i like the fact that they vary daily, there is good variety. Trainers are good generally. I really like Christian at the Roselle-Bloomingdale club. I love that the heart rate is displayed as a metric so you know how hard you are working and if in orange/red you know you are giving it your all. It is difficult to gauge that generally when working out outside the studio. I like the music, i like that there are no phones allowed, its like my one escape from my cell phone.
Improvements could be more variety of class times. Especially on weekends having classes more into the afternoon early evening.
Trainers/Owners are friendly, some of the front desk attendants are not all that impressive in terms of friendliness or knowledge of the product/technology. No one is rude by any means, but many times I find they do not greet me. I personally don't care, but i can see some people finding them to be icy.
