You must also check to see if the belt hasn’t loosened between workouts.

Warranty and Guarantee Information

Apart from its components, the Proform Performance 400i treadmill doesn’t require additional accessories. However, long-time users suggest purchasing a bottle of professional lubricant that will ensure the well-functioning of your treadmill. Apply it periodically to maintain a silent, comfortable use of your treadmill.

Recommended Routine

After you get your Proform 400 treadmill set up, it is highly important to maintain a safe workout and follow professional guidance. We recommend beginners use the workout apps. These apps were designed by fitness professionals. The workout apps have a relatively gentle learning curve.

Beginner runners should only attempt workout sessions that are set according to their levels. Start at a lower level and then gradually increase the intensity and duration of your workout. Maintain a healthy lifestyle and include running on the treadmill Proform 400 in your daily routine in order to get the best results.

  • Incomplete manual. – A few users have mentioned in their Proform reviews that the treadmill manual didn’t include enough information about the monitor. Specifically, it didn’t mention how to set up the workout apps. Most of them said that they had to spend some time figuring everything out by themselves.
  • Customer Service Issues. – Some users have mentioned a few issues they have encountered while trying to get in touch with the customer service department. Apparently, the staff members were not quick enough to fix the reported issues.
  • Poor Speakers – The in-built speakers of this treadmill are slightly subpar. Even though you can connect your iPod to the treadmill, you’re probably going to be stuck listening to podcasts.

User Reviews

ProForm 400 treadmills are mixed. Overall, most users are happy with this ProForm treadmill model. Many found the workout apps quite useful, and the general consesus is that the ProForm treadmill is quite sturdy, even after prolonged use.

As mentioned, the quality of the speakers is the main weakness of this treadmill. However, it’s a relatively minor complaint. Some users also complained about the monitor, which in some cases doesn’t work properly. However, when looking at other ProForm treadmill reviews for this model, it seems this depends a lot on how lucky you are. Many users claimed they had no issues with the monitor whatsoever. Unfortunately, if you are one of the unlucky customers who has problems with the monitor, you’ll have to deal with the ProForm customer service department. And that, it seems, can be a major hassle.

Our Recommendation

We highly recommend this affordable product for anyone who wants to get in shape without spending too much money. The Proform Performance 400i treadmill, in spite of the fact that it’s one of the cheaper treadmill models available, has many of the features you’d expect from a high-end treadmill.
