VS.

Xterra Fitness TR 6.6 treadmill

We have visited many review sites but have never been quite able to find an answer to the question on which treadmill is better between the LifeSpan TR1200i and the Xterra Fitness TR 6.6 models. We do have a very conclusive answer to this question.

We decided to answer this question because both models are very closely price in the $1000 and under price range. And on top of that, in our opinion our two of the top models you can buy in this price range.

To make it less confusing we will only deal with the “meat and potatoes” and not the extras such as what type of exercise programs or does it have built-in speakers. Just over functionality as a machine. The areas we will address to make our comparison are:

  • lifespan tr 1200i vs Xterra TR 6.6 treadmil

    Lifespan TR 1200i

    Motor

  • Frame
  • Tread belt
  • Cushion System
  • Warranty

Area #1 – Motor

If you are going to spend $1000 on a treadmill you will want to make sure it has a certain type of motor, a Continuous Duty Horsepower (CHP) as these are the most durable and efficient style of motor. Both the LifeSpan and the Xterra models that we

are comparing here do have this style of motor.

However, the Xterra TR 6.6 has a larger more powerful 3.0 horsepower version of this motor, the LifeSpan TR1200i has a 2.5 horsepower.

This difference is probably most important to a person buying a a home treadmill with the intention of running. The Xterra also has a top speed of 12 MPH compare to 11 MPH of the LifeSpan model.

Winner in Motor:  Xterra Fitness TR 6.6

Area #2 – Frame

Treadmills frames are primary made out of either steel or aluminum. For a variety of different reasons, the best frames are made from steel.

Both models have frames constructed from steel.

Since both models are constructed from steel it is hard to assign a cear cut winner in this area. But what we will say, the frame construction has a lot to do with maximum user weight capacity. The Xterra has a weight capacitiy of 350 lbs while the LifeSpan has a weight capaity of 300 lbs.

Winner in Frame: Slight advantage to Xterra Fitness TR 6.6

Area #3 – Tread Belt 

The tread belt is the platform you exercise on (walking, jogging, running). Two areas of concern when judging a belt are ply (thickness) and dimensions.

The belts of both these models are the same thickness. But there is a difference in dimensions.

  • Dimensions of the LifeSpan TR1200i: 20 x 56 inches (W x L)
  • Dimensions of the Xterra Fitness TR 6.6: 20 x 60 inches (W x L)

While 56 inches in length is decent for running, if you are a taller person or a runner with long strides the extra 4-inches the Xterra provides in length would be a benefit.

Winner in Tread belt: Xterra Fitness TR 6.6

Area #4 – Cushion System

These systems are designed to transfer and dissipate energy as you exercise. It absorbs and dissipates a certain percent of the energy preventing it from returning back into your feet and up your legs to damage your ankles, knee and hips joints.

Both models are equipped with a cushion system.

We don’t feel there is a significant difference here to declare an overall winner in this area. Also, as individuals we all have slightly different mechanics in walking, jogging and running. Depending on mechanics, one person might find one model more comfortable than the other but another person might have the opposite experience in comfort.

In our opinion, the cushion systems built into these two treadmills are very close.

Winner in Cushion System: Tied

Area #5 – Warranty

When looking at treadmill models in with prices near the 1000 dollar mark if you do not see warranties offering lifetime guarantees on both the motor and frame this should make you question the quality of what you are looking at.

Both these models provide lifetime warranty on the motor and frame.

Winner in Warranty: Tied

LifeSpan TR1200i vs. Xterra Fitness TR 6.6 treadmill

As we wrote this review in 2016, the prices of these models were nearly equal.  Based on function, in our opinion the overall winner is the Xterra TR 6.6 treadmill. Both are good choices in the $1000 price range for 2016.

If you are buying a treadmill for the purpose of running we would recommend to especially take a look at the Xterra model listed here as it provides a higher horsepower motor and also a long running platform.

We compared these two models because on many review sites that list the best treadmills for under $1000 we commonly see mention of the LifeSpan TR1200i but less commonly see mention of the Xterra Fitness TR 6.6 treadmill as the best option.
