What is your opinion about lifting chains? Powerlifters like them, but are they good for increasing muscle mass?
Lifting chains works for bodybuilders for three reasons:
- They help match the resistance curve of an exercise with the strength curve of a muscle;
- They prolong the time under tension of an exercise;
- They increase the intensity of an exercise. Let’s explore.
A strength curve, or force curve, is a mathematical model that represents how much force an individual can produce at a specific joint angle. This is in contrast to a resistance curve, which is how difficult an exercise is at specific points of the exercise. There are three basic types of strength curves: ascending, descending, and ascending-descending.
An ascending strength curve refers to being able to display more force when you extend a joint, a descending strength curve refers to being able to display more force as you flex a joint, and an ascending-descending strength curve means you can display more strength at the midrange position of a joint. Lifting chains are best used for exercises that involve ascending strength curves so that the weight feels lighter as you get close to the end range of the exercise. Examples include squats, deadlifts, bench presses, and military presses. / www.imbafit.com
