I have done callanetics before and do have it on video.
I love doing the video because of the stretching. She has a very calming voice. I practice it like I would if I did yoga. Yoga is not my thing but callanetics gets me to relax and stretch my muscles.
When I started, I lost some weight but I was running as well. I can't honestly say it was callanetics.
But I love Callan Pickney. She has a beautiful dancers physique that I covet when I do the vids!
