Why would you load the bar on the floor with bent rows if there is a rack you can load it on the jcups
(taking deep breath)
take from the rack, you now have to take a step back, bend forward with the weight, stop, do your set, and then stand back up with the weight when done.
take from the floor, I grab the bar stand up slightly, do my set, when I am done I just drop it.
I don't give two shits about the ease of loading when on j-cups.
Plus, I am not taking up space in the rack for someone squatting
