Morphology
The meaning 'to make one's body more relaxed or limber' is directly derivable from combining 'loosen' (make less tight) with the particle 'up', which here conveys a completive/intensifying result. This verb+particle pattern is common and compositional in English, so a B1 learner who knows the constituents would readily infer the MWE's meaning.
Etymology
Loosen up comes from actually making tight muscles loose by stretching or moving them until they feel softer and can move more easily. That's why loosen up means 'to make your body more relaxed or limber before exercise'.
