Hoist Leg Extension - RS-2401 Platinum

Hoist  Leg Extension - RS-2401 Platinum

Dynamic adjustment is the essence behind the ROC-IT line from HOIST. Using ROX technology, the user becomes an integral part of the exercise by continuously adjusting the position of the user with the movement of the exercise arm. As a result, the ROC-IT line embodies a unique training experience that achieves the unrestricted joint movement and core activating benefits of functional training coupled with the stabilizing benefits of machine-based equipment. Try it out for yourself and experience the ride of the ROC-IT line!

What our Experts Think

• Elite Quad Isolation Platform: The HOIST RS-2401 Platinum Leg Extension is a commercial-grade selectorized machine engineered for precise quadriceps development with smooth, controlled resistance.
• ROX Dynamic Movement Technology: Uses HOIST’s ROC-IT system to continuously adjust the user’s position during each rep, creating a more natural knee extension path and stronger quad activation with reduced joint stress.
• Biomechanically Optimized Motion: Begins in an upright position and subtly rocks backward through the movement, improving range of motion while maintaining proper hip and pelvic alignment for better quad loading.
• Joint-Friendly Design Focus: A self-aligning roller pad reduces ankle stress while guiding movement, helping protect the knees and lower back during heavy training sessions.
• Adjustable for All Users: Gas-assisted adjustable back pad accommodates different leg lengths, ensuring consistent positioning and comfort in commercial gym environments.
• Heavy Commercial Build Quality: Built for durability with a ~623–665 lb machine frame and 270 lb weight stack, designed to handle continuous high-traffic usage.
• Premium Training Feel: Delivers a smooth, stable resistance curve that supports both rehabilitation-style controlled reps and heavy hypertrophy training.
• Expert Verdict: A top-tier leg extension machine for serious facilities that prioritize quad isolation, biomechanical safety, and long-term commercial durability over simple home-gym functionality.

Q&A

Maintenance Tips

• Daily cleaning: Wipe pads, seat, and frame after use to remove sweat and prevent upholstery wear and corrosion.
• Inspect ROC-IT motion system: Ensure the rocking seat and lever arm move smoothly without noise, looseness, or sticking.
• Check cables & weight stack: Inspect for fraying, uneven travel, or resistance issues; keep the stack and guide rods clean.
• Lubricate guide rods & bushings: Use PTFE/silicone lubricant periodically for quiet, low-friction operation.
• Tighten hardware: Regularly check bolts, pivot points, and seat adjustments to maintain stability under load.
• Pad care: Clean vinyl pads with mild soap only—avoid harsh chemicals that damage upholstery.
• Keep alignment true: Ensure machine is level so biomechanics and resistance path remain consistent.
• Periodic inspection: In high-use gyms, check bearings, pulleys, and pivots for wear and replace if needed.
