Define a new set of ability score maximums which represents the highest the score can reach via exercise. These caps are always equal to or higher than the existing maximums, which represent the highest a stat can be increased to through potions of gain ability or other stat-boosting effects. In some cases, the exercise maximum should stay the same and the non-exercise maximum may need to be decreased.

It’s an open question on whether restore ability should be able to restore points to their exercise-only maximums, or just up to the gain-ability maximums.
