Nevertheless,derivative technologies continue to flood the marketplace.
Variable Resistance Training (VRT), sometimes called accommodating resistance, is a type of training that I’ve been interested in for a while now, and which has been a part of the powerlifting community for even longer.
VRT is what you’re seeing when a lifter adds elastic bands or chains to the bar before a lift.
This has the effect of increasing the resistance toward the end of the concentric phase of the lift.

Resistance can take one of two forms in athletic training: constant resistance or variable resistance.
Constant resistance is a form of training where the resistance directed against the target muscle or muscle group does not vary through the range of athletic movement.
VRT is a relatively new aspect of training, and as such has not been well studied.
The basis of its effects and effectiveness are largely anecdotal.
There is a point, as the dumbbell is lifted, where the resistance on the muscle is greatest; at the movement before and after that maximal point, the resistance force is much less.
