Well, I got them, and they are sturdy, my shorter barbell fits, but I have to adjust the stands just right to make sure I have a good amount of room on each side. They actually work great for straight chest presses, but on an incline it is a little awkward, I have to sort of position them in front of me, keep my hand grip no more than shoulder distance, and then slide out from under it after I put the bar back on the racks. I think they would work much better with a slanted step instead of a bench, so there is more room to raise my arms. But I don't have the slanted risers.
So I'm not in love with these, but I really think part of my problem is this short dumbbell. But I just have stop buying stuff, so I'll just make this work.
I read on other boards, guys are using these for squat racks at the highest height, but you have to be in a pretty low squat already to start off and finish, so I'm not so sure about that.
