I, like you, have just acquired Fluidity and am really loving barre workouts. I have several barre w/o and have never gotten into them before because using back of chair for support simply isn't the same. I'm really surprised by how much I enjoy them and how great I feel afterwards.
After just 3 workouts, I can honestly feel the difference in my body. I feel more supple, leaner and stronger, something I could never tell after doing just cardio, weights or combination of both.
I have been adding about 30 min of cardio before I do Fluidity and feel that it's really working for me. I am also adding 2 strength training sessions (30min) on the other 2 days. I have to say that Fluidity barre has been my best fitness purchase to date.
