How delivery works
Your item’s shipping method and price are confirmed in the shipping calculator and at checkout. Here is what each delivery path means.
Driveway freight delivery
Your equipment is palletized and protected. The freight carrier schedules delivery, then uses a liftgate to lower it to your curb or driveway. Moving it inside and unpacking it are up to you.
Inside delivery & assembly
When selected and available for your address, the delivery team brings the equipment into the room, assembles and tests it, then removes the packaging.
Full truckload
For commercial builds and multi-pallet orders, a dedicated trailer keeps the full order together in one delivery. We confirm the unloading plan before the truck ships.
Power: Standard household outlet, no dedicated 20A circuit needed, adapter included
Size: 83" × 37" × 62" tall
Doorways: 37" at its narrowest, wider than a standard 32" door. It arrives assembled, so measure your access and tell us if it is tight
What Remanufactured Means
Every remanufactured machine is fully disassembled, deep cleaned, repaired or re-parted to factory spec, then tested under load before it ships. Backed by one year parts and labor, with extended coverage available.
Warranty Coverage
New and remanufactured equipment are both covered for one year, parts and labor, backed by us. Extended protection is available on either through BAG Care+. Used equipment is sold as-is with no warranty coverage, and is described honestly before you buy. We service nationwide - every ZIP code in the country - so coverage travels with the machine.
30-Day Returns & Exchanges
Change your mind within 30 days of delivery and you can return the machine or exchange it for a different size, color or configuration.
Return shipping is the customer's responsibility and a 15% restocking fee applies to preference returns and exchanges. Freight items must go back packaged to the same standard they arrived in. We will tell you exactly what that means before anything is collected.
Anything that arrives damaged or fails under warranty is handled separately and carries no restocking fee. Full terms are in our Returns, Exchange & Refund Policy.

CTX stands by their products. I recently purchased a Precor elliptical from them & it arrived with a mechanical flaw. They coordinated with a technician to get my product fixed like new. They accomplished this despite the fact that my home was two states away. Special thank you to Nichole for staying accessible and attentive throughout the process!

Absolutely best in business! Not only is Dillon just genuinely a great human being, he’s real and honest. Loved everything I’ve gotten from him and the team. I’m about 10-15 pieces in deep with him and not stopping anytime soon! Absolutely recommend hitting these guys up for home/commercial equipment. New or refurbished!

They came prepared and were very fast and efficient. They offered to help us move around other equipment to ensure we loved our gym! Super nice people and an amazing company!

Dillon and his team outfitted my entire new gym. We worked together from the beginning stages. They had the same exact vision I had. They did everything possible to make our dream gym. And they did!!

The entire experience was amazing. I literally told them what I wanted and they made it even better. The Build line is amazing. I get compliments on it daily. From the stitching on the equipment to how smooth it is. I can not say enough good things about it. And the plate loaded build equipment is legit. I’m an equipment snob. I love finding the old pieces. But this stuff is even better. Pure quality and can stand some big weights!
We plan on opening a couple more gyms, and we are definitely usi -

Rebuilt in our Jarrell, TX shop
What remanufactured means here
Every machine we sell as remanufactured goes through the same process, whatever the brand or the price. Not a wipe-down and a price tag.
-
Inspected and stripped down
Assessed frame to console, then taken apart and checked part by part. Nothing gets judged from the outside.
-
Wear parts replaced
Belts, cables, bearings, bushings, grips and safety-critical hardware are replaced as standard, whether or not they still have life in them.
-
Refinished and rebuilt to spec
Electronics bench-tested, frames and welds checked, panels refinished, then reassembled to the manufacturer's specification.
-
Tested under load
A full operational cycle under load before it ships. Anything that fails the final check goes back through service, not onto a truck.

Commercial-grade equipment, inspected and supported by warranty.
The Life Fitness CLST Integrity Series Treadmill is a commercial-grade running platform with a 20" × 60" running surface, 3.5" precision crowned steel rollers front and back, and a 0.5 to 14 mph speed range - the 14 mph top speed and large deck accommodate serious sprint training and high-output running beyond what most consumer-grade treadmills support. A 15% maximum incline adds hill simulation capability across the full speed range.
The console offers an exceptionally broad program library - over 20 programs including military fitness test protocols (Army PFT, Navy PRT, Air Force PRT, Marine PFT), sport training programs, heart rate interval modes, and 6 custom workout slots. Readouts include watts, METs, distance climbed, and calories burned alongside standard time, speed, and incline metrics. Headphone jack, integrated reading rack included. 425 lb commercial frame. Remanufactured.
