ABSTRACT:
A technique plate in accordance with the present invention has a dimension ring, two clamping disks and a sleeve. The dimension ring has an internal edge, two side surfaces and a clamping protrusion. The clamping protrusion is formed on and protrudes from the internal surface. The clamping disks are mounted on and clamp the clamping protrusion of the dimension ring. Therefore, compared to a conventional technique plate of the same diameter, the technique plate of the present invention is lighter, so the distance between a bar of a barbell and the ground is higher to prevent beginner's injury.
