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: 62" × 40" × 64" tall
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 Life Fitness Signature Series Calf Extension delivers 390 lb selectorized stack with 5, 10, or 15 lb increment options, gas-assisted seat adjustment, military-spec 7×19 strand cable, sealed-bearing fiberglass pulleys, and 11-gauge steel frame — the three increment options (5, 10, or 15 lb) are the standout specification for a calf machine: the calves are typically trained at higher rep ranges than other muscle groups, and the difference between 5 lb and 15 lb increments matters significantly at the lighter end of the stack where most users work. A 5 lb increment system allows fine-grained progressive overload in the 20–50 lb working range that many users operate within; a 15 lb increment at the same range represents a 30% jump between steps, which is too coarse for consistent progression. The 390 lb stack accommodates the full range from light rehabilitation through heavy progressive calf loading.
Gas-assisted seat adjustment for quick setup. Thermo rubber non-slip hand grips. 7×19 mil-spec cable construction. Sealed-bearing pulleys. Electrostatic powder coat. 700 lb total unit weight (includes 390 lb stack), 62" × 40" footprint. Remanufactured.

5, 10, or 15 lb Increments · 390 lb Stack — Fine-Grained Calf Progression
Three increment options accommodate different progressive loading needs — 5 lb increments enable fine-grained overload in the lighter working ranges where most calf training occurs, where a 15 lb jump would represent a 30%+ step between settings. 390 lb stack covers the full range from rehabilitation through heavy progressive calf loading without hitting a ceiling.
Military-Spec 7×19 Cable · Sealed Pulleys · 11-Gauge Steel
7×19 strand lubricated nylon-coated cable — seven groups of nineteen wires — provides durability and flexibility for the calf extension range of motion. Fiberglass-impregnated nylon pulleys with sealed bearings maintain smooth operation without maintenance. 11-gauge steel frame with electrostatic powder coat handles the loading and repetition demands of commercial calf training.
Gas-Assisted Seat Adj. · Thermo Rubber Grips
Gas-assisted springs make seat adjustment quick and effortless between users of different heights — no manual resistance to overcome during repositioning. Thermo rubber hand grips are non-absorbing and wear-resistant, maintaining grip security through sweat without degrading over high-rep commercial use.
