I was wondering why 405 on the SSB bar felt heavier than on Power-Bar. When I weighed it, it then made sense, 55 lb. bar...
LOL.
I have a hex bar that I purchased from a guy who told me it was 57lbs.
Always wanted to do a 400lb pull years ago, then one day I just did it and did a 403 triple.
A half year later, I was moving the bar and said "man I am week, this just feels heavy". Weighed it - it was 75lbs.
So all the weights I thought I was training were actually 18lbs more. So my 403 retro'd to 421.
Switched to straight bar after and have not returned to the hex.
