Full Review

All of our top choices under $1000, including the ProForm 600i, have all of the basics:

  • Tethered safety key
  • Wheels for easy movement
  • Folds easily in half for space saving
  • LCD display


The ProForm 600i goes up to 11 mph, and go up by .1 mph increments, which is more than enough for most users. Most people jog at 5-6 mph, so this gives you the option of adding variability to your workouts.


The 600i includes  workout programs. It's also iFit enabled, which can be used on your tablet or smart phone and vary the speed and incline, and have some really cool options to make working out more interesting:

  • You can follow video workouts
  • Connect with google maps street view to change the scenery to many different places in the world as you exercise, and the terrain will change as you walk or run
  • Track all of your stats

We're a big fan of iFit, and at the current price of $10/month, or $39/month for a family, we think it's a great investment.


If you suffer from joint pain with running or walking, this could be the most important feature for you. The shock absorbers in the deck will reduce the impact on your knees, hips, and other joints significantly.

Tablet and Phone Space

There's a tablet holder on the top of the display, and there's space to hold your phone on the display.


It's not the most advanced console, but it gives you the basic information. There's a circular lighted track that tells you whether you're in endurance, tempo, or peak zone, so you can reach your fitness goals. The photo below shows a tablet above the console, it's not part of the console.


2.75 CHP (continuous horsepower) motor, which can handle longer periods of jogging or running. Motors rated by CHP are higher quality than those rated HP, as CHP rate the motor's ability to perform continuously at that rate, as opposed to at it's peak. A motor rated HP may burn out if you run it at high speeds continuously.


Treadmills in the $500-$1000 price range take longer to assemble than the treadmills under $500. It's not difficult to assemble, but it will take 2 people a couple hours on average. We recommend using 2 people as the unit is comes shipped at 224 lbs.

Weight Capacity

The 600i can accommodate users up to 325 lbs.


59.25" L x 36.63" W x 79.62" H


You can change the incline up to 12% with the press of a button, which is a great way to increase your workout without having to increase your speed.


The belt is 60" long by 20" wide, which is a great length for treadmills under $1000 and a solid width.

LCD Display

The display tracks the basics: calories burned, distance in miles or kilometers, and heart rate. It also has a unique feature in that it tells you when to lubricate the machine.


The steel frame has a lifetime warranty, the motor 25 years, and 2 years parts and labor. Solid warranty overall.
