What does Personalize do?

It fills in the weights on a routine from your own history. A routine somebody shared with you then shows your numbers instead of theirs.

Routines arrive with no weights on them on purpose. What is heavy for the person who built the routine may be nothing like what is heavy for you.

Personalize touches the weights only. The exercises, the order and the number of sets stay exactly as the routine has them.
