Load on each side (45 lb bar)
225 lb is the classic two-plate setup. It uses four total 45 lb plates plus the standard 45 lb bar.
Lifters usually talk about plates per side because a normal barbell is loaded symmetrically. When someone says “three plates,” they normally mean three large plates on the left sleeve and three matching plates on the right sleeve.
The total changes if the bar is not 45 lb, if you are using kg plates, if collars are counted, or if the gym uses specialty bars such as trap bars, safety squat bars, or short technique bars.
Yes. Barbell totals include the bar. If you ignore the bar, every plate calculation will be off by 45 lb, 20 kg, or whatever your actual bar weighs.
If you mean one 45 lb plate on each side, the total is 135 lb on a standard 45 lb bar.
These answers use the normal gym convention: plates per side. Two plates means two plates on each sleeve, not two plates total.
