I have a black olympic "bench" bar that I use when "benching". It feels fine to me, but when I go lift somewhere else, my bench strength feels about 15 lbs. stronger. The bench bars I use when not at home are always chrome. I tried to google it, to find a different style.(maybe it supports more weight?)but wondered if the bar I have is a heavier bar than normal? It is identical looking other than it is a steel color not chrome. I don't have a home scale to check it.

Thanks, Arnold in training.
