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: 48" × 63" × 58" tall
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.
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!

Product details
Commercial-grade equipment, inspected and supported by warranty.
The BUILT Strength Fractal Series ISO Lateral Bicep Curl uses independent lever arms - each side curls separately on its own path, preventing the stronger arm from assisting the weaker and ensuring equal loading on both biceps through every rep. Ergonomic arm pads brace the upper arms throughout the curl, removing shoulder swing and keeping each rep strict regardless of loading or fatigue level.
A natural curling path with consistent selectorized tension through the full arc delivers smooth, controlled bicep loading from full extension through peak contraction. Adjustable seat height positions the elbow correctly on the arm pad for any user, and the 175 lb stack covers warm-up through serious progressive bilateral and unilateral arm development. New.
Primary muscles targeted
Biceps Brachii Brachialis
Secondary muscles
Brachioradialis Forearm Flexors
Key features
ISO Lateral Independent Arms
Each arm moves on its own independent lever - the stronger side cannot assist the weaker through bilateral curls, ensuring equal loading on both biceps simultaneously for balanced development and imbalance correction over time.
Ergonomic Arm Pads - Strict Isolation
Ergonomic arm pads brace both upper arms throughout the curl - removing shoulder swing, elbow flare, and body momentum so the biceps perform the full work of every rep from full extension through peak contraction.
Adjustable Seat Height
Seat height adjusts to position the elbow correctly on the arm pad for any user size - keeping the pivot point accurate for consistent curl mechanics and maximum bicep loading across all users.
Unilateral & Bilateral Curling
Single-arm unilateral curls for focused isolation and imbalance correction, or both arms simultaneously for standard bilateral bicep development - both options from the same 175 lb selectorized station without any reconfiguration.

How assembly works
1. What are the exact dimensions and space requirements for this machine?
This machine measures 48 inches front to back, 63 inches wide, and 58 inches tall, with a 21 square foot footprint. We suggest allowing extra clearance around it for comfortable use and movement.
2. How much weight can I load for bicep curls?
It features a 175 lb selectorized weight stack, adjustable in small increments using the pin selector.
3. What muscles does this machine target and how does it work?
It is designed for strict bicep isolation, primarily targeting the biceps brachii and brachialis, with secondary emphasis on the brachioradialis and forearm flexors. The independent lever arms allow for both unilateral and bilateral curls.
4. How does the ISO-Lateral feature benefit my training compared to standard bicep curl machines?
The ISO-Lateral design means each arm moves independently, so the stronger arm cannot assist the weaker side. This helps correct muscle imbalances and ensures equal loading for balanced development.
5. Is there an assembly manual included with this machine?
Yes, an assembly manual is available in the Assembly tab on the product page.
6. What warranty comes with this new machine?
This new unit includes the manufacturer warranty from BUILT Strength. You can also add extended coverage with BAG Care+ on the product page.
