What happens if I unpair a superset?

The two exercises go back to being separate exercises. You work through one and then the other, instead of moving between them.

Nothing you logged is lost. Every set you already finished stays exactly as it is, with the same weight and the same reps. This is different from replacing an exercise, where the sets go with it.

You can pair them again afterwards if you change your mind.
