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: 59" × 40" × 56" tall

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.

Product details
Commercial-grade equipment, inspected and supported by warranty.
The Cybex Eagle NX Back Extension uses a contoured lumbar pad with an adjustable start position — the contoured pad conforms to the lower back's natural curvature to maintain spinal alignment through the extension arc, and the adjustable start position sets the degree of flexion at the beginning of the movement to match each user's range of motion and rehabilitation requirements. A gas-spring-assisted seat adjusts smoothly between users without manual cranking.
Selectorized resistance delivers controlled, progressive loading for the erector spinae on an 827 lb Eagle NX commercial frame — one of the most substantial back extension frames in the commercial selectorized market, 59" × 40" footprint. Remanufactured.

Key features
Contoured Lumbar Pad & Adjustable Start Position
The contoured lumbar pad conforms to the spine's natural curvature to maintain alignment through the extension arc. The adjustable start position sets the degree of initial flexion for each user's range of motion — tighter for full-range lumbar work, wider for rehabilitation or limited-mobility users.
Gas-Spring-Assisted Seat
Gas spring assistance makes seat height adjustments effortless and fast — no manual cranking, smooth repositioning between users of different heights in high-turnover commercial environments without interrupting training floor flow.
827 lb Eagle NX Commercial Frame
The 827 lb frame is notably substantial for a back extension machine — Eagle NX construction standard throughout, built for sustained high-frequency commercial use with the structural integrity and finish associated with the Eagle NX line.
