diastasis recti is mainly a cosmetic thing: it looks funny, but it is not dangerous. There's really no reason to have it surgically repaired other than to improve the appearance; and operations have a fairly high failure rate over time, because the area being stictched is thin. You won't pop open. You can do whatever activity you feel like doing. You could consider an abdominal binder when doing especially strenuous things.
Surgeon has kindly addressed your questions in his comments below and I agree with his assessment.

[A method of surgical treatment of diastasis recti abdominis]
[Article in Russian]
Deriugina MS.
The author describes her original method of operative treatment of patients with diastasis of the rectal muscles of the abdomen intended for liquidation of divarication of recti, formation of the new white line and strengthening of incompetent aponeurotic formations of the abdominal wall with the help of lavsan explants. The method was successfully used in 73 patients with long-standing complex diastasis of the rectal muscles of the abdomen. The average age of the patients was 45.9 years. The long-term results were followed up during the period from 1 to 11 years. No recurrences were noted. Three patients had mild relaxation of the lateral muscles of the abdomen, so they have to use elastic bandages and to fulfill feasible work.
