The variable resistance provided by the chains may limit their ability to improve force production in untrained athletes, suggesting that a strength/stability pre-requisite may be required to identify their efficacy for a particular athlete.To add to this, because there is uncertainty with how much additional load is applied to the barbell by the chains during an exercise, not only is selecting appropriate chains a difficult task, but monitoring the load becomes even more complicated.Although chain-resistance training has become very popular, there is still a significant lack in the theoretical understanding of this training modality.Having said that, it appears that accommodating loads of 20% of 1RM may be sufficient for improving force production in trained, but not untrained athletes, and that this is accompanied with reduce barbell velocities.This produces joint angle range of motion-specific and and velocity-specific adaptations, as well as greater improvements at the endurance end of the strength-endurance continuum.describes how the externally-applied force changes throughout the range of motion of the exercise.So at the top where force is high and velocity is low, it is considered maximal strength.

Traditional planks, side planks, squats and lunges are also in this category as the load is constant throughout the movement of the exercise.Several people have asked why you would ever need the band pegs or chains to do your everyday squat or bench.In this post, I cover what accommodating resistance is and the benefits of using this form of training.As a result, Table 1 provides a simple ‘guide’ to the mass-displacement relationships of a variety of chains, and is also downloadable and printable for use in gym facilities.When an exercise is supplemented with either chains or elastic bands, they cause a ‘variation’ in the load being lifted throughout the range of movement – hence the name ‘variable resistance training’. length-load) relationship, simply meaning the higher the chains are lifted, the more weight that is added (Figure 1).
