Cedie has been with Cathe the Longest. I have the Step N Motion 2 and Cedie is in it. The only times she has not been in a series is in 1999 when CTX, Circuit Max and Cardio Kicks were filmed. She was pregnant at that time and during the Low Impact Series she had scheduling conflicts. Other than that and some of the STS workouts, Cedie has been there.
Jai brought Lorraine to Cathe's workouts. I don't know how Jai got involved but it was around 2003 or so that she began as a cast member.
Brenda joined Cathe's Cast during Cross Train Express in 1999. She was a Firm user and had no idea that Cathe lived in Glassboro NJ just like her. She ended up working out with Cathe and became a permanent cast member. Of all the cast members, Brenda represents the "real" life exerciser.
