I was looking for a different barbell to do barbell curls, I already have a straight bar, which is the normal one, but that does your wrists in and it is much harder to do proper curls. The work close grip bar can be used for doing tricep curls, bi cep curls and you can use it for the inner biceps and outer biceps. So, it's multi functional. Also, the bar on it's own has a very good weight, so you already start off with about 5kg weight before adding any weights to the bar. I find this bar works very well for me and i would recommend anyone to buy this bar, if anybody needs help with deciding to buy this product just ask me a question and i will respond as soon as possible.
