I'm not saying people after liberation should go out and bench press 300 lbs, or run an ultra-marathon.
I'm only reporting what the doctor said ... after 48 hours, you can go back to your "normal" routine. (he did also say, watch yourself so you don't bleed because of the blood thinners).
In my wife's case, that's running about 5 miles a day, swimming some days, weight lifting some days. The doctor knew that and he was fine with it ...
She waited 96 hours "just to be safe", and that was her prerogative. But, I'm just reporting what the doctor said.
I don't think he meant, go out and do a routine you didn't do yesterday 48 hours from now. That's just silly.
