The Technology Behind the HOIST ROC-IT Sensation

In 2007 HOIST launched a line of strength training equipment using a new technology the fitness world had never seen. The HOIST Fitness ROC-IT line, first featuring selectorized machines and then the addition of plate loaded products, uses a unique rocking technology that moves the user as a whole rather than just targeted muscles.

“With its dynamically rocking technology, the HOIST ROC-IT line reveals numerous biomechanical and physiological advantages missing with traditional exercise machines,” says Fabio Comana, MA., MS., NASM CPT, CES & PES; NASCA CSCS, ACSM HFS, ACE CPT & LWMC; DCISSN, Director of Continuing Education, NASM. “This includes a dynamically-adjusted user positions to optimally align and maintain joint position throughout motion, This also reducing stress on joints, improves stability and provides a pre-stretch most machines o=don’t have.”

ROC-IT products capture attention and make strength training more enjoyable, but the foundation of the ROC-IT design isn’t based on appearance—it’s rooted in extensive biomechanical research. ROC-IT technology addresses the human body as a complete system, not as isolated groups of muscles. The movement designed in each ROC-IT product more closely mimics the way a body operates in everyday life, enhancing results and reducing risk of injury. Traditional machine-based exercise is muscle-centric and provides a stable platform, which helps beginners and casual users. But it comes at the cost of isolating individual muscles in a stable environment. Effective strength training challenges the entire Human Movement System, which has nervous, muscle and skeletal components working in harmony to achieve optimal results. This is where traditional machines fail.

Fixed machine design restricts natural movement, especially at the end of the range of motion. It forces unnatural positions that put unnecessary stress on the body, increasing the risk for injury. It’s not uncommon to see a user come out of the seat on a fixed machine at the end of the exercise motion. Why? Because the machine forces the user into an unnatural position—out of proper alignment. The machine is fixed, and because the user is not, he/she is required to adjust to the machine to complete the exercise. With the compromised biomechanical positioning in the end of the exercise motion in fixed machines, the body’s ability to safely and effectively control movement is diminished. ROC-IT products continuously adjust a user’s position, maintaining optimal positioning throughout the entire exercise range of motion. Essentially, the machine transforms to accommodate the movement of the human body. Effective strength training requires an efficient way to condition and challenge a body’s functional capabilities. It utilizes systems that promote optimal biomechanics throughout the full range of motion. It trains the body in a way that challenges and incorporates the body’s stability centers. Each ROC-IT machine is designed to continuously shift the user’s center of gravity to impose appropriate challenges to the Lumbo- Pelvic-Hip Complex (LPHC). This advanced exercise movement enhances core involvement and the number of LPHC muscles needed to stabilize the hips and trunk. ROC-IT products yield more stability, more strength applied to the exercise path, and more calories burned—for a more complete exercise.


  • They make the human body an integral part of the exercise, training it as a system, not isolated and disconnected parts.
  • They provide stable exercise platforms that help users maintain a natural range of motion and correct form without overloading or stressing joints.
  • They allow users to impose a “pre-stretch” that improves muscle activation and strength increases.
  • They reduce recovery time by eliminating awkward positions that compromise the body’s ability to rebuild.

Fitness facilities exist because of their members, and it’s imperative that owners install the safest and most effective equipment available. HOIST’s ROC-IT line is an industry leader when it comes to selecting equipment that minimizes risk during strength training exercise. When you add ROC-IT products to your facility, you’re not just installing machines designed and engineered with unique patented ROC-IT technology, you’re installing machines people can’t wait to use!
