Tracy Anderson Method

Hi everyone! I have a new client that’s obsessed with the Tracy Anderson Method. I’ve never heard of her or workouts but it looks like barre mixed with dance. Anyone ever do her workouts or have an opinion on her method? I’m not going to tell my client to stop doing these classes because she loves them so much but I’m slightly concerned with overtraining and want to make sure I give her a program that won’t have her over-doing it!
