ProForm ZT6 Review

Editor's Rating: 7.1 /10
This model is discontinued.

Often sale priced as low as $599, the ProForm ZT6 is one of ProForm’s most affordable treadmills for walkers and joggers. Like many other ProForm treadmills, it can easily fold for storage. It has a 55″ track, a 2.5 CHP motor, a maximum 10% power incline, and 18 built-in workouts. Parts and labor are under warranty for a year.

The ProForm ZT6 is almost identical to the ProForm Performance 400i. The main difference between the two models is the console. On the 400i, the console is wired for use with iFit. It also has ProForm’s Watts meter as the centerpiece of workout feedback. On the ProForm ZT6, iFit isn’t an option but the menu of preset programs is long. The workout feedback is provided with a traditional treadmill display that some users find preferable to the Watts meter on the 400i.

With its low sale price, the ProForm ZT6 could be a good starter treadmill. Just keep in mind that its track is only 55″ long and that this machine’s motor wasn’t designed for marathon training.

What We Like:

  • SpaceSaver: The treadmill deck can be tilted upward to save floor space after workouts.
  • Workout Guidance: The console provides plenty of exercise guidance with 18 preset workouts designed by certified personal trainers. These workout programs fall into four categories: Calories, Speed, Incline, and Intensity (while the Performance 400i also has 18 programs, they are categorized only as “Tempo” and “Interval Training”). The programs automatically adjust the treadmill’s incline and speed, with maxing out at 10% and 10 mph respectively.
  • Power Incline: The automated ramp is a useful feature that isn’t included on all discount treadmills. On the ZT6, a maximum 10% incline offers a metabolic boost and targeted muscle toning.
  • Cushioning: ProShox cushioning is decent for a budget treadmill. It can reduce the stress on your joints by up to 28% compared to outdoor tracks.
  • Grip Heart Rate Monitor: Heart rate sensors are built into the handlebars so that readings can be obtained during workouts. The data isn’t hospital-accurate, but is a useful guide.
  • Audio: The ZT6 Treadmill can play your favorite MP3s to help you keep pace. It has a smartphone-compatible port and Intermix Acoustics 2.0 speakers.

What We Don’t Like:

  • No Workout Fan: Odd since this is standard on other ProForm treadmills.
  • Track: The 55″ track is too short for some walkers and many runners. Unlike more expensive treadmill tracks, it isn’t designed for longevity.
  • Motor: The 2.5 CHP motor for the ZT6 Treadmill isn’t one of ProForm’s best.
  • Warranty: This warranty package is below average. It includes lifetime coverage for the frame, 25 years for the motor, and a year for parts and labor.


Our Verdict:

A low sale price makes the ProForm ZT6 Treadmill pop out as a good buy for walkers and joggers. It might be a good choice if you’re focused on the short term and aren’t interested in using iFit. Just don’t be surprised if you have to repair or replace this product within a year or two. This machine was not built to last. This treadmill might be rewarding for a while, but spending a bit more will bring you much more value. Check out our best cheap treadmills article to spend your money more wisely..
