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: 46" × 40" × 55" 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.

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.
-
Wear parts replaced
Belts, cables, bearings, bushings, grips and safety-critical hardware are replaced as standard, whether or not they still have life in them.
-
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.

Commercial-grade equipment, inspected and supported by warranty.
The Hammer Strength Select Back Extension strengthens the posterior chain with a five-position adjustable start, ergonomically shaped lumbar pad aligned to the axis of rotation, two non-slip foot platforms, and a 295 lb selectorized stack - the lumbar pad's alignment to the rotation axis is the critical fit specification: it positions the user so the lower back extends through the correct arc rather than pivoting from the wrong point, which is what causes lumbar stress on improperly set back extension machines. The five-position start accommodates different torso lengths and range-of-motion preferences, and the two foot platform positions further expand the fit range across users of different leg lengths.
Smooth selectorized resistance covers rehabilitation through advanced lower back loading. 295 lb stack on a 560 lb commercial frame, 46" × 40" footprint, 300 lb max user. Remanufactured.

Lumbar Pad Aligned to Rotation Axis - Correct Extension Arc
The ergonomically shaped lumbar pad is positioned in relation to the machine's rotation axis - ensuring the lower back extends through the correct arc rather than pivoting from the wrong point. Incorrect axis alignment on back extension machines is the primary cause of lumbar stress during the exercise, making this the most important fit variable on the machine.
5-Position Start · 2 Foot Platforms · 295 lb Stack
Five start positions accommodate different torso lengths and range-of-motion preferences. Two non-slip foot platforms expand the fit range across users of different leg lengths. 295 lb selectorized stack covers posterior chain training from rehabilitation through advanced progressive loading.
