First, the conclusion that installing new features at fitness centers will not increase member usage is based on too small a sample to be reliable. The only evidence offered in support of this conclusion is the fact that Healthy Heart fitness center did not experience an increase. Unless it can be shown that Healthy Heart is typical of all fitness centers, the fact that it experienced no increase in member usage is not grounds for concluding that all fitness centers will experience similar results.

Second, the author fails to consider other possible reasons why building an indoor pool failed to increase Healthy Heart�s member usage. Perhaps Healthy Heart�s members are primarily interested in body-building rather than cardiovascular exercise, or perhaps they prefer racquetball; or perhaps they just don�t like swimming. Reasons such as these would help to explain why the addition of a new indoor pool failed to increase member usage. The author�s failure to investigate or even consider other possible explanations for Healthy Heart�s poor results renders the conclusion based upon them highly suspect.

In conclusion, the author�s argument is not convincing. To strengthen the argument it would be necessary to show that Healthy Heart Argument Page numbers fitness center is typical of all fitness centers. Additionally, the author would have to show that other possible reasons for the lack of increase in member usage could be eliminated.
