A quick thought on ages for Jam....
We have only 4 instructors for 2 clubs, 10 classes each week. 2 of our instructors are over 50, 1 over 30, and 1, myself, just under 30. In my opinion, although I've never done a survey, the average age of our particpant is 30-35. Which, I think is wonderful! They LOVE it, and every time them come, they shake it a little bit more!
We have 4 mother/daughter duos, 2 husband/wife duos, and a multitude of 40-somethings that come together after work. I love it! They never judge each other, anyone else, or me....
IMO, the people who most appreciate the "free-ness" of the program are those who are over 20! A wonderful quirk of the Body Jam program!
