Morphology
The combination of 'shape' (condition, fitness) and 'up' (indicating increase or improvement) gives a fairly clear sense of improving physical condition, so a B1 learner who knows the parts could infer the physical meaning. However, the extension to improving behavior or performance is more metaphorical and the particle 'up' in phrasal verbs can signal various nuances, so the exact range of meanings is not fully predictable without exposure.
Etymology
Shape up may come from the picture of a coach helping someone get into better shape and lifting them up in skill or fitness. That's why when someone is told to shape up, it means 'to improve one's behavior, performance, or fitness'.
