A training device having a concave ramp surface with a lower edge and an upper edge. The concave ramp surface has an angle of curvature greater than 90 degrees from the lower edge to the upper edge such that the ball traveling along the concave ramp surface from the lower edge to the upper edge is directed back over the lower edge. The angle of curvature of the concave ramp surface between the lower edge and the upper edge is variable between the first side and the second side of the body member.
