Attending your weekly class will give you a sense of community. Each and every member is there for the same reason, to lose weight. So there is a support network ready and waiting to offer their experiences and share their tips with you. The social aspect of attending class is vital to some members also. Members such as retired people and new mums find the class can give their week a little structure if things are quiet for them socially. You also get to build up a relationship with your leader and identify as part of a group.
