The disks are metallic without rubber coating and the paint layer started to come off in small pieces early on whenever they came into contact with any hard surface.

Essential for small increments that allow continuous and predictable progression. I consider that the 250g. are a manageable increase in load for unilateral exercises for biceps, triceps, and shoulders, the 500g. for unilateral exercises for chest and back, and the 1000g. for unilateral lower body exercises.

The three pairs of disks above, combined with the smaller disks that most gyms have (1.25 and 2.5kg), will allow every trainee to increase the loads as smoothly as possible.
