The reason this is important is that chains and bands give you the ability to develop explosive strength.
So instead of benching with high weight and slow velocity (maximal strength), or low weight with fast velocity (speed), you can work in the middle of the graph and accelerate the bar in both the lowering and raising phases of the movement.
So at the top where force is high and velocity is low, it is considered maximal strength.
As you work down the graph, strength-speed is next.
NIFS has recently updated the weight room, including seven new half racks.
Each rack has lower band pegs, and almost all of the racks have chains on the hooks at the top of the rack.
I hope this post answers your questions on whether this type of training is right for you.
