A weightlifter holding an Olympic barbell loaded with plates ranging from 5 to 25 kilograms A pair of adjustable dumbbells with "standard" plates Grip plates arranged on a plate holder (or "plate tree") A weight plate is a flat, heavy object, usually made of cast iron, [1] that is used in combination with barbells or dumbbells to produce a bar ...
Stating that bar should weigh 25 kg (55 lb) with collars on, effectively permits use of 20 kg (44 lb) bars only, because same as IWF, [3] IPF requires collars to weigh 2.5 kg (5.5 lb) each. [6] The total weight of the barbell varies based on the type and number of plates loaded onto the ends of the bar and the lift being performed, and easily ...
The color designations for these iron plates are as follows: 1 kg is green, 1.5 kg is yellow, 2 kg is blue, 2.5 kg is red, 5 kg and 0.5 kg are white. It is useful to note the color assignment of these iron plates is consistent with the heavier bumper plates (i.e. 1 kg and 10 kg are green, 1.5 kg and 15 kg are yellow, etc.). [19]

The lever will provide a leverage advantage of 2:1, and the incline will have an advantage of 1:√2/2, for a net mechanical advantage of (4/√2):1 ≈ 2.8:1. Thus 50 kg (~491 N) of plates will apply to the user only an equaling weight of 18 kg or a force of ~174 N at the beginning of the motion.
