What is one key benefit of using variable resistance in exercise equipment?

Using variable resistance in exercise equipment is highly beneficial because it allows for maximum muscle involvement throughout the entire range of motion during an exercise. Variable resistance systems are designed to accommodate the varying strength levels of muscles at different points in the movement. For example, muscles can exert more force in certain positions of an exercise than in others, so a variable resistance mechanism adjusts the level of resistance. This allows muscles to work most effectively and efficiently at every point in the movement, enhancing strength and performance.

Moreover, this tailored resistance can lead to improved muscle engagement and activation, which can result in better strength gains and functional adaptations. This aspect makes variable resistance particularly advantageous for strength training, as it can help target specific muscle groups effectively.

Other considerations, such as flexibility, injury risk, or the intensity of the workout, are not primary benefits of variable resistance; the focus primarily remains on optimizing muscular engagement through varying resistance levels during exercise.
