Proform 305 CST Treadmill Review

Proform 305 treadmill belongs to the CST series and is probably one of the cheapest models designed by Proform. Just like its high-end sister models, it also has most features, but certain limitations raise questions about its quality and performance for the price.

However, when compared with other treadmills at the same price level, it stands out and offers more benefits to help you achieve your fitness goals, whether it’s looking slim and sexy at the beach or strengthen your heart to go on hiking.

So, to help you decide should you buy this treadmill, you’d better have a detailed knowledge of this model. Or should you increase your budget a bit to get an upgraded treadmill if this doesn’t stand up to the mark to you?
Without any further ado, let’s start with features and benefits.

Proform 305 CST Treadmill Features and Benefits

Motor Power

The machine is powered by 2.5 horsepower that will probably be enough for most average weight beginners to perform light exercise only, however, not for intense workout sessions or hard training. So, for the price, the motor is a bit underpowered and could be a little powerful.

But again, for beginners and basic exercise, it’s not a bad option at all.

Speed and Incline

The belt rushes at a maximum speed of 10 mph and can be lifted up to 10%. However, it’s better not to go at maximum speed because the motor might crash. Instead, try a moderate pace with incline to burn more calories to get into shape or to improve your cardio health.

Moreover, you can quickly change the speed and incline with the push of a single button from 1 to 10 numbered keys on the console. That makes the machine easy to use for all age group members.

Noise Level

At initial speeds, the motor relatively stays quiet, but when you increase the speed, it starts making some noise, which is not surprising for a home treadmill of this quality and price.

Running Area

The running area of this machine is narrow, measuring 16 inches wide but adequately long 50 inches. For most beginner users having an average physique, it shouldn’t be a problem. They could enjoy walking and jogging on it, just like outdoors.

However, taller and giant people may feel restricted, so it’s recommended that they should buy a treadmill with a broader and longer deck.

Dimensions and Folding Design

You might want a machine that doesn’t take too much space because you have a little exercising area, or perhaps you want to put your treadmill in the basement or garage. So, the Proform 305 CST is a space saving treadmill measuring 56″ long x 29.25 wide x 65″ high.

Moreover, you can fold it in the upward direction that gives you some space when needed.

User Weight Capacity

Talking about weight limit, this treadmill can bear up to 300 pounds, which is pretty good at this level and ensures that most average weight users could use the treadmill. Moreover, the weight limit itself is an indication of the quality of the treadmill.

Workout Programs

The console comes preloaded with 16 workout programs divided into four categories speed, incline, calories burned, and interval. On top of that, these programs are designed by certified trainers that ensure that you don’t do your exercise wrong.

This is pretty helpful in achieving a specific goal from weight loss to race competition to interval training. Moreover, it comes handy if you’re just starting working out.

iFit Compatible

If onboard programs don’t satisfy you, you can have enormous options of training programs through iFit. Where you select a workout for a specific outcome and can even exercise with experts and much more like competing with other online members and training at different locations via Google maps. However, it all requires you to create an account (charges apply)

Display Screen

The console features a 5 inch display screen with light, which does a great job of showing your stats in real time right in front of you. It’s one of the clearest and easy to read screens out there.

So, when you are working out, you can find out at which speed you’re running and how much distance you’ve covered in a time. Above all, the screen also displays how much calories you burnt during the session. So, setting goals and achieving them becomes more manageable.

Heart Rate Monitoring

Proform 305 CST has built in EKG grip pulse heart rate sensors. So, your heart rate will be measured by your pulse rate when you hold the sensors for a few seconds and will be displayed on the screen.

Tracking your heart rate helps you to adjust your speed and incline setting while staying in your heart zone. However, the treadmill doesn’t support any wireless method to do so.

Proshox Cushioning

The proshox cushioned deck absorbs the absorptions when you land on the deck. It decreases the chances of having soreness after a workout.
Moreover, the cushioning is adjustable that enables you to choose whether you want softer landings or more realistic feel like outdoors. It helps you do longer workouts or train yourself for outdoor landings, respectively.

Audio Compatibility

Proform 305 CST’s console also provides the convenience of listening to your favorite beats and audio through speakers using the audio port, which can help you stay motivated and perform better.


If you don’t want to stare at the boring display screen of the treadmill, you can bring your smartphone or tablet with you on the treadmill and place it right in front. Because proform 305 CST has a decently placed shelf for this that brings the internet world to your workout sessions.


Proform 305 CST comes almost assembled out of the box. You’ll just need to tighten a few nuts and bolt that shouldn’t take more than 30 minutes if you do things right, taking help from the manual. However, from unboxing to assembling it completely, can take up to 1 hour if done correctly.


The warranty on frame and motor is 5 years, which is common at this price level. It gives some peace of mind to use it for coming years.
