Proform 505CST Treadmill
Great reasons to buy from us:


iFit® Bluetooth® Enabled, 30-Day Membership Included*
- No need to find time to go to the gym anymore! With a 30-day membership to iFit®, you'll have full access to our ever-growing library of workouts. Simply connect your phone or tablet via Bluetooth® and follow our elite trainers as they lead you through workouts on and off your machine and in stunning destinations around the world. The trainers also control your incline and speed, so all you have to do is hit "Start" and get moving. Treadmill connects to tablet via Bluetooth® and does not contain a Bluetooth audio speaker. Internet and WIFI required. iFit membership activation requires credit/debit card and auto-renews for fee unless canceled 24 hours in advance.
5" High-Contrast Display
- As you power through your iFit workout, you can easily keep an eye on your workout stats, including your mileage, speed, estimated calorie burn, estimated heart rate, and time add up, with the 5-inch backlit display.
Self-Cooling Mach Z™ Motor
- Whether you want to run, jog, or walk, this self-cooling Mach Z™ motor can handle it all. Its high levels of inertia create a smooth workout experience while still maintaining low levels of volume.
18" x 55" Tread Belt
- With a 55-inch deck, you’ll have room to walk, jog, and run without feeling confined and the 18-inch width gives you plenty of elbow room as you work out. To ensure our treadmills are top quality, we test each belt for one million cycles at double the user weight before release.
QuickSpeed® Buttons for Speed and Incline Adjustments
- Adjust the speed and incline of your workout in an instant. Located right on the console, QuickSpeed® buttons make it easy to adjust your intensity. At the touch of a button, you can quickly switch between climbing hills and cooling down at the end of your workout.
0 – 10 MPH Speed
- With its powerful motor, this machine can take you all the way from 0 to 10 miles per hour. The built-in efficiency booster lets you run every day without using excessive amounts of electricity.
0 – 10% Incline
- The 505 CST lets you move between 0 and 10 percent incline so you can use incline training to increase your stamina and condition your legs.
Rebound™ Cushioning
- Every treadmill we release is equipped with cushioning throughout the deck area. So as you walk, jog, or run, you'll have a softer landing with every step. This means you can get in longer workouts with faster recovery times.
1.6" Balanced Rollers
- We know that a quality product is all about the details, which is why we've built this treadmill with 1.6-inch precision-machined, balanced, non-flex rollers. These medium-sized rollers decrease tension, which keeps wear and tear to a minimum so your machine will last for miles to come.
SpaceSaver® Design with EasyLift™ Assist
- We know you like your house to be clutter-free. So we invented a treadmill that folds up and out of the way when you're done with your workout. It totally rocked the fitness industry; but honestly, we’re just glad you don't have to sacrifice your living space for your fitness habit anymore. And as an added bonus, we built in a powerful shock that helps you lift the deck with an easy push.
Audio Auxiliary Port with Dual 2" Speakers
- Experts have learned that we increase or decrease our pace to match the tempo of our tunes, which is why we put two speakers in the console. Plus, music has also been proven to lower perceived exertion. Simply plug in your device using the audio auxiliary port and turn up the music during your workout.
CoolAire™ Workout Fan
- Our built-in CoolAire™ fan keeps your workout comfortable from the moment you step onto the deck to the moment you step off. Choose from two-speed settings for instant control - because one of the joys of indoor workouts is climate control. Even if it's raining, foggy, blazing hot, or bad air quality outside - you'll be comfortable inside.
Integrated Device Shelf
- Make fitness time multi-tasking time. This device shelf keeps your device secure and conveniently close so you have access to all your training tools and entertainment must-haves.
BILT Intelligent Instructions
- Download the free BILT app for step-by-step 3D instructions to guide your assembly
300 Lb. Weight Capacity
- Built with most users in mind, the 505 CST treadmill accommodates up to 300 pounds.
Warranty
- We want to help you protect your investment. That's why we try to go above and beyond with our product warranties. The 505 CST is protected with a 10-year frame warranty and a 1-year parts and labor warranty.
