Wisconsin Athletic Club's Greenfield location is large, well lit and very clean. The staff is friendly and quite knowledgable. For the best personal training my money can buy, ask for Coreen - the wonder woman of triathalons will kick your butt without being intimidating.
The daycare here is wonderfully staffed with lots of toys, sunlight and treats for the kids. Sign in and out is required. There are family activities planned quite often. Sometimes you can drop your kids off at for a nighttime activity and leave for a date night! There are two large pools - both indoor and outdoor, whirpool, sauna and steam room. The locker rooms are always spotless and there is plenty of room to roam. Machines are in great condition and if you are able to go between 9am and about 3pm you will be able to get on any machine you like.
Group excercise classes are available, including the all-popular spin class. There is an outdoor running track for those that hate the treadmill and plenty of ideas for a work-out program for the beginner to the advanced.
