Delivery options
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.
Size: 81" × 32" × 65" tall
Doorways: 32" at its narrowest, which is tight through a standard 32" door, worth measuring your access
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/ Build-a-Gym absolutely CRUSHED IT! I had been struggling with numerous manufacturers trying to get a seated leg press/extension that’d ship to Alaska. When I found CTX, they went above and beyond to get my Fractal packaged and shipped with no hassle. I HIGHLY recommend these folks to anyone looking for solid commercial quality equipment for their home.

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!

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!

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.
-
Moving parts rebuilt or replaced
Every moving and touched component, from belts and cables to bearings, bushings and grips, is evaluated and rebuilt or replaced, then the machine gets a full cosmetic restoration.
-
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.
Get an email when new machines land
Good units go fast. We'll email you when new machines land - nothing else.

Commercial-grade equipment, inspected and supported by warranty.
The Octane Fitness XT-3700 Elliptical Cross Trainer delivers optimized biomechanical stride path for natural forward and reverse elliptical motion, MultiGrip handlebars for upper body muscle variety, whisper-quiet operation, multiple resistance levels and preset programs, and commercial-grade construction - 350 lb frame, 81"×32" footprint. The XT-3700 is Octane's upright commercial elliptical - distinct from the xRide XR6000 recumbent elliptical in the Octane line, where the user stands and strides rather than training from a seated position. The XT-3700's advanced stride path is Octane's biomechanical engineering of the foot's travel arc: the path the foot follows through the elliptical cycle determines the joint angles at the knee, hip, and ankle, and therefore which muscles are loaded and how the ground-reaction force is distributed through the lower extremity. A stride path optimized for biomechanical precision keeps the knee tracking over the foot through the full arc, reduces lateral deviation that produces IT band and patellofemoral stress, and positions the hip at the joint angles that produce the most efficient glute and hamstring loading per stride. The reverse elliptical stride is the training feature that shifts the muscle loading pattern - forward stride emphasizes the glutes and hamstrings through the push phase; reverse stride shifts the primary loading to the quadriceps and hip flexors as they drive the rearward push. For users targeting quad development or maintaining quad strength alongside a predominantly hip-dominant forward program, reverse stride adds the quad loading variable without a separate machine. MultiGrip handlebars carry from the Octane xRide to the XT-3700 - varied grip positions change the chest, back, and shoulder loading through the arm drive, allowing users to vary upper body emphasis within a single session.
Whisper-quiet operation for home and commercial facility use. User-friendly interface with preset programs and resistance-based endurance options. 350 lb Octane XT-3700 commercial frame, 81"×32" footprint. Contact us for resistance level and program specifications. Remanufactured.

Key features
Optimized Stride Path · Forward & Reverse - Biomechanical Precision, Dual Load Patterns
Advanced stride path keeps the knee tracking over the foot through the full arc, reduces lateral deviation that produces IT band and patellofemoral stress, and positions the hip at angles for efficient glute and hamstring loading per stride. Reverse stride shifts primary loading from glutes and hamstrings (forward) to quadriceps and hip flexors (reverse) - adding the quad loading variable without a separate machine for users whose program is predominantly hip-dominant.
MultiGrip Handlebars · Quiet Operation · 350 lb Commercial Frame
MultiGrip handlebars provide neutral, wide, and narrow grip positions to vary chest, back, and shoulder loading through the arm drive - upper body muscle variety within a single session. Whisper-quiet operation for home and shared commercial environments where noise is a consideration. 350 lb commercial-grade frame for sustained high-rotation durability. Contact us for resistance levels and program details.
