Yep, not only that she wants to avoid hypocrisy  If I’m being totally honest, I don’t think my husband would love me the same if I gained a significant amount of weight. And if the tables were turned, I wouldn’t love him the same, either. I would still love him, yes, but it would be a significant indicator that something was seriously wrong in our relationship if either of us stopped making the effort to stay fit.  She's holding herself to the same standards she holds her husband, which is a sign of a healthy relationship.
