These collars are a hit or miss, depending on whether you care to preserve the sleeves of a barbell that you'll use them on from scratches. Because these collars WILL scratch up any sleeves on which they are tightened. I use them on my old Titan axle bar, which is my dedicated "beater" and landmine bar. I have some other bars that I don't care to preserve the pristineness of their sleeves, and these are fair game there, too. Once that caveat is out of the way, the benefit of these collars is that they hold pretty tightly. And because they're all metal, they are virtually indestructible.

Very portable and cost effective. Drink safety for the masses!

Great for making visitors to your gym think that you're pretty strong. If you actually are strong, or like to train strongman-style, this would be a good item to have in your equipment toolkit. I bought mine off of Craigslist for $20 from a dear lady who subleased an apartment to a college guy, who apparently used it to transport beer to frat parties. I've alternately filled it with water and sand and did "functional" movements with it, e.g. throw for height or distance, clean and press, loaded carries. Few sessions with the keg makes me appreciate the good ole' barbell all the more!

I survived the most rigorous certification process in my life, but it was well worth it. Get it, if you want people to know that your gym is a place where they can get strong, stay strong, and learn how to use their strength.

These give you the benefit of training with a pinch block coupled with the versatility of using a dumbbell. They really work your grip, especially the pinch grip that heavily involves the thumbs. There are two widths you can choose from, 2.5" and 4", which offers greater versatility than Titan's beam ("Saxon") barbell, which is 3" x 3". My only complaint is that the sleeves could have been designed better so that the powder coat of the inmost sections do not get scuffed when loading and unloading plates. The sleeves are also narrower than the standard olympic sleeves, so you'll need a collar adapted to specialty bars.

This BBC (Big Black Curl-bar) is a distant cousin of the legendary chrome hex-bolted ez curl bar, the one visited by the bar fairy. It also bears similarity to an axle bar in that it boasts a thicker diameter (around 2") - and every guy knows what a big difference an inch can make. As such, it stimulates forearm gains even as one is trying to grow their biceps. For anyone used to using the chrome ez curl bar, once they go big and black, they might never go back.

My Abmat pad sits quietly in the corner of my gym, guilting me for avoiding sit ups. Luckily for me, it has other uses, e.g. for greater ROM during one-arm dumbbell preacher curl via an incline bench, comfortable floor cushion during seated cable rows, a pillow during naps in the gym. The pad is incredibly resilient and seem to return to its original shape, no matter how many times it gets squished during my "off-label" uses. As such, it's an ANTI-memory foam. One day I'll succumb under the mounting pang of guilt and use it for sit ups. Finally.

Legend has it, this bar has existed since the dawn of time, like the monolifts in 2001: A Space Odyssey. Some theologians believe that there was a "gap" between Genesis 1:1 and Genesis 1:2 - and I believe that that is when this bar may have been created. After God said, "Let there be light," he said "Let there be gains" and - poof! - this bar materialized ex nihilo. Its mode of travel is mysterious, but some surmise that it's transported via bar fairies through wormholes, ending up in various garage - and even basement - gyms across planet earth. Given this pedigree, this bar is easily God-tier. Epilogue: Oh, the ez curl bar in my hands - but if I could understand what you are, bolt and all, I should understand what God and man is.
