Hospital gowns are sexy.
My wife is having knee surgery today. She's somewhat freaking out since this is her 20+ time but it's been thirty years since the last.
@dmoonfire walking is not as much exercise, but there are some games that you can play to make fun. Steve and Laura are playing Ingress and Pokemon, so they get a few hours walking each day while they play and have lost about 30 LBS each over the last 2 years.
