$1,000 to $2,000
This mid-range price category includes many recommended folding and non-folding models. If space isn’t a concern, definitely check out the Sole S77. It’s one of our highest-rated non-folding treadmills, whether you’re walking, jogging, or doing intense interval training. You might even do better than $1,900 we paid, since Sole has since introduced a newer version of this machine.
If you need a folding treadmill in this price range, we really liked the ProForm Pro 2000, $1,250. This well-built, versatile machine is also iFit compatible, meaning it can generate real-world routes on Google Maps (say if you're training for the Boston Marathon) or let you compete against friends; note, however, that the required module is sold separately.
$2,000 and up
In addition to the abovementioned Precor 9.31, there are several extremely solid and innovative options among high-end treadmills. Consider the Landice L7 Cardio Trainer, a $3,800 non-folding model with exceptional performance and some high-tech features, including iPhone connectivity. There’s also the True PS300, $3,000, with its wide range of exercise programs that are easy to follow on the console’s crisp LCD display.
Each of these price categories also contains a number of treadmills that were less impressive in our tests, so be sure to check our treadmill Ratings carefully before making your final decision. Our buying guide offers additional helpful information, including a video from our labs of how we test treadmills.
