Sorry it took me so long, I've been doing all Country Heat lately. But this morning I had so much energy I did Country Heat, Zumba, and decided to finally try some of this as a cool down.
I didn't do all of it, but what I did I loved!
I did the warm up and first number, then did #6 U R the Answer and the cool down. I liked the music, loved that it has a music only/louder option though since it was my first time I played it with instruction, and it was a good balance of movements to follow and freeform. The instructor was fine - she didn't do or say anything annoying.
My only other experience with NIA was Unplugged, which I liked but didn't love. I am a fan of freeform dance - Yoga Trance Dance, The Wave, Delicious Dance. I did purchase the remaining NIA DVDs along with this, but have yet to try them.
