The mechanical features on the Lifespan TR4000i folding treadmill include a 3.25 HP Continuous Duty DC motor, an 800-lb central mount incline motor, 2.5" front rollers, and 2" rear rollers. The running surface is a 1" thick reversible commercial grade deck, a 2.8mm thick orthopedic belt, and deck suspension with 8 variable density elastomers.
Along with 21 workouts, the TR4000i folding treadmill has Lifespan’s Intelli-key feature that prompts the user on the sequence of buttons to press to continue operations. It also has the IntelliStep™ technology which counts each step that strikes the deck and gives you a Step Count on the console.
A USB stick is included to interact with the online LifeSpan Fitness Club. You must first log in using your PC and set up your personal account (it’s free), then download your profile to the USB device and plug the stick into the treadmill console. The storage device will then record time, distance, steps, calories burned, heart rate, and watts. Take the USB stick back to your PC, and upload the workout, where you can print out detailed reports plus have access to more exercise programs.
The Lifespan TR4000i folding treadmill has won numerous awards in treadmill reviews from Treadmill Doctor, Health Magazine, and Runner’s magazine. It is touted for its solid and secure frame, and the space saving, fold-up design. Consumers who bought the TR4000i are more critical. They say the user interface on the website leaves a lot to be desired and needs to be updated to be fully user-friendly and functional. It isn’t necessary to use it if you just plan to get on the treadmill and run, however, the console seems to require the USB device in order to set up time/date, and user age/weight to get these readouts on the screen.
What We Say
Despite the awards, the TR4000i isn’t our favorite Lifespan treadmill. It looks like they took the TR3000 HRC and added the USB interface, beefed up the motor, and uglied up the console for this new 2010 folding model. The dark grey console is depressing and not enjoyable to look at, as well as being unnecessarily complicated. And that’s rare, because most people can easily figure out a treadmill console. Not so with this one. The website needs to be updated and until that is done, there’s no point in using that feature as a selling point. The TR4000i has all the tools — a big motor and deck, and runner’s programs, but there are too many naggly little items to ignore. For $1999, the Lifespan TR4000i folding treadmill is a very solid, powerful, and quiet machine, we just wish it were as user-friendly and attractive as the less expensive Lifespan treadmills.
