Abstract: The present invention relates to an exercise apparatus comprising a weight stack for opposing a given exercise motion through a cable and pulley system. The weight stack comprises a set of weights vertically stacked on each other. The weights have a central aperture formed therein through which a lifting stem is downwardly insertable. Each weight is provided with weight selector means, which are pivotally engagable with said lifting stem for connecting and locking a selectable number of weights to the central lifting stem.

Abstract: The present invention relates to an adjustment device (2) for a training machine (1), especially a triceps extension or a biceps curl, for strengthen training and rehabilitation, having an arm or elbow rest member (50, 51) and pivotably connected handles (23, 24) are provided on each side of a seat (17). Furthermore, the arm or elbow rest members (50, 51) as well as the handles (23, 24) are provided at the lower ends of at both sides of the seat arranged arms (18, 19) pivotably suspended at a position at the top of the training machine (1). Moreover, the adjustment device (2) includes control element (41, 42, 48, 49) for laterally adjusting the positions of the arms and in turn also the arm or elbow rest members (18, 19) as well as the handles (23, 24).
