Hoist Leg Curl - RS-2402 Platinum

Hoist  Leg Curl - RS-2402 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 hamstring training with intelligent motion design
  The RS-2402 Platinum Leg Curl uses HOIST’s ROC-IT® + ROX™ system to create a dynamic, joint-friendly curling movement that adapts to the user during every rep.
• Smarter biomechanics vs traditional leg curl machines
  Instead of a fixed seated position, the machine rocks the torso backward during the curl, helping maintain a posterior pelvic tilt for stronger hamstring activation and reduced lower-back stress.
• Reduced knee and ankle strain
  Features like a self-aligning roller pad and adjustable shin pad help guide a natural hinge motion, minimizing shearing forces on the knees and stress at the ankle joint.
• Constant tension through full range of motion
  The moving-seat design keeps resistance more consistent across the entire curl, improving muscle engagement compared to traditional fixed-path machines.
• Highly adjustable for different users
  Gas-assisted back pad and auto-adjusting lower support allow quick setup for varying leg lengths, making it efficient for busy gym environments.
• Commercial-grade durability and stability
  Built as a heavy-duty selectorized machine (~270 lb stack, ~636 lb frame), designed for continuous high-traffic gym use without performance drop-off.
• Platinum finish premium aesthetic
  The Platinum version adds a clean, modern commercial look while keeping the same biomechanics and resistance profile.
• Expert takeaway
  This is a high-end hamstring isolation machine focused on joint safety, natural movement, and consistent tension, making it ideal for serious strength training facilities rather than casual home setups.

Q&A
