A training device for ball games having a first ring member arranged in a first plane and a second ring member arranged in a second plane substantially parallel to the first plane. A plurality of bars connect the first and second ring members to each other, so that a plurality of openings are defined between the ring members and the bars. The device provides openings defined by the ring members and the bars in all directions when the device is placed with one of the ring members resting on the ground. Thus it is possible for several persons to train at the same time since each person is allowed to use a respective one of the openings. At least one net is suspended across the inner space to catch the ball.
