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
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.
Add before it ships
Before the freight bookingCoverage and accessories have to go on the same booking as the machine. Add them here and they travel together.

I was thinking about getting Ozempic, but I’m not in the mood to go blind yet. So I decided I’d do it the old fashioned way and called CTX.

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!

Absolutely best in business! Not only is Dillon just genuinely a great human being, he’s real and honest. Loved everything I’ve gotten from him and the team. I’m about 10-15 pieces in deep with him and not stopping anytime soon! Absolutely recommend hitting these guys up for home/commercial equipment. New or refurbished!

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.

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 to 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.
Primary muscles targeted
Gastrocnemius Soleus
Secondary muscles
Tibialis Posterior Peroneals Flexor Hallucis Longus
Key features
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.
