Nope: I don't even like having my picture taken.
Though it might be fun to do a 'mini-workout' that was filmed just for my own purposes (I have a DVD starring me, from a French movie theater--the largest in Europe--that splices images of the tour participants into various movie scenes.)
If Cathe did make me a backgrounder, I'd probably be fired after the first few run-throughs for any of the following reasons :
1) I'd be taking longer breaks when I felt like it: Cathe and the others would be on rep 3 of a set when I finally would join them (and anyone watching the video would be sure to be annoyed by that)
2) I wouldn't follow directions if I didn't like a move, and I'd be modifying moves I found torquey (so again, the home exerciser watching the video would be annoyed by my modifications---though those wishing Cathe would show modifications in her cardio workouts might appreciate it!
)
3) If any cardio or rythmic moves were off the beat of the music (which is rare for Cathe other than STS warm-ups, but I've seen it a couple of times here and there for short periods), I would follow the music and not Cathe
4) If if were a workout like PLB, the rest of the crew would be already on rep 2 by the time I got my barbell weights changed
5) If Cathe called "divebombers" "bombdivers" or said "sets" instead of "reps," I might either roll my eyes or mumble a 'correction'
Nope, I guess video stardom is not for me, LOL!
