With cushioning and an on-board fan, the Proform 905 CST makes working out comfortable. There are a few concerns regarding the iFit membership option, however, you can get exercising with one of the 30 pre-set modes the 905 CST already comes with without any subscription if you choose not to pay for this feature.

Is the Proform 905 CST treadmill best for you?

The Proform 905 CST has everything you want out of a modern treadmill. It comes with an extremely soft running surface with built-in shock absorption to protect your joints and muscles. And that's just one of the many features that encourages you to work out on the treadmill as often as possible.

It's foldable, allowing you to take it out and put it away with ease. And the tablet holder is great for bringing your iPad to your workout station to watch whatever you want. Convenience is front and center with this treadmill as is power and ease of use.

Consider Proform 905 CST if...

  • You need plenty of room to grow. The Proform 905 CST lets you ramp up the speed to 12 miles per hour and the incline up to 12 degrees. Even if you don't start at that point, it leaves you with space to grow. So you can continue ramping up your workouts to perform your best.
  • You want cushioning for your legs. This treadmill comes with a ProShox cushioning system on the belt to reduce the impact on your legs. For people with leg or foot issues who may be wary of running, this treadmill is supportive of any past or present injuries.
  • You like staying cool. The Proform 905 CST treadmill boasts a CoolAire fan in its construction. You can have it blowing on your face to keep you cool as you run. It mimics the sensation of running outside with the wind blowing.

Avoid Proform 905 CST if...

  • You don't need a chest strap. This treadmill allows you to monitor your vitals with EKG grip pulse sensors and a chest strap. Most treadmills only come with the pulse sensors. For some people, a chest strap may be too cumbersome to get any use out of.
  • You don't want an iFit membership. When you first set up your treadmill, it tries to force a subscription to iFit on you. It comes with some handy features, but at $15 a month, it's understandable if you don't feel like paying more just to run.
  • You don't like struggling to hear music. The Proform 905 CST lets you hook up your smartphone or MP3 player to the treadmill itself. The machine plays your music. But some reviewers note how it's hard to hear anything when you're running. It seems to do all right when you're just walking.

Reasons to buy Proform 905 CST?

  • You want to bring your tablet with you. The tablet holder makes it easy to watch movies, read digital books, or chat with friends as you work out. The holder rests at eye level, so you can be productive in more than one way while exercising.
  • You have limited space. You may not have the room to keep your treadmill open all the time. The Proform 905 CST is foldable. So you can take it out when you want to run and then slide it under the bed when you're done.
  • You want iFit Studio Classes. It's not mandatory to sign up on the app. But if you want to bring an energetic workout atmosphere into your home, this is the way to do it. You get a personal trainer on your screen to push you through the session so that you don't lose any momentum.

Reasons to avoid Proform 905 CST?

  • You want to make custom workouts for free. The Proform 905 CST only allows you to create personalized workouts with an iFit membership. You still have 30 built-in programs to choose from. But anything else costs you extra.
  • You don't want to feel taken advantage of. The Proform 905 CST doesn't tell you how to bypass the iFit membership step if you just want to run on your treadmill. All you need to do is press the iFit Sync icon for a few seconds until it beeps twice. But it's hard to go through that and not feel like the brand tried to pull a fast one on you.

Our verdict

The Proform 905 CST is a solid treadmill once you get it up-and-running. A lot of users note how frustrating it is to bypass the seemingly forced iFit subscription, but once you get that squared away, the treadmill itself is a great workout piece for your home.
