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: 50" × 41" × 64" tall
Weight Stack: 160 lb
What 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.
Holiday Returns & Exchanges
Holiday return window. For new equipment ordered November 11 through December 31, 2026, you may request a return or exchange until January 31, 2027, or 30 days from delivery, whichever is later. All other terms apply, as described below.
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.

CTX/ Build-a-Gym absolutely CRUSHED IT! I had been struggling with numerous manufacturers trying to get a seated leg press/extension that’d ship to Alaska. When I found CTX, they went above and beyond to get my Fractal packaged and shipped with no hassle. I HIGHLY recommend these folks to anyone looking for solid commercial quality equipment for their home.

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!

Product details
Commercial-grade equipment, inspected and supported by warranty.
Quick answer: A leg extension leg curl combo trains the quads and the hamstrings on one selectorized machine, so you get two leg isolation stations in the space of one. The BUILT Strength Compact Series Seated Leg Extension / Leg Curl switches between movements with a quick-adjust mechanism, keeps the same weight stack, and fits a 50 x 41 inch footprint. It ships new from Build A Gym with nationwide delivery and warranty-backed support after the sale.
The BUILT Strength Compact Seated Leg Extension / Leg Curl covers quad isolation and hamstring development from a single station - a quick-adjust mechanism transitions between seated leg extensions and seated leg curls without leaving the machine or changing the weight stack. Both movements use the same comfortable padded seat and rollers, keeping setup fast and training flow uninterrupted between exercises.
Smooth selectorized resistance maintains consistent tension through both the extension and curl arcs, and a compact 50" × 41" footprint at 529 lb delivers a complete dual-function leg isolation station in the space of a single machine. Contact us for full weight stack specifications. New.

Key features
Quick-Adjust Mode Transition
A quick-adjust mechanism transitions between leg extension and seated leg curl without changing the weight stack or leaving the seat - fast transitions that maintain training momentum and allow easy antagonist-pair leg programming.
Padded Seat & Rollers - Joint-Friendly
Comfortable padded seat and leg rollers keep the knee joint correctly positioned for both exercises - smooth, consistent contact through the extension and curl arcs for joint-friendly quad and hamstring isolation.
Smooth Selectorized Resistance
Smooth pin-select resistance delivers consistent tension through both movement arcs - controlled quad loading on the extension, controlled hamstring loading on the curl, with fast weight changes between sets.
Compact Dual-Function Frame
A 50" × 41" footprint and 529 lb commercial-grade construction deliver both leg extension and leg curl training in the space of a single machine - ideal for home gyms and commercial spaces where floor space is a priority.

Buyer questions
Is a leg extension leg curl combo as good as two machines?
For most home gyms and small facilities, yes. You lose the ability for two people to use both at once, but you save floor space and budget. Busy commercial floors often still run separate stations.
How do you switch between leg extension and leg curl?
Use the quick-adjust mechanism on the machine. You stay in the seat and the weight stack stays the same, so moving from extensions to curls takes seconds.
Are leg extensions bad for your knees?
Not when loaded sensibly with good setup. Line the knee up with the pivot and control the lowering. Our guide covers the common myths.
