This personal trainer that i met while working at an office earlier this year told me that he lifts weights using a thick bar that he made himself. so time goes by and i forget all about it, then i started lifting about a month ago again. Today was my rest day and i remembered what this guy said so i looked up fat Olympic bars and found out that they are expensive as fuck(around 500) so i was thinking about going to home depot and getting a metal pipe and welding it to my bar, which is way cheaper. but then i did some more research and found out about these "Fat Gripz" and after reading and researching them alot i'm pretty much sold, the benefits of these things seem to be pretty awesome, they probably are about the same price on what i would spend getting the bar welded, but it sure would be easier and less time consuming. have any of you tried these things, and how much strength have you gained while using them.
