1. A strength training apparatus (10) having a manually operable operating element (30) coupled via a lever mechanism (20) to at least one unit (39, 41, 42) generating a resistance,
the lever mechanism (20) having, at a distance from a handle element (32) of the operating element (30), at least one first joint (26) mounted in a first axis (21) via at least one first joint lever (25), and the lever mechanism (20) having at least one second joint (35) disposed between the at least one first joint (26) and the handle element (32),
the at least one second joint (35) being mounted at least indirectly in a second axis (22) via at least one second joint lever (36), one of the first and second axes (21, 22) being disposed in operative connection with the at least one unit (39, 41, 42), the other of the first and second axes (21, 22) being locked or being pivotable about a small angle,
wherein the at least one second joint lever (36) being connected to the second axis (22) via a coupling link (38),
wherein the first and second axes (21, 22) each being lockable or pivotable about the small angle individually and being operatively connectable to the at least one unit (39, 41, 42) individually,
wherein the at least one first joint lever (25) and the at least one second joint lever (36) being disposed on a same side of a corresponding one of at least one rods (28) of the operating element (30),
wherein the at least one second joint (35) being coupled to the corresponding one of the at least one rods (28) at a location between the at least one first joint (26) and the handle element (32), the at least one second joint lever (36) being fixed at a first end thereof via the at least one second joint (35) so as to be pivotable at the at least one second joint (35),
and wherein, at an opposite second end of the at least one second joint lever (36) facing away from the at least one second joint (35), the coupling link (38) being connected to the at least one second joint lever (36) via a third joint (37) so as to be pivotable on a first end of the coupling link (38) and non-rotatably coupled to the second axis (22) on an opposite second end of the coupling link (38).
