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 — tight through a standard 32" door, worth measuring your access
Financing: From $174.37/mo or 0% APR with
Check your purchasing powerWhat 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.

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.

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.

1. How do total-body ellipticals engage the upper body?
Moving handles sync with pedals to work arms, shoulders, and core.
2. What power requirements exist?
Most total-body ellipticals are self generated, while others require a standard 110 V outlet. None require a 20 amp outlet.
3. How often should I lubricate the machine?
Apply a light silicone lubricant to moving components every 6 months.
4. What financing and warranty options apply?
Same financing as all other cardio; new units carry full OEM warranty, remanufactured include Build A Gym's 1 year guarantee. Extended warranties available at checkout.
