Leveraging a novel cam-based resistance system, these train units present a variable resistance all through the whole vary of movement. This implies the resistance will increase because the muscle strengthens throughout contraction, offering a extra constant problem and arguably selling better muscle fiber recruitment in comparison with conventional free weights or weight stack machines. An instance could be a bicep curl machine the place the resistance is easily elevated in the course of the lifting portion of the train after which easily decreased in the course of the decreasing portion.
This revolutionary strategy to power coaching, initially popularized within the Seventies and 80s, aimed to optimize resistance coaching by carefully mimicking the pure power curve of muscular tissues. The meant profit was improved power features, decreased joint stress, and a extra environment friendly exercise expertise. This expertise considerably impacted the health business and stays related at present, influencing the design of many fashionable resistance machines.
