The LifeSpan TR4000i is for individuals looking for a treadmill that has several programs for every family member and has a commercial grade deck for long-wear and good performance. It's powerful with a 3.25 HP motor and although it has a spacious 20 x 60 inch running surface the folding feature makes it easy to store when you need it out of the way.
It's easy to setup the user-defined programs, which is a good thing because this is not true of all electronic treadmills. The heart rate monitor works well and is accurate. A nice feature is the ability to record and track workouts and then upload them to their system by way of the USB drive so you can keep track of your progress towards goals.
There is no bounce to the deck during exercise so the deck is pretty stable. The cup holders on the treadmill are wide and deep enough to actually hold water bottles or a sports bottle (even a remote for TV). The construction is solid and of obvious quality.
The buttons on the arms are easy to accidentally bump which changes the incline or speed control so placement of these buttons could be better.
The Bottom Line:
The LifeSpan TR4000i is highly recommended for those looking for a quality home fitness machine that has the power and durability serious fitness buffs are looking for and donít mind putting out the cash to achieve the kind of workouts that will get results. It offers all the popular programs including heart rate, sports training, weight loss and healthy living so every family member will be happy.
