This skill helps calculate the plates needed to achieve a given weight on the barbell.
The supported weights are: 45lbs, 25lbs, 10lbs, 5lbs, and 2.5lbs. The barbell is assumed to weight 45 lbs.
For example: 135 lbs = 45 lbs bar, 45 lbs plate on each side (45+45+45). Barbell will say you need a 45lbs plate on each side for the barbell. 140 lbs = 45 lbs bar, 45 lbs plate and a 2.5 lbs plate on each side.
