treadmill is high quality, feature packed, and surprisingly affordable. LifeSpan treadmills in general (foldable or non-foldable) are respected for their durable components, impressive biomechanics, and generous programming options. The steel-framed LifeSpan TR4000i Treadmill outperforms its series’ other folding treadmills thanks to an extra-thick 60″ track and 3.25 HP motor.
This model also has a reversible deck to provide twice the longevity of other LifeSpan folding treadmills. The 1″ thick Phenolic deck helps to reduce workout noise, and the machine includes transport wheels, two front- and two rear-mounted, for easy movement. In addition to a cooling fan, the LifeSpan TR4000i offers dual Bluetooth speakers, as well as an Intelli-Step, a feature which works like a pedometer measuring steps taken.
For training support, the LifeSpan TR4000i features more than 50 preset workouts, including two heart rate control workouts, plus it can be used in manual mode. The unit also features three different dashboard views on its 7″ color LCD screen: The graph view, gauge view, and track view. The console is equipped with five smart buttons for easy incline, and five for speed, control. It’s smartphone compatible, syncs with fitness apps, has a tablet computer holder, and can charge mobile devices. Sale priced at just $2,399, it’s easily a best folding treadmill in its price class (and with its five-year standard parts warranty plus two years of labor, it’s a good deal at the full price of $2,597 too).
