I've been a Body Pump instructor for 5 years and although the Body Pump workouts follow the same format, the choreography, repetitions and tempo changes for each track vary with each new release. On another note, as a group exercise director with over 15 Body Pump instructors on my staff, each certified Body Pump instructor must purchase their own music, CD and DVD each quarter. It is illegal to burn CDs and your instructor friend could get in serious trouble for doing this.
