#1 ProForm Fit 425 Treadmill Review

The ProForm Fit 425 Treadmill is best for people who want an affordable exercise machine that isn't too complicated. It performs best when you're walking or lightly jogging, and it even comes with an EKG heart rate monitor if you need to stay within a given range.

Is the ProForm Fit 425 Treadmill best for you?

The ProForm Fit 425 Treadmill isn't the latest and greatest model out there. Still, if money's tight, then it works in a pinch. It still manages to come with shock-absorbing cushioning to prevent your knees from taking on too much stress. You can jog without worrying about needing several days of recovery time afterward.

You need to sign up for an iFit membership to use this treadmill, but it may be precisely what you need to get in more efficient workouts. You can engage in trainer-led exercises or take advantage of Google Maps to look as though you're jogging around the globe.

Consider ProForm Fit 425 Treadmill if...

  • You need affordability. What it lacks in the latest features, it makes up for in price. It's one of the few treadmills you can buy for under $500.
  • You plan on using iFit. iFit has changed what you're capable of achieving with at-home workouts. Luckily, this treadmill, despite the low price, still works with the app.
  • You like heart rate monitoring. This treadmill comes with an EKG heart rate monitor. You simply grip the handle, and you can easily stay within a targeted range.

Avoid ProForm Fit 425 Treadmill if...

  • You need a longer warranty. You don't get a ton of protections with this device. The motor is only covered for 3 years while parts and labor are even fewer.
  • You want foldability. Some models, like the ProForm 705 CST, are able to fold in. This allows you to create more room in the space it's in when you need it. However, this model doesn't come with such capabilities.
  • You want minimal maintenance. Some reviews note how you have to tighten the belt every so often. It tends to come undone at higher speeds.
