LifeSpan’s mid-range TR4000i is built with serious usage in mind. Made from a rock-solid steel frame with a durable deck and powerful motor, it’s a treadmill on a mission to run forever. It’s the perfect blend of comfort, functionality and flexible workout programming that will leave you wanting to run mile after mile.

The TR4000i has eight compression shock absorbers, providing that little bit of extra ‘give’ each time your foot hits the running surface, which is a generous 20-inch x 60-inch size. That cushioned deck will guarantee comfort by reducing stress on your joints, back and knees.

It’s quiet, despite being powered by a 3.5 HP motor that provides effortless momentum to drive your legs up to 12 mph and should you be so “inclined” you can raise the treadmill up to 15%! The unit utilizes the EZfold technology, a hydraulic-assisted mechanic to fold and unfold the deck easily. It lowers itself safely under its own weight.

Nice touches include the integrated cooling fan, step counter and a safety feature that pauses the belt automatically 20 seconds after you step off it. The console has all the features you’d expect, including 21 programs, broken up with two heart rate programs, two customer customized options and 17 pre-sets. The pre-set programs include five weight management, five healthy living and seven for training, designed by sports physiologists. Use a USB stick to save your workout data and upload it to the LifeSpan Fitness Club, a great piece of tracking software that comes free with the treadmill.
