BUILT Strength Fractal Series Leg Extension / Leg Curl (New)

Description

The BUILT Strength Fractal Series Leg Extension / Leg Curl is a commercial-grade combo machine that delivers complete lower-body isolation training from a single selectorized station. Designed for gyms, training facilities, and serious home setups, it targets the quadriceps with leg extensions and the hamstrings with leg curls - all without touching the weight stack when switching between exercises. The quick-switch mechanism keeps workout intensity high and transitions seamless, making it ideal for supersets and circuit-style programming.

Weighing in at 691 lb, this machine is built to stay planted and stable under maximum loading in both exercise positions. Independent adjustments for the seat, backrest, and leg rollers ensure proper alignment for users of all sizes, while unilateral training capability lets athletes address strength imbalances one leg at a time. Whether you're outfitting a commercial facility or building a dedicated training space, the Fractal Series delivers the engineering and versatility to match serious performance demands.

Key Features

  • Quick-Switch Mode Transition: Converts between leg extension and leg curl without changing the weight stack setting - keeps training intensity high and eliminates lengthy reconfiguration between exercises.
  • Unilateral & Bilateral Training: Both exercises can be performed one leg at a time or with both legs, enabling targeted correction of strength imbalances alongside standard progressive loading.
  • 300 lb Selectorized Weight Stack: Pin-select stack covers the full training range for both leg extension and leg curl exercises - suitable for beginners through advanced athletes.
  • 691 lb Commercial-Grade Frame: Exceptional structural mass keeps the machine stable and grounded under maximum loading in both extension and curl positions.
  • 11-Gauge (3mm) Steel Frame: Heavy-duty steel construction provides the rigidity and durability expected of institutional-grade training equipment built for daily use.
  • Three Independent Adjustment Points: Seat, backrest, and leg rollers each adjust independently to dial in proper hip angle and leg alignment for any user before the first rep.
  • Targets Primary & Secondary Muscle Groups: Leg extension works the Quadriceps and Rectus Femoris; leg curl targets the Biceps Femoris, Semitendinosus, and Semimembranosus, with secondary activation of the Gastrocnemius, Glutes, and Hip Flexors.
  • Dimensions 61" x 40" x 58": Compact commercial footprint that fits efficiently into gym floor plans without sacrificing functionality.
  • 1-Year Parts & Labor Warranty + Lifetime Frame: Coverage begins on the date of delivery, with extended protection plans available for added peace of mind.
  • Brand New Condition: Ships factory-crated with full manufacturer warranty - current-model equipment, never used.

FAQ

Does this machine require floor mounting?

Floor mounting is not required. The machine's 691 lb commercial-grade frame provides substantial stability on its own. That said, placing it on a level surface and ensuring at least 3 feet of clearance around the machine is recommended for safe use and comfortable access during workouts.

How does the quick-switch mechanism work between leg extension and leg curl?

The quick-switch mechanism allows you to transition from leg extension to leg curl mode - or vice versa - without resetting or re-pinning the weight stack. This means you can move directly from one exercise to the other at the same resistance level, making it ideal for supersets, drop sets, or high-intensity circuit training without any downtime between movements.

Can I train one leg at a time on this machine?

Yes. Both the leg extension and leg curl functions support unilateral (single-leg) training. This is particularly useful for identifying and correcting left-to-right strength imbalances, supporting post-injury rehabilitation protocols, or simply adding variety and intensity to your lower-body training program.

How is this machine delivered, and will it be assembled for me?

The machine ships freight on a pallet inside a factory crate, along with an assembly manual. Standard delivery is driveway delivery, where the freight carrier uses a liftgate to lower the pallet to your curb or driveway - moving it inside is the customer's responsibility. An inside delivery and assembly option is available at checkout, where a delivery team brings the equipment into the room, assembles it, tests it, and removes all packaging.

What does the warranty cover, and how long does it last?

All new BUILT Strength equipment includes 1 year of parts and labor coverage, plus a lifetime frame warranty. Coverage begins on the date of delivery. Extended protection plans (adding 1 or 2 additional years of parts and labor) are available for purchase at checkout. Warranty service is available nationwide.

Is this machine appropriate for a home gym, or is it strictly commercial?

While the Fractal Series is built to commercial specifications - 11-gauge steel frame, 691 lb machine weight, 300 lb selectorized stack - it is equally well-suited for a dedicated home gym where quality and longevity are priorities. If you have the space (61" x 40" footprint) and want a machine that will perform reliably for decades, this is a sound investment for serious home training environments as well as professional facilities.
