Morphology
The parts 'muscle' (strength/physical effort) and 'up' (movement to a higher position) give a B1 learner a clear hint that the expression involves using strength to move upward, so a general sense (pulling oneself upward) is inferable. However, the specific gymnastic meaning—a pull-up immediately followed by a dip in one continuous movement—is a technical, specialized sense that is not fully predictable from the constituents, making the expression only partially transparent.
Etymology
Muscle up is the name of a gym move where you use your muscle to pull yourself up and then push your body over a bar or rings. So it literally means 'to pull yourself up and push over' in fitness.
