Excellent kit for the gym back
Wether you are pressing over head, benching or want that bit of wrist support on squatting these are the answer. When used correctly these things are great, bare in mind they wont be comfortable. Dont be the one walking around the gym with them on the whole session because that means they are tight enought to actually assist you.
These things cast your wrist so securely you can definitely get a new PR once you get used to them.
