2、 The circulation is just one of the indicators of the popularity of the magazine. What is more， I can find no direct relationship between the popularity of the magazine and the author’s suggestion that we should equip the community with the state-of-the-art excercise machine.

3、 The machines for body building will not necessarily have the same effect on fitness.

In this argument the author concludes that the new community fitness center should be equipped with the state-of-the-art exercise machines featured in Powerflex magazine. In support of this recommendation two reasons are offered： （1） Powerflex contains pictures of bodybuilders using such machines， and （2） Powerflex is a popular magazine， as evidenced by the fact that it frequently sells out at the local newsstand.

This argument is questionable on two counts.

First， a major implication of the argument is that the bodybuilders pictured using the machines in Powerflex magazine reached their state of fitness as a result of using these machines. The only evidence offered to support this contention， however， is the pictures in the magazine. It is possible that the bodybuilders pictured use different equipment for their workouts and are merely posing with the machines for advertising purposes.

Second， the author assumes that machines that are suitable for bodybuilding will also be suitable to help maximize the fitness levels of the town’s residents. This assumption is highly questionable. Machines designed to increase muscle development are significantly different from those designed to increase cardiovascular fitness. Consequently， it is unlikely that the machines pictured in the magazine will be of much use to help maximize the fitness levels of the town’s residents.

In conclusion， this argument is unconvincing. To strengthen the argument the author would have to show that the bodybuilders pictured using the exercise machines actually used the machines to reach their level of muscle development. Additionally， the author would have to show that the machines were suitable for increasing the fitness levels of the persons using them.
