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.

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 Hammer Strength Back Extension features an angled hip pad for proper spinal alignment, lower leg rollers for secure anchoring, and deformation-resistant foam padding on an 11-gauge steel frame — the angled hip pad is the key ergonomic specification on any back extension station: it positions the hip joint at the correct flexion angle so the erector spinae, glutes, and hamstrings extend through their full functional range without the lumbar spine going into harmful hyperextension at the top. Lower leg rollers keep the user anchored through the full extension without the lower body shifting under load.
Deformation-resistant foam maintains comfort and pad geometry through sustained high-traffic commercial use without compressing flat. 244 lb 11-gauge steel commercial frame, 59" × 28" footprint, 350 lb max user. Remanufactured.

Key features
Angled Hip Pad — Correct Spinal Alignment
The angled hip pad positions the hip joint at the correct flexion angle so the erector spinae, glutes, and hamstrings extend through their full functional range — preventing the lumbar spine from going into harmful hyperextension at the top of the movement, which is the most common back extension setup error.
Lower Leg Rollers · Deformation-Resistant Foam · 11-Gauge Frame
Lower leg rollers anchor the user through the full extension without the lower body shifting under load. Deformation-resistant foam maintains pad geometry through high-traffic commercial use without compressing flat over time. 11-gauge steel frame handles sustained daily use in professional training environments.

3. Are flat benches compatible with Smith machines?
Yes—most flat benches fit under Smith bars; verify width in product specs.

New benches: OEM warranty; remanufactured: 6–12 month Build A Gym Guarantee.
5. What delivery options are offered?
Ground parcel shipping for small benches; curbside freight for commercial models.
