The training apparatus is used for the planned strengthening of individual muscle groups. It preferably has two spring bodies, each having a terminal gripping element. The gripping elements of one spring body are terminally arranged on one bar-like spring element and the terminal gripping element of a second spring body on a bar-like spring element can be inserted in the gripping element of the first spring body. Thus, the apparatus can either be tensile stressed and/or compression stressed.
