January 26, 2021

The Life Fitness T3 Treadmill is built for people of all fitness levels. Whether you're a novice looking to begin a workout regimen or an expert that needs a machine with speed and incline, this machine offers an array of features to give you the workout you're looking for.

Is the Life Fitness T3 Treadmill best for you?

The Life Fitness T3 Treadmill is designed to support everyone. The running track offers shock absorption technology preventing your joints from being easily injured. With a quick start mode, you can hop on and get running in no time; perfect for people who want to exercise in the comfort of their homes.

You also have a bit of customization to decide upon. There are 2 consoles you can choose from. They each offer over a dozen preset programs to give you some direction, but only one comes with iPod compatibility. You may need to consider what you want out of your treadmill, and how much you're willing to spend, before making a purchase.

Consider Life Fitness T3 Treadmill if...

  • You need a steady incline. This treadmill is capable of a 15 percent grade, moving upward in 0.5-percent increments. A slight incline does wonders for burning calories, so it's a handy feature to have for those interested in losing weight.
  • You want an eco-friendly machine. It also features power-saving capabilities. It automatically draws less power when not in use, so it's not as much of a drain on your electric bills.
  • You like having different user profiles. Depending on the console you purchase with your treadmill, you can create either 2 or 4 user profiles. This allows you to monitor your progress without interfering with someone else's.

Avoid Life Fitness T3 Treadmill if...

  • You live somewhere small. Life Fitness makes treadmills that are larger than most. As a result, they may not be suitable for apartments or smaller houses.
  • You want simpler assembly. This treadmill comes with a 32-page manual (18 of which are pages devoted to assembly!) It's difficult, so you may want to consider paying someone else to put it together for you.
  • You're on a budget. The T3 may not be as expensive as the Life Fitness T5, but it still costs more than other treadmills from different brands. Expect to spend several thousand dollars on this purchase.
