thanks bro
Its because the plates at my gym are in kilograms, instead of pounds, so when I convert say 15 kilograms to pounds the number isnt very often a round number, like 15 kilograms is 33 pounds.
If its military you could buy a pair of 2.5lb ankle weights and put one on the middle of the bar, they will also help when you do dumbell work because you can put them on your wrists and they will allow you to make small jumps instead of having to make the big 5lb jumps in dumbel weight that most people do.
