They remind me of the original Jane Fonda style workouts!
The trainers do not need a accredited certification to be able to teach these classes.
I’m sure there are some very good instructors and classes but like everything else, do your homework!
In my opinion, there is not just ONE method that does it all, I believe in cross training and always mixing it up!
I have not taken a Barre Class that includes Cardiovascular work.
