Hi Fitnessfanatic! We have quite a bit if rehearsals before we actually film so that the routine flows well and we all know it like the back of our hand. That makes it so that things go more smoothly on film day. It seems we will always have to cut somewhere for one reason or another (ie: technical difficulties, bathroom break, etc.) but we really try to go all the way through if possible. It makes the edit much easier and the overall flow of the workout more natural and true to the moment. To keep us from "cutting" we will have a few camera angles going at the same time. That way, if one of us on the set makes a mistake, we have the possibility of another camera catching the shot from an angle that does not show the mistake so that we don't have to stop. Sometimes we are not able to perfectly fix a mistake but we try the best we can to make that happen.
Oh and yes, there are bloopers but we edit them out or reshoot the footage (ie: the fly that would not leave the set, the tongue tied moments of explaining an exercise, the hair that would not stay out of the eyes, lipstick on the teeth, an outfit that just didn't cut it, a coughing attack that needed water immediately, the photographer who tripped on one of the camera chords and shut down production, etc) :7
