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: 57" × 42" × 64" 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.

The Life Fitness Signature Series Leg Extension uses a 100-degree angle between the seat and back pad — this specific geometry places the hip in slight flexion at the start of the extension, which is the position where the rectus femoris and quadriceps produce maximum contractile force. The 100° seat angle is the key design specification that enables full quadricep contraction at the top of the movement where many leg extension machines fall short. All adjustments are accessible from the seated position, eliminating the need to stand and reposition between set adjustments.
A 290 lb selectorized stack with magnetic selector pin and 5/10/15 lb increment options on a 640 lb Signature Series commercial frame. Gas-assisted seat adjustment, 11-gauge steel with electrostatic powder coat, military-spec cables. 57" × 42" × 64". Remanufactured.

100° Seat Angle — Full Quadricep Contraction
The 100-degree angle between the seat and back pad places the hip in slight flexion at the start of the movement — the position where the quadriceps produce maximum contractile force, enabling full quad contraction at the top of each rep where many leg extension machines lose loading.
Gas-Assisted Seat Adjustment — Seated Operation
Gas-assisted springs make seat adjustments quick and effortless. All adjustments are accessible from the seated position — users set up correctly without standing and repositioning, keeping training flow uninterrupted in high-turnover commercial environments.

290 lb selectorized stack with magnetic selector pin and 5/10/15 lb weight increments. 7×19 strand nylon-coated military-spec cables with fiberglass-impregnated nylon pulleys and sealed bearings. 11-gauge steel frame with electrostatic powder coat finish.
