Both a weight-loss center and a health club would be pleased to learn that health and fitness, along with individualism, mastery and control, and self-improvement are core values common in the _____ of the u.s.
I think the best answer would be culture. This is because all these aspects would motivate people going to the weight loss canter as well as health club in an attempt to live responsibly and healthy. In turn this would promote the business of those who own the centers as many individuals have adopted those aspects.
