i think this is what he was asking for...
its like using bands only more hardcore
Yep.
I think bands are a little more practical, especially if you train in a facility that frowns upon storing & attaching big, clunky, noisy, rusty chains to their equipment.
I’ve never used either, but most power-lifters I’ve talked to over the last few years claim they prefer the bands.
I have known a few bb’er types who implemented power moves into their training - bands/chains being one of them.
Same goes for lockouts done inside a power rack
(compare with board-presses), as well as rack deads.
Even if training strictly for aesthetics, I think it’s wise to incorporate some power-lifting principles on occasion to switch things up and help break through some plateaus.
