1. An exoskeleton for supporting an arm of a user, comprising:
a torso attachment device releasably connecting the exoskeleton to a torso of the user;
a bracket connected to the torso attachment device;
a lifting rod connected to the torso attachment device via the bracket and which is reversibly movable in a first direction and a second direction relative to the bracket;
a cantilever configured to support an upper arm of the user, wherein the cantilever is releasably connectable to the upper arm of the user; and
a spring element configured to exert a force on the cantilever and the lifting rod so as to assist in supporting a load lifted overhead by the user while the upper arm of the user is supported by the cantilever which simultaneously moves the lifting rod in the first direction.
