Morgan, one idea about cardio is this. You could possibly have them stand at the end of the class and repeat some of the ballet work at a quicker pace standing. However, they might need something to hold on to. Also in a traditional ballet class, you have jumping, but the concern there for some people would be that jumping just on a floor with no shoes is kind of high impact. I will definitely think about it!
Thanks again you southern diva for a wonderful class. So much fun but lots of great work! As someone stated earlier, great addition to barre classes....reminds me of floor barre seen in the past! Thank you for sharing!!
