If you work out at home with a regular olympic bar go to the hardware store and buy the foam pipe insulation and 2" pvc pipe. Wrap the insulation around the bar and then cut the pipe with a Dremel tool length wise into two sections. Place it over the foam and secure it with duct tape to keep it together or tennis racket tape. It cost me less than $10 and 15 minutes of my time. I have been using it for two weeks and I love it. I’ve already seen great results from it. It’s not pretty but it is very functional as a thick bar.
