The Cybex Prone Leg Curl selectorized strength line is the evolution of superior technology combined with a passion for fitness. There is no comparable strength line in the industry – Eagle is beyond the other’s best. Starting with exhaustive research in human biomechanics and applying the Cybex heritage in sports medicine, Eagle is the ultimate way to “faster fitness results”. The Cybex-pioneered optimal ergonomic design creates a more comfortable exercise. The forearm pads are positioned to encourage the user to pull into the pads to a neutral spine throughout the movement reducing the possibility of hyper-extension. Using forearm pads to support the upper body allows for an open space for the users face and head promoting better gym hygiene. Offset input arm allows for the lower leg pad to adjust with minimal effect on the starting angle of the knee. In combination with proper pivot location, this allows the use of a contoured pad for improved comfort.The innovative designs on the Prone Leg Curl make positioning the tibia pad an intuitive, virtually effortless, one button adjustment resulting in easily accessible and easily adjustable machines. All strength training is the application of stress. Cybex designs products to apply the appropriate amount of stress to produce the desired training effect but does it in a way that reduces the chance of injury.
