Why is my Dr Telling Me to Wait 12 Weeks Post Op to Return to Crossfit when Everything I Find Online Says 4-6 Weeks?

It’s important to understand that no two patients are ever
exactly alike.Each patient’s starting
point, surgical procedure and post-operative situations are different.For this reason, post-operative care is
individualized following Mommy Makeover surgery.In
general terms, patients can anticipate limited physical activity for two weeks
following surgery.At two weeks, they
are allowed to gradually resume normal activities with the exception of
strenuous activities.Patients can
usually return to work in two weeks if no strenuous activity is involved.After six to eight weeks, they can resume all
their normal activities including heavy lifting, cross fitness and strenuous
activity. It’s
important to listen to your surgeon’s recommendations because he has
information about your procedure that no one else has.It’s also important to go slow at first and
gradually return to your cross fitness routine.This process may take an additional two to three weeks.Make sure you listen to your body.If you’re not ready for a specific activity,
your body will let you know.

Your surgeon knows more about the specifics of your procedure than anyone online, so it's better to listen to them. Your surgeon has taken into account your surgery and condition. Crossfit is a rather intense workout so I suggest you wait as your surgeon recommended.
