I have a super curl bar and its great, but with the close grip U part of the bar it's unthreaded. I like doing my regular curls with a wider grip and my reverse curls with a close grip. Is there some sort of gloves I can buy? When I do a reverse wide grip I feel like I want to use more back for some reason, but if I go close I don't have that issue, but since the bar is unthreaded there I loose my grip when my hands get sweaty.
