I exercised right up to two days before the operation. I swam every day. No reason that they should say no
I was in the gym until the day before surgery. My surgery was on Tuesday, I didn't work out Monday because I was at the office and had stuff I needed to deal with at home Monday evening, so I didn't have time. I was back in the gym doing cardio on a recumbent bike on Saturday.
Best of luck.
Keep on losing!
