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 New Means
Brand new, current-model equipment shipped in the factory crate with the full manufacturer warranty. Extended coverage is available at checkout.
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 BUILT Strength OG Series Plate Loaded Leg Extension / Seated Leg Curl switches between quad isolation and hamstring development via a quick-change pop-pin selector — no tools, no significant setup time between exercises. The transition is designed to be fast and intuitive, keeping training momentum high without a lengthy reconfiguration between movements.
A self-adjusting lower leg pad automatically maintains correct alignment through both exercises, and the adjustable back pad and start position settings accommodate any user size. A firm round thigh pad locks the body stable during curls to prevent hip lift and keep hamstring load consistent throughout the movement. Starting at 20 lb with plate-loaded resistance — warm-up through maximal loading with no stack ceiling. Two integrated weight horns keep plates organized on the unit. New.

Key features
Pop-Pin Quick-Change Between Exercises
A pop-pin selector converts the machine between leg extension and seated leg curl without tools — a fast, intuitive transition that keeps training intensity high without significant setup time between movements.
Self-Adjusting Lower Leg Pad
The lower leg pad automatically adjusts to maintain correct alignment through both extension and curl movements — reducing manual setup between exercises and ensuring proper positioning for every user without additional adjustment steps.
Firm Round Thigh Pad
A firm round thigh pad braces the leg during seated curls — preventing hip lift and keeping the hamstrings under consistent, direct load through the full curl arc without compensation from the hip flexors.
Adjustable Back Pad & Start Positions
Back pad and start position both adjust independently for any user size — setting the correct hip angle and range of motion for both exercises before the first rep begins and maintaining it throughout the set.
Plate-Loaded — 20 lb Starting Weight
Olympic plate loading with a 20 lb starting weight covers warm-up and technique work through to maximal loading — no stack ceiling, unrestricted progressive overload for serious quad and hamstring development over time.
