Love the combination of interval training on treadmill with weight training/rowing.
Coaches at Naperville are great. They take the time to learn members' name and push members to have good form as well as put forth best effort.
Best training I have done for total body cardio and toning.
There is variety and no workout is the same. The instructors are dedicated, concerned and you can tell they love what they do. They also make sure that you are doing everything with proper form. Nothing is worse then going to a workout/fitness center and have an instructor that is only there for themselves. I also like the fact that no one is pushing personal training for an extra fee. It is like being a part of a family, they all know your name when you walk in.
