keeping your back flat on the floor is so you can stabilize your back while you do a specific exercise, hopefully which will loosen or stengthen specific muscles.. But when you are playing or doing normal activities, Yes your back is then rounded
many times but sometimes certain activities (especially tennis or other sports ) will compromise your back in an unsupported position which you don't always feel at the moment but slight injuries are building up thus causing more pain later or the next day..In my case kick serves and running wide for a forehand injure me more than shots on the backhand side where i'm stabilized better
