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: 61" × 40" × 58" tall

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 Fractal Series Seated Leg Curl isolates the hamstrings in an upright seated position that maintains correct lumbar support and reduces lower back strain throughout the curl — the ergonomic seat design keeps the pelvis positioned correctly from start to finish, preventing the hip hike and lower back involvement that poorly designed seated curl machines allow. Adjustable backrest and ankle rollers allow precise setup for any user's leg length and preferred starting position.
A 300 lb selectorized stack delivers consistent, fluid tension through bilateral or unilateral leg curls, and a 680 lb heavy-duty commercial steel frame provides the structural stability needed for serious hamstring training under sustained professional loading. New.

Key features
Ergonomic Seated Position — Lower Back Support
The ergonomic seat design maintains correct lumbar support and pelvis positioning throughout the curl — preventing hip hike and lower back compensation so the hamstrings perform the full work of the movement without strain.
Adjustable Backrest & Ankle Rollers
Backrest and ankle rollers both adjust independently for any user's leg length and preferred position — keeping the knee joint aligned with the pivot and the hamstring loading consistent through the full curl range of motion.
Bilateral & Unilateral Leg Curl
Standard bilateral hamstring curling alongside single-leg unilateral work — enabling left-right strength balance work and corrective training in the same station as standard bilateral progressive loading.
300 lb Stack · 680 lb Commercial Frame
A 300 lb selectorized stack covers light activation work through serious progressive hamstring loading. The 680 lb heavy-duty commercial frame delivers structural stability for sustained high-volume professional leg curl training.
