By Mike Rosenbaum, About.com Guide

Put your non-throwing hand beneath the discus for support. Your throwing hand (including the thumb) is on top of the discus with your fingers evenly spread. The top knuckle of your four fingers (not the thumb) should touch the rim, with your fingertips over the sides. An alternative grip is to place the index and middle fingers together while evenly spacing the remaining fingers.
