Shipping calculator
Delivery options
Your item’s shipping method and price are confirmed in the shipping calculator and at checkout. Here is what each delivery path means.
Items weighing 149 lb or less ship by ground parcel rather than freight.
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.
When selected and available for your address, the delivery team brings the equipment into the room, assembles and tests it, then removes the packaging.
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.
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.
Coverage and accessories have to go on the same booking as the machine. Add them here and they travel together.

I was thinking about getting Ozempic, but I’m not in the mood to go blind yet. So I decided I’d do it the old fashioned way and called CTX.

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!

Dillion was great to work with!! Super friendly, quick turn around time, and great at communicating! The guys who delivered it Robb and JJ were also amazing. 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! I would highly recommend working with them. Oh and the equipment itself is high quality and looks great in our home gym!

We purchased a Woodway treadmill from CTX Home Gyms and had a warranty issue a few months later. Dylan and his team were quick to respond, communicated throughout the process, and got everything resolved right away. Great customer service — highly recommend this company.

I can’t say enough great things about CTX Home Gyms. They did an incredible job on both my commercial gym and my home gym setup. The entire process was seamless from beginning to end — professional communication, top-quality equipment, attention to detail, and outstanding customer service.
They truly know fitness equipment and how to create a space that looks amazing and functions at a high level. Whether you’re building a home gym or a full commercial facility, I highly recommend CTX Home Gyms. They made the entire experience easy, stress-free, and exceeded every expectation.

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

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.
Assessed frame to console, then taken apart and checked part by part. Nothing gets judged from the outside.
Belts, cables, bearings, bushings, grips and safety-critical hardware are replaced as standard, whether or not they still have life in them.
Electronics bench-tested, frames and welds checked, panels refinished, then reassembled to the manufacturer's specification.
A full operational cycle under load before it ships. Anything that fails the final check goes back through service, not onto a truck.
By signing up you agree to emails about new arrivals from Build A Gym. Unsubscribe any time.

A recent Precor Discovery Series Vertical Knee Up, wrapped and photographed on the pallet before it left our Texas shop.
This is a recent unit of this model, not necessarily the one you'll receive. Yours goes through the same process.
See the full remanufacturing processCommercial-grade equipment, inspected and supported by warranty.
The Precor Discovery Series Vertical Knee Up is a dual-function bodyweight station for vertical knee raises, leg raises, and dips - extra-thick contoured elbow pads, supportive back pad, integrated dip handles, secondary stability tubing, and non-skid step-up guards - 201 lb frame, 350 lb user capacity, 27"×43" footprint. The extra-thick elbow pad specification matters specifically for knee raise volume: elbow pads that are too thin concentrate the full body weight at a narrow contact area on the ulna, which becomes uncomfortable quickly during higher-rep sets and causes users to terminate the set from elbow discomfort rather than ab fatigue. Thick, contoured pads distribute contact pressure across the entire forearm from elbow to wrist, allowing users to stay in the station longer and complete the rep range that actually develops core strength. The back pad serves a stabilization function rather than a comfort one: during hanging knee raises performed without back support, the pelvis tends to rotate forward as the user compensates for balance by pressing the back against nothing - which reduces abdominal range of motion and turns the movement into a hip flexor exercise. The back pad gives the pelvis something to brace against, maintaining posterior pelvic tilt through the raise and keeping the rectus abdominis in the loaded range. Integrated dip handles convert the station to a triceps and chest movement without requiring a separate piece of equipment.
Non-skid step-up guards for safe entry and exit. Secondary frame tubing for structural rigidity under dynamic loads. 201 lb Precor Discovery commercial frame, 350 lb user capacity, 27"×43" footprint. Remanufactured.
