Works great, definitely would recommend!

Works great! Our set up doesn’t allow us to use an another bar to attach it too, so it’s a little big for what we use, but we used a small towel and it fits great! Comfortable and supports weight well.

I use this now for myself and my clients and the glute isolation using this is perfect.

Please be advised that this pad only fits a Olympic bar and NOT the bar on a smith machine

Not safe for heavy hip thrusts, so I returned it. Neat idea, but doesn’t work.

I'll be honest. After requesting this through Vine, I regretted it. The $50 estimated value is a high and I really didn't expect a lot from the product. After receiving it and giving it a bit of testing, I admit it is better than expected. I still think $50 for a dense piece of foam with a groove is to much. In my opinion it should be closer to $20, but the product itself is nice.
It feels good against the back and the way it rotates as you thrust your hips feels very fluid. The big drawback for me is that the lowest setting on my squat rack is several inches too high for me. I'm 5'7". With a different squat rack or taller person, that may not be a problem. It's not an impossible problem to solve. I can put the bar on the ground with some large plates on it, but against the rack or I can sit on a plate like the image shows.
I will have to experiment and see which I prefer. Another drawback is that you really need 2 bars. You could use body weight, dumbbells, a curl bar, kettlebell, or a plate but ideally you need a 2nd barbell and that drastically increases the cost of this setup.
Overall it is a nice piece of foam and a cool idea, but I don't know how economical it is vs other options such as simply investing in a high quality bench with vertical adjustments.

This is a really useful product for a home gym to make barbell hip thrusts easier than the usual position of placing your upper back/shoulders on a weight bench. Because this rotates as you lower and raise, it allows for a fuller range of motion. The foam material it's made of is VERY dense and firm, which provides stability.
I unfortunately didn't get a rack for my home gym setup that has hook attachment holes low enough to place the barbell where I'd like when using this, but I'm still able to make do with it. (If anyone knows of any longer J-hook attachments that would allow you to use a higher peg hole for a J-hook that's positioned lower than normal from that peg, would love to hear about it! Longest I've found so far is 6 inches from peg to hook.)
Only feedback I would have on this is that the edges of the pad can feel a little hard as I press against it in a way that sometimes isn't comfortable. Could be a user issue (either in terms of form or in terms of sensitivity) but the foam really is hard and dense, so I'd love it to have slightly rounded edges for comfort where it presses against my back. Other than that, though, this is great.
