Morphology
The phrase is directly compositional: 'rock' + 'hard' combines into the common intensifier 'rock-hard' meaning extremely firm, applied to 'abs' (abdominal muscles). This metaphorical simile is productive and predictable in English, so a B1 learner who knows the constituent words can infer the meaning.
Etymology
Rock hard abs comes from the image of belly muscles feeling as hard as a rock. The words hard and abs show this idea, so saying rock hard abs means the stomach muscles are 'very firm' and 'well-defined'.
