 Design and Construction

Frame and build quality

The ProShox cushioning system minimizes joint impact, ensuring a safe and comfortable workout experience. The 1.9″ precision-balanced, non-flex rollers and multi-ply belt contribute to smooth and quiet operation.

 Technological Features

Console and display

The 305 CST treadmill comes with a 5-inch high-contrast, backlit display, providing easy access to workout metrics, such as time, distance, calories burned, and heart rate. The console also includes an integrated tablet holder for additional entertainment options during workouts.

iFit compatibility

The treadmill is iFit-enabled, offering a wide range of interactive workouts, personalized training programs, and global running routes. With iFit, you can participate in on-demand, trainer-led workouts, track your progress, and even compete with friends. Note that the iFit membership is sold separately.

Incline options

The 305 CST treadmill offers an incline range of 0% to 10%, allowing for diverse workouts that target different muscle groups. The incline feature enables a more challenging workout and helps simulate outdoor running conditions.

Workout programs

The treadmill comes preloaded with 16 workout programs, focusing on calorie burning, incline training, speed goals, and interval training. These programs cater to various fitness levels and goals, ensuring a well-rounded workout experience.

 Additional Features

Heart rate monitoring:

The 305 CST treadmill monitors contact heart rate through the EKG grip pulse sensors on the handlebars. This offers quick readings, although it may not be as accurate as a Bluetooth-enabled chest strap (sold separately).

Audio options

The 305 CST treadmill comes with an integrated sound system, featuring dual 2-inch speakers and an auxiliary music port, compatible with most MP3 players and smartphones.

 Potential Drawbacks


Some users may find the assembly process time-consuming and challenging, requiring two people for optimal assembly. However, ProForm does offer an in-home assembly service for an additional fee.

iFit subscription cost

Although the iFit platform offers numerous benefits, the subscription cost may be a deterrent for some users. However, the treadmill’s preloaded workout programs provide a variety of options for those who choose not to subscribe.

Motor power

The 2.0 CHP motor may be suitable for walkers and light joggers, but more advanced runners or those with higher intensity training goals might find it lacking in power for their needs. However, the motor should suffice for entry-level users or those looking for light to moderate workouts.

Warranty and Customer Support

While there are a few potential drawbacks, such as the assembly process, smaller running surface size, and limited motor power, the 305 CST’s overall performance and benefits outweigh these concerns.

In summary, the ProForm 305 CST treadmill offers a combination of design, technology, and performance, making it a standout choice for home fitness enthusiasts on a budget. Its extensive features, competitive warranty, and reliable customer support make it a valuable addition to any home gym.
